A quiet valley beyond Gstaad
Most visitors who make it as far as the upper Simmental are heading for Gstaad, and Lenk im Simmental gets treated as an afterthought a few kilometres further up the valley. That is a mistake if what you actually want is waterfalls, marmots and farmhouses rather than boutiques. Lenk sits at around 1,068 metres, at the point where the Simmental narrows and the road starts to climb toward the Wildstrubel massif, and it functions as a proper working village with a thermal bath, a handful of hotels and none of the price tags you find in Gstaad fifteen minutes down the valley.
The wider region, sometimes marketed together as Adelboden-Lenk, sits west of the Kander valley and is usually reached from Interlaken via Spiez rather than through Grindelwald or Lauterbrunnen. If your itinerary already covers Adelboden, Lenk is an easy add-on: the two are connected by postbus and by a summer hiking link over the Hahnenmoos pass. If you are coming from Interlaken itself, treat this as a full day rather than a quick add-on to something else, because the travel time works against combining it with a second major excursion on the same day.
What draws people here, and what this guide covers, is three things: a genuinely good waterfall walk above Iffigenalp, a marmot trail reached by gondola from Betelberg, and the Diemtigtal side valley, which has been recognised for keeping its historic farm architecture intact rather than converting it into ski chalets.
Getting to Lenk from Interlaken
There is no direct train. From Interlaken Ost or Interlaken West you go to Spiez, change onto the line toward Zweisimmen, then change again for the short final stretch to Lenk. Budget around 1h30 door to door, with the two changes being the main variable — connections are usually tight but reliable in typical Swiss-rail fashion.
| From | Change at | Approx. journey time |
|---|---|---|
| Interlaken Ost / West | Spiez, then Zweisimmen | About 1h30 |
| Spiez | Zweisimmen | About 1h05 |
| Zweisimmen | — (direct) | About 20 min |
A regular point-to-point ticket works, but if you already hold a Swiss Travel Pass for the wider trip, this route is fully covered and worth building into a day trip from Interlaken rather than paying twice. There is no need to book seats; regional trains here run frequently enough that a missed connection just means a 30 to 60 minute wait rather than a lost day.
If you are driving, the valley road up from Spiez via Erlenbach and Zweisimmen is straightforward, and parking in Lenk itself is metered but not scarce outside peak ski weekends.
The Iffigfall and Simmenfälle: a trail with seven waterfalls
This is the reason most hikers detour to Lenk. From the village, a postbus (or toll road for drivers) climbs to Iffigenalp, an alpine meadow at around 1,584 metres that serves as the trailhead. Lenk’s own tourist board markets the onward route as a “seven waterfalls” walk, and while the exact count depends on how you split cascades that merge and separate, the sense of the marketing is accurate: this is an unusually waterfall-dense short hike for the region.
The main target is the Iffigfall itself, a broad fall dropping roughly 100 metres down a rock face at the head of the meadow, reached by an easy, largely flat path from the Iffigenalp car park in about 30 to 40 minutes each way. Families with young children manage this leg without difficulty; pushchairs will struggle on the final stony stretch.
Continue past the Iffigfall and the path steepens toward the Iffigsee, a small alpine lake, and the Simmenfälle, the falls close to where the Simme river itself rises. This section adds genuine ascent and turns the outing into a half-day hike of 3 to 4 hours return, with sturdy footwear required rather than optional. The reward is a string of smaller cascades feeding into the main falls, plus views back down the Simmental that most day-trippers to Gstaad never see.
| Section | Distance (one way) | Time (one way) | Terrain |
|---|---|---|---|
| Iffigenalp to Iffigfall | About 2 km | 30–40 min | Flat, easy path |
| Iffigfall to Iffigsee / Simmenfälle | About 2.5 km | 1–1.5 hr | Steeper, rockier |
For a broader comparison of what counts as a good half-day walk in this part of Switzerland, our round-up of the best day hikes from Interlaken and the dedicated Oeschinensee hiking guide cover the more famous alternatives over in the Kander valley, useful if you are trying to decide which valley deserves your one free hiking day.
Betelberg and its marmot trail
Above Lenk on the opposite side of the valley, the Betelberg gondola climbs to just over 2,000 metres in around 20 minutes, saving a genuinely large amount of ascent. At the top, a marked marmot trail — the Murmeltierweg — loops through the kind of rocky, grassy terrain marmots actually favour, with information panels on the animals along the way.
Sightings are not guaranteed and depend heavily on time of day: early morning and late afternoon in summer are better than the middle of a hot day, when marmots retreat underground. The trail itself is gentle and largely flat once you are off the gondola, which is what makes it a reliable choice for families who want mountain views without a demanding walk. Our general wildlife and marmots guide covers where else in the region to try if Betelberg does not deliver.
In winter, the same lift infrastructure switches over to serve the Adelboden-Lenk ski area, one of the larger connected ski regions in the Bernese Oberland outside the Jungfrau ski lifts themselves. If skiing is part of your trip rather than summer hiking, our Adelboden-Lenk ski guide has piste details and lift pass pricing.
The Diemtigtal: a valley protected as a landscape
A short drive or postbus ride from Lenk, back down the Simmental and up a side valley near Erlenbach, sits the Diemtigtal. In 2013 the conservation organisation Pro Natura named it Landscape of the Year, largely on the strength of how much traditional farm architecture the valley has kept in working agricultural use, rather than sold off and converted into second homes.
What you actually see on a visit are wooden farmhouses dating from the 18th and 19th centuries, low-roofed and long, with carved balconies that are still lived in and farmed rather than preserved behind glass. Springenboden, reached by a short cable car from the valley floor, is the usual base for exploring further, with hiking trails fanning out toward the Wildstrubel side of the range. This is not a place with a single headline sight; it rewards a slower half-day of walking between hamlets rather than a checklist visit.
Combined with Lenk, the Diemtigtal turns a single-focus day into a genuine two-day trip, and it pairs naturally with a stop at Kandersteg and the Oeschinensee or a night based in Frutigen if you are working your way along the wider Kandertal-Simmental region rather than doing a there-and-back from Interlaken.
Costs, timing and where to base yourself
None of this is expensive by Bernese Oberland standards, but it is not free either. Expect the following as a rough guide for one adult on a day trip from Interlaken:
| Item | Approx. cost (CHF) |
|---|---|
| Return train, Interlaken–Lenk | 45–60 (less with Swiss Travel Pass or Half Fare Card) |
| Postbus, Lenk–Iffigenalp (return) | 15–20 |
| Betelberg gondola (return) | 30–38 |
| Lunch at a mountain restaurant | 20–35 |
| Total, one activity plus lunch | 110–150 |
Doing both the waterfall trail and Betelberg in one day is physically possible but tight, and it pushes the daily spend toward CHF 180–200 once you add both lift tickets. Most visitors are better served picking one and saving the other, or spreading the two over an overnight stay. For a wider sense of how this compares across the region, see our Interlaken travel costs guide; Lenk runs noticeably cheaper than anything based directly in the Jungfrau lift network.
If you are building a longer stay around hiking rather than a single day trip, our six-day hiking itinerary shows where a Lenk detour fits against the more heavily promoted routes near Grindelwald and Mürren, and Spiez makes a sensible overnight base roughly midway between Interlaken and the Simmental if you want to shorten the daily commute on a multi-day trip.
Tours worth booking ahead in the wider Simmental
Lenk itself has no fixed-departure tours, but several bookable experiences in the surrounding Adelboden-Lenk and Kandertal area are worth reserving before you arrive, since summer weekends fill the smaller lifts and guided slots. For a look at the neighbouring Engstligenalp plateau, the Engstligenalp aerial tramway ticket from Adelboden covers a comparable alpine bowl a short hop from Lenk.
If you want a guided summit hike rather than a solo walk, the guided ascent of the Tschentenalp with a Swiss triathlete is a more structured half-day out of Adelboden. And for an easy, family-friendly outing that pairs well with a shorter Lenk morning, the Blausee lake visit with a Swiss fondue lunch sits just over the hill in the Kander valley.
Lenk and the Simmental: your questions answered
How do I get to Lenk from Interlaken?
Take the train from Interlaken Ost or Interlaken West to Spiez, change for Zweisimmen, then change again for the short final leg to Lenk im Simmental. The whole journey runs about 1h30 and involves two changes, both usually with short, well-signed connections rather than a mad dash across the platform.
How long is the Iffigfall and Simmenfälle waterfall trail?
From the Iffigenalp car park, the walk to the Iffigfall and back takes around 1 to 1.5 hours at an easy pace. Continuing to the Simmenfälle and the Iffigsee area, where several smaller falls join the route, turns it into a half-day outing of 3 to 4 hours.
Is the Betelberg marmot trail suitable for children?
Yes. The Betelberg gondola does the climbing, and the marmot trail (Murmeltierweg) from the top station is a gentle, mostly flat loop with information boards, so it works well for children, provided you accept that marmots are wild animals and sightings are not guaranteed.
What makes the Diemtigtal’s farmhouses special?
The Diemtigtal was named a Landscape of the Year by the conservation group Pro Natura, largely because so many of its wooden farmhouses date from the 18th and 19th centuries and remain in agricultural use rather than converted into holiday chalets. Look out for the carved balconies and long, low roofline typical of Simmental building style.
Can I visit Lenk as a day trip from Interlaken, or should I stay overnight?
A day trip works if you pick one focus, either the waterfall trail or Betelberg, since travel time eats close to 3 hours of the day round trip. Staying one night in Lenk or nearby Adelboden lets you do both plus a stop in the Diemtigtal without rushing.
Is Lenk worth visiting if I’ve already seen Gstaad?
It is a different experience rather than more of the same. Gstaad trades on boutiques and a well-heeled reputation; Lenk is a working alpine village with thermal baths, dairy farming and considerably lower prices for lunch and lift tickets.
When do the Iffigenalp road and Betelberg gondola run?
The postbus and toll road up to Iffigenalp typically operate from around early June to mid-October, snow permitting, and close outside that window. The Betelberg gondola runs a longer season for summer hiking and winter skiing, but both lifts close for scheduled maintenance in spring and autumn, so check current dates before setting off.
