You need at least two full days in Interlaken.

That does not mean spending two days in Interlaken itself. The town works best as a base for the surrounding valleys, mountain villages, lakes and hiking trails.

With two days, I would visit Lauterbrunnen and Mürren on the first day, then hike beneath the Eiger and finish in Grindelwald on the second.

A third day gives you enough time for Oeschinensee near Kandersteg. With four days, you can slow down with a boat journey across Lake Thun and an afternoon in Thun.

My recommended structure is:

• Two days: Lauterbrunnen and Mürren + Eiger Trail and Grindelwald
• Three days: Add Oeschinensee
• Four days: Add a Lake Thun cruise and Thun
• Five days or more: Add weather buffers, alternative hikes or a slower day

This itinerary is designed for summer and early autumn, when the hiking trails are open. Each day includes an active main route and a lighter alternative for travellers who prefer villages, trains and cable cars.

How many days do you need in Interlaken?

Length of stay	What you can experience
1 day	Lauterbrunnen and possibly Mürren
2 days	Lauterbrunnen/Mürren and the Eiger/Grindelwald area
3 days	Add Oeschinensee and Kandersteg
4 days	Add Lake Thun and the town of Thun
5+ days	More hiking, weather flexibility and slower travel

For most first-time visitors, three or four days is ideal.

Two days covers the essential mountain scenery but leaves little flexibility. Three days adds one of the most beautiful alpine lakes in the region. Four days creates a better balance between hiking, mountains, water and towns.

If your arrival and departure days are only partial days, do not count them as full sightseeing days. A “three-day stay” with a late arrival and early departure may give you only one usable day.

Is Interlaken worth using as a base?

Yes.

Interlaken itself is not the most beautiful destination in the region, but its location is extremely practical. From Interlaken Ost, trains branch towards Lauterbrunnen and Grindelwald. From Interlaken West, you can board boats on Lake Thun or travel towards Spiez and Kandersteg.

That makes Interlaken a useful base for:

• Lauterbrunnen
• Mürren and Gimmelwald
• Wengen
• Grindelwald
• The Eiger Trail
• Oeschinensee
• Lake Thun
• Thun

You can return to the same hotel each evening instead of moving your luggage between mountain villages.

My Interlaken travel guide explains the town, transport and surrounding attractions in more detail.

If you are still choosing accommodation, read my comparison of Interlaken, Lauterbrunnen and Grindelwald.

My ideal Interlaken itinerary

I would prioritise five experiences:

1. Lauterbrunnen
2. Mürren and Gimmelwald
3. The Eiger Trail
4. Oeschinensee
5. A Lake Thun cruise and Thun

I would not treat Jungfraujoch or Harder Kulm as mandatory.

Both can be worthwhile, but they are not automatically better than hiking beneath the Eiger, walking through the Lauterbrunnen Valley or seeing Oeschinensee from above. They also add considerable expense.

This itinerary focuses on places where the landscape itself is the experience.

Two days in Interlaken

With two full days, divide your time between the two major valleys.

• Day one: Lauterbrunnen, Mürren and Gimmelwald
• Day two: Eiger Trail and Grindelwald

I would not combine Lauterbrunnen and Grindelwald on the first day simply to fit in more destinations. With only two days, each valley deserves one dedicated day.

Day 1: Lauterbrunnen, Mürren and Gimmelwald

Begin at Interlaken Ost and take the train into the Lauterbrunnen Valley.

The journey takes around 20 minutes. Check that you are sitting in the correct section of the train because services towards Lauterbrunnen and Grindelwald may initially run together before separating at Zweilütschinen.

My Interlaken to Lauterbrunnen train guide explains the connection, tickets and stations.

Morning: travel up to Mürren

From Lauterbrunnen, take the cable car to Grütschalp and continue by mountain train to Mürren.

The final railway journey follows the mountainside above the valley, with views towards the Eiger, Mönch and Jungfrau. It is one of the most scenic short train journeys in the region.

Mürren is car-free and sits approximately 1,650 metres above sea level. Spend some time walking through the village before beginning the descent.

My complete Interlaken to Mürren guide covers both access routes and explains when to travel via Grütschalp or Stechelberg.

Active route: hike via Gimmelwald to Lauterbrunnen

From Mürren, follow the regular hiking route towards Gimmelwald and continue into the Lauterbrunnen Valley.

I completed the walk from Mürren via Gimmelwald to Lauterbrunnen in approximately three hours.

In normal summer conditions, it is technically straightforward:

• Manageable for beginners with reasonable fitness
• Easy for experienced hikers
• Mostly downhill
• Potentially tiring for the knees
• Best with shoes that provide proper grip

Do not confuse the normal hiking path with the Mürren–Gimmelwald via ferrata. The via ferrata is an exposed protected climbing route that requires appropriate equipment and experience.

The hike works especially well as a first day because it reveals the landscape gradually. You begin high above the valley, pass through two car-free mountain villages and finish beneath the waterfalls.

My Mürren to Lauterbrunnen hike guide provides more detail about the route.

Lighter alternative: cable car via Gimmelwald and Stechelberg

If you do not want to hike for three hours:

1. Explore Mürren on foot.
2. Take the cable car towards Gimmelwald.
3. Stop in Gimmelwald if time allows.
4. Continue by cable car to Stechelberg.
5. Take the bus through the valley to Lauterbrunnen.

This gives you much of the same scenery with considerably less walking.

You can stop near Staubbach Falls or walk a short section of the valley before returning to Interlaken.

What not to add

Do not add Wengen, Schilthorn and Trümmelbach Falls simply because they appear nearby on a map.

Each extra attraction adds another transfer, entrance or deadline. The Mürren and Gimmelwald route already creates a complete day.

Day 2: Eiger Trail and Grindelwald

The second day should focus on the Grindelwald side of the region.

Where Lauterbrunnen is picturesque, Grindelwald feels larger and more imposing. The Eiger dominates the valley, and the scale of the mountain becomes clearest when you walk directly beneath its north face.

Morning: travel towards Eigergletscher

Take the train from Interlaken Ost towards Grindelwald and continue to the Eigergletscher area using the appropriate mountain connection.

Depending on your ticket and route, you may travel via Grindelwald Terminal and the Eiger Express or use the mountain railways through the region.

Check the current connection in SBB or the Jungfrau Railways timetable.

My Interlaken to Grindelwald train guide explains the initial journey from Interlaken.

Active route: Eigergletscher to Alpiglen

The classic Eiger Trail begins at Eigergletscher station and descends to Alpiglen.

The official route takes approximately two hours and drops from around 2,348 metres to 1,616 metres. It runs directly beneath the Eiger North Face.

This is one of the best hikes near Interlaken because the scenery feels enormous without requiring a full-day technical mountain route.

Expect:

• Close views of the Eiger
• Rocky mountain terrain
• A sustained descent
• Open views towards Grindelwald
• Changing weather at altitude
• Uneven paths requiring suitable shoes

Although it is primarily downhill, do not assume it is effortless. Descending over rocky terrain can be tiring, particularly for your knees.

At Alpiglen, take the train down towards Grindelwald.

Afternoon in Grindelwald

Spend the remainder of the day in Grindelwald village.

Walk along the main street, browse the shops, have a drink on a terrace and look back towards the mountains you just walked beneath.

Grindelwald is more tourist-oriented than Mürren or Gimmelwald, particularly in the afternoon. Expect busy streets and crowded terraces during summer.

The village itself is not the main reason for dedicating this day to Grindelwald. The Eiger scenery is.

Lighter alternative: Eigergletscher and Grindelwald without the hike

If the Eiger Trail is closed or you prefer less walking:

1. Travel to Eigergletscher.
2. Spend time enjoying the viewpoints.
3. Return towards Grindelwald Terminal.
4. Explore Grindelwald village.
5. Stop for lunch or a drink.
6. Return to Interlaken.

Another option is Grindelwald First, although that creates a different kind of day. First is better for organised attractions, a gondola journey and accessible mountain views.

If you want an easy hike from First, consider Bachalpsee. I would not combine the complete Bachalpsee hike with the Eiger Trail on the same day.

Two-day itinerary summary

Day	Active itinerary	Lighter alternative
1	Mürren–Gimmelwald–Lauterbrunnen hike	Mürren and Gimmelwald using cable cars
2	Eiger Trail from Eigergletscher to Alpiglen	Eigergletscher viewpoint and Grindelwald

Two days is enough for the essential Jungfrau Region experience, but there is no spare day if the weather is poor.

If clouds completely cover the Eiger on day two, consider swapping the days or adjusting the route rather than completing a view-dependent hike in poor visibility.

Three days in Interlaken

With three days, add Oeschinensee.

Your itinerary becomes:

• Day one: Lauterbrunnen, Mürren and Gimmelwald
• Day two: Eiger Trail and Grindelwald
• Day three: Oeschinensee Panorama Trail

This is my preferred three-day itinerary because every day has a different character:

• A waterfall valley and mountain villages
• A major Alpine face and rugged trail
• A blue mountain lake surrounded by cliffs

Day 3: Oeschinensee and Kandersteg

Oeschinensee lies above Kandersteg, outside the immediate Jungfrau Region.

From Interlaken, travel by train via Spiez to Kandersteg. From the station, walk or take the seasonal local bus to the Oeschinensee cable-car valley station.

The train journey to Kandersteg normally takes around 1 hour to 1 hour 15 minutes, depending on the connection.

Read my complete Oeschinensee day trip from Interlaken guide before travelling.

Active route: Oeschinensee Panorama Trail

Take the cable car from Kandersteg and follow the panoramic mountain route above Oeschinensee.

This is the best way to appreciate the lake’s scale. From the shore, Oeschinensee is beautiful. From above, you see the complete blue lake enclosed beneath steep cliffs.

The higher panoramic route is not a casual lakeside walk. It includes substantial elevation, mountain terrain and exposed-looking viewpoints.

Bring:

• Hiking boots
• Water
• Food
• Sun protection
• An extra layer
• A downloaded route
• Enough time before the final cable-car descent

Check the official trail status immediately before hiking. Weather, snow and trail closures can affect access even when the cable car itself is operating.

My Oeschinensee Panorama Trail guide covers the hike and viewpoints in detail.

Lighter alternative: direct walk to the lake

Take the cable car and walk directly from the mountain station to Oeschinensee.

The lake is approximately 20–30 minutes away using the normal accessible path. You can spend time at the shore, eat, take photographs and return without completing the higher trail.

This is the better choice for:

• Families with young children
• Visitors with limited hiking experience
• Poorer mountain conditions
• Anyone wanting a relaxing lake day
• Travellers tired after the first two active days

An electric shuttle may operate during the summer, with priority for visitors with limited mobility, but availability should be checked rather than assumed.

Reservations

For the busiest part of the 2026 summer season, the official Oeschinensee information requires an ascent reservation between June 20 and September 20.

Requirements may change in later seasons. Check the official reservation and operating information when planning your visit.

Even if you have a Swiss Travel Pass or Half Fare Card, the cable car may require a separate discounted ticket and time slot.

Should you combine Oeschinensee with Blausee?

You can, but I would not do so after the Panorama Trail.

The higher trail deserves most of the day. Adding another lake makes the schedule tighter and reduces the time available at Oeschinensee.

Combine the lakes only if you choose the direct, lighter visit and start early.

Three-day itinerary summary

Day	Main experience	Overnight base
1	Lauterbrunnen, Mürren and Gimmelwald	Interlaken
2	Eiger Trail and Grindelwald	Interlaken
3	Oeschinensee Panorama Trail	Interlaken

Three days is the minimum stay I would recommend to most active first-time visitors.

Four days in Interlaken

With four days, add Lake Thun and Thun.

The itinerary becomes:

• Day one: Lauterbrunnen, Mürren and Gimmelwald
• Day two: Eiger Trail and Grindelwald
• Day three: Oeschinensee
• Day four: Boat across Lake Thun and visit Thun

The fourth day intentionally has a slower pace. After three mountain days, sitting on a boat and exploring a town creates a better balance than adding another cable car.

Day 4: Lake Thun boat trip and Thun

Begin at Interlaken West.

The boat landing for Lake Thun is beside the station, which is why this day uses Interlaken West rather than Ost.

My Interlaken West versus Interlaken Ost guide explains which side of town serves each lake and mountain route.

Morning: boat from Interlaken to Thun

Take a scheduled boat across Lake Thun.

The full journey is not merely transport. It is the main experience of the morning, passing lakeside villages, castles and mountain views as you travel towards Thun.

Boat schedules vary considerably by season. Some services do not operate year-round, and the number of departures changes throughout the year. Check the current BLS timetable before building the day around a specific sailing.

Bring an extra layer. Even on a warm day, the open deck can feel cool once the boat begins moving.

Afternoon: explore Thun

Thun is compact enough to explore on foot.

Spend the afternoon:

• Walking through the old town
• Seeing the covered wooden bridges
• Walking beside the River Aare
• Visiting the castle area
• Stopping for lunch or coffee
• Exploring the raised pavements of Obere Hauptgasse

Thun feels more like a complete Swiss town than Interlaken, making it a worthwhile contrast to the mountain villages from the previous days.

You can learn more from my Thun destination guide.

Return to Interlaken by train

Return from Thun to Interlaken by train.

There is no reason to take the boat in both directions unless you specifically want a full day on the water. The train is faster and lets you create a one-way circular excursion.

This route also removes the pressure of catching the final boat back.

Lighter alternative

The boat-and-Thun day is already the lightest itinerary.

If you need an even slower day:

• Take the boat only as far as Spiez
• Explore Spiez and its lakeside castle area
• Return by train
• Spend the evening in Interlaken

Four-day itinerary summary

Day	Active itinerary	Lighter alternative
1	Hike Mürren–Gimmelwald–Lauterbrunnen	Use cable cars and bus
2	Eiger Trail	Eigergletscher viewpoint
3	Oeschinensee Panorama Trail	Direct lakeside visit
4	Boat to Thun and city walk	Shorter boat trip to Spiez

Four days is the best overall length for this itinerary. You experience mountains, valleys, villages, hiking, an alpine lake and a historic town without forcing everything into one exhausting schedule.

What if you only have one day in Interlaken?

Choose Lauterbrunnen.

Travel from Interlaken Ost to Lauterbrunnen, continue to Mürren and return via Gimmelwald and Stechelberg—or complete part of the hike if conditions and time allow.

Lauterbrunnen is more picturesque than Grindelwald, while Mürren adds the mountain-village experience that the valley floor alone cannot provide.

If you are determined to see both valleys, use my itinerary for Lauterbrunnen and Grindelwald in one day.

That combined day is possible, but you must make deliberate choices. I would not recommend trying to include Mürren, Grindelwald First and Bachalpsee together.

What if you have five days?

Use the fifth day as a weather buffer.

Mountain itineraries depend on visibility and trail conditions. Locking each destination to one specific day can leave you hiking beneath clouds while a clearer valley sits nearby.

With five days, you can:

• Move the Eiger Trail to the clearest day
• Postpone Oeschinensee if the higher trail is closed
• Add Wengen
• Visit Grindelwald First and Bachalpsee
• Spend more time around Lake Thun
• Rest after several hiking days
• Add Jungfraujoch if the weather and budget justify it

I would not fill the fifth day before arriving. Keep it flexible.

Where should you stay?

For this itinerary, Interlaken is the most practical base.

Stay near Interlaken Ost if:

• Lauterbrunnen and Grindelwald are your priorities
• You want the shortest morning transfers
• You are completing several mountain day trips
• You prefer easy access to trains

Stay near Interlaken West if:

• Lake Thun is important
• You prefer the western town centre and Unterseen
• You want more restaurants nearby
• You do not mind travelling to Ost for mountain trains

Stay centrally if:

• You want balanced access to both stations
• You enjoy walking through town
• Your itinerary includes both mountains and Lake Thun

For this particular two- or three-day itinerary, I would choose accommodation near Interlaken Ost. For four days, central Interlaken provides a useful compromise.

Do you need a car?

No.

Every day in this itinerary works by train, cable car, bus and boat.

A car does not reach Mürren, cannot take you to Eigergletscher and cannot drive to Oeschinensee. You would still depend on mountain transport while also needing to find parking.

Public transport is not merely the practical alternative here; it is part of the experience.

Which travel pass is best?

The best option depends on:

• Number of travel days
• Your age
• Whether you already have a Swiss Travel Pass
• Which mountain railways you use
• Whether you choose the active or lighter routes
• Your wider Swiss itinerary

Compare:

• Individual tickets
• Swiss Half Fare Card
• Swiss Travel Pass
• Jungfrau Travel Pass
• Regional passes covering the Bernese Oberland

Do not assume one pass covers every cable car. Standard trains may be fully included while mountain transport receives only a discount.

Calculate the exact journeys in your itinerary before buying.

When should you visit?

This itinerary works best from late June to September.

The timing depends on snowmelt and trail openings.

June

Valleys are green and waterfalls can be powerful, but snow may remain on higher routes. The Eiger Trail and Oeschinensee Panorama Trail may not yet be open.

July and August

These months offer the most reliable hiking conditions, but also the largest crowds.

Start early, reserve required cable-car time slots and expect Grindelwald, Lauterbrunnen and Oeschinensee to become busy.

September

September often provides an excellent balance of open trails, cooler temperatures and fewer visitors.

Days become shorter, so check final mountain-transport departures.

October

Lower walks may remain possible, but snow and seasonal closures become increasingly likely. Do not build a trip around the Eiger Trail or Oeschinensee Panorama Trail without confirming their status.

What should you do in bad weather?

Do not follow the itinerary order rigidly.

Before each mountain day:

1. Check the forecast.
2. Check local webcams.
3. Check trail and cable-car status.
4. Move the clearest mountain activity to that day.

The Lake Thun and Thun excursion is the easiest day to use when high mountains are cloudy, although heavy rain can still make the boat and town less enjoyable.

If the Eiger is completely hidden, postpone the Eiger Trail. If the Oeschinensee Panorama Trail is wet, snowy or closed, use the direct lakeside route or move the visit.

Flexibility matters more than following a perfect written schedule.

How active is this itinerary?

The main four-day version includes three walking days:

• Approximately three hours descending from Mürren
• Approximately two hours on the Eiger Trail
• A more demanding panoramic hike above Oeschinensee

That is manageable for active travellers, but the consecutive downhill routes can become tiring.

Use the lighter alternatives if:

• You are new to hiking
• You have knee problems
• You are travelling with young children
• The weather is poor
• You prefer sightseeing to trail time
• You simply need a rest day

You do not need to complete every hike to experience the region.

Common itinerary mistakes

Counting travel days as full days

A late arrival is not day one. Count the number of mornings when you can leave early and use the whole day.

Scheduling every mountain in advance

Weather can make your carefully chosen order irrelevant. Decide the final order after checking local conditions.

Trying to include Jungfraujoch automatically

It is famous and expensive, but it is not compulsory. The Eiger Trail may give active visitors a more direct connection to the mountain.

Combining too many valleys

Lauterbrunnen and Grindelwald are close geographically but lie on separate railway branches. Transfers consume more time than the map suggests.

Treating Interlaken itself as the main attraction

Use Interlaken as a base. The strongest experiences are in the surrounding region.

Underestimating downhill hikes

Both the Mürren route and Eiger Trail involve substantial descent. Downhill walking can be tiring even when your breathing feels comfortable.

Ignoring seasonal trail closures

A cable car operating does not mean every hiking trail is open.

Leaving Oeschinensee reservations too late

High-season ascent slots can fill. Check the current reservation rules before travelling.

How many days in Interlaken: final verdict

Stay for two days if your time is limited and you mainly want to see the Jungfrau Region.

Stay for three days if you also want Oeschinensee and do not mind an active itinerary.

Stay for four days for the best-balanced first visit, adding Lake Thun and Thun after the mountain days.

My ideal first-time itinerary is:

1. Lauterbrunnen, Mürren and Gimmelwald
2. Eiger Trail and Grindelwald
3. Oeschinensee Panorama Trail
4. Lake Thun boat and Thun

It leaves out some famous attractions, but that is intentional.

A good Interlaken itinerary is not about collecting every cable car and viewpoint. It is about choosing a few landscapes and having enough time to experience them properly.
