Blausee And Oeschinensee: Two Alpine Lakes From Lauterbrunnen

Blausee Is Small, Managed And Always Open

Blausee is tiny. About 0.64 hectares of water at 887 m elevation, next to the Kander river in Kandergrund, framed by parkland rather than raw mountain terrain. It has been run privately by Blausee AG since long before, with hospitality on site since 1978, and that shows in the experience.

The paths are built, the trout farm is an attraction in its own right, and the glass-bottom boat drifts over water so clear you watch the fish below. The park opens 365 days a year from 09:00, typically until about 21:00, which makes it the easier target for a late arrival or a winter visit when the high trails are snowed in. Admission is charged, it varies by season and day of week, and the price simply is not published as one stable figure on the operator's own pages.

If you want a short, comfortable, well-kept stop rather than a mountain hike, Blausee delivers exactly that.

Oeschinensee Is Big, Wild And UNESCO Listed

Oeschinensee is a different animal. The lake covers 1.115 km2, holds water up to 56 m deep, and sits at 1,578 m above Kandersteg. Its basin was formed by prehistoric landslides, and the scale of the rock walls around it tells you so at a glance.

Since 2007 it has been part of the Swiss Alps Jungfrau-Aletsch UNESCO World Heritage Site, which puts it in the same protection tier as the Aletsch glacier and the high peaks above our own valley. You reach it on the Kandersteg-Oeschinensee cable car, then walk the last stretch on foot, so the arrival feels earned in a way Blausee's does not. The trade-off is structure: a fixed cable car fare by season, operating windows that close in the shoulder weeks, and an online time-slot reservation required for the ascent through 8 November 2026.

If you want mountain air and open water, this is the one that justifies the extra train change.

Everything starts with the train to Kandersteg. From Lauterbrunnen the journey takes about 1 hour 39 minutes with 2 changes, typically at Interlaken Ost and then Spiez. It is a normal national timetable connection, so you can read the exact departure in the SBB app on the day.

There is no fixed point-to-point fare published for this route, the national distance-based price appears in the SBB app and at the ticket machine. Kandersteg station is the gateway village for both lakes, and from there the two options split. For Blausee, a direct bus runs from the station to the Blausee BE stop in 12 minutes with no change, per Blausee AG's own arrival page.

For Oeschinensee, the cable car valley station is a short walk from the train, and you ride up from there. If you are piecing together the local legs of the journey, our getting around Lauterbrunnen page covers the valley's own transport, and the wider options are on the day trips hub. One warning worth repeating: a cable car time-slot reservation does not guarantee a parking space at Kandersteg, so arriving by train is the calmer choice.

The Lake, The Boat And The Trout Farm

The lake itself sits at 887 m and covers about 0.64 hectares near the Kander river in Kandergrund. That is genuinely small, you can walk its shore in minutes, and the point of the visit is the water rather than the distance covered. The day ticket includes a ride on the glass-bottom boat in summer, which drifts slowly over the lake bed while fish glide past beneath the glass.

The boat does not run in the evening, so if the crossing matters to you, arrive well before dusk. On shore, the park runs an organic trout farm, and Blausee trout is sold in the park's own shop and served in its restaurant, which makes lunch here part of the product rather than an afterthought. Dogs are welcome on a lead, though they are barred from the kitchen, the wellness area and the summer llama pasture.

Blausee AG has run hospitality on this site since 1978, and the operation feels settled and well drilled.

Admission, Hours And The Honest Price Note

Here is the part most guides gloss over. Blausee charges admission, and that charge varies by season and by day of week. Weekends cost more than weekdays, and the operator's own pages do not publish a single stable year-round adult price that could be confirmed in this research run.

The ticket shop lists day admission and evening admission categories, but the figure only appears once you step into checkout. So rather than print a number that may be wrong by the time you read it, check the operator's own ticket shop before you travel. What is fixed is the structure around the price.

Children under 6 enter free, ages 6 to 15 pay a reduced rate, and the park opens 365 days a year, daily from 09:00, typically until about 21:00 with occasional exceptions for private events. That year-round opening is unusual among alpine attractions and makes Blausee the reliable half of this pairing in the off-season.

The Lake And Its World Heritage Status

Oeschinen Lake lies at 1,578 m above the village of Kandersteg. It covers 1.115 km2 and reaches a maximum depth of 56 m, and its basin exists because of prehistoric landslides that dammed the valley. Since 2007 the lake has been part of the Swiss Alps Jungfrau-Aletsch UNESCO World Heritage Site, the same protected area that takes in the Jungfrau massif looming over Lauterbrunnen.

In practical terms that means the setting is largely unbuilt, the water is cold and clear, and the shoreline walks feel like mountain country rather than a park. This is the lake for people who found Blausee too groomed. Give yourself time at the top, because the last stretch from the cable car mountain station to the water is on foot and the whole point is to linger rather than tick the view off a list.

Cable Car Fares, Hours And The Reservation Rule

The Kandersteg-Oeschinensee cable car prices its adult return ticket by season. In winter, covering 22 November 2025 to 8 March 2026, it is US$38.90 (CHF 32). In the spring and autumn shoulder periods, 9 May to 14 June and 22 September to 9 November 2026, it is US$43.70 (CHF 36).

In peak summer, 15 June to 21 September 2026, it is US$48.60 (CHF 40). Holders of a Half Fare Card, GA or Swiss Travel Pass pay roughly half across the same periods, at CHF 16, CHF 18.50 and CHF 22.50 respectively. Children under 6 travel free.

On hours, the autumn window of 21 September to 8 November 2026 runs daily 08:30 to 17:00, and the winter window of 5 December 2026 to 7 March 2027 runs daily 09:00 to 17:00. The rule that catches people out is the online time-slot reservation required for the ascent through 8 November 2026. Book your slot before you board the train in Lauterbrunnen, and remember a reservation does not guarantee a parking space at Kandersteg.

The train ride alone eats a lot of the day, so the sequencing matters more than people expect. This is the shape we would suggest.

If that all feels like too much compression, split them. Blausee opens 365 days a year and works well as an evening or shoulder-season outing on its own, while Oeschinensee deserves a clear day with an early cable car slot. Two shorter trips beat one rushed one, and the second train ticket is the only real cost of slowing down.

Our Interlaken page is useful here, because Interlaken Ost is your first change in either direction and an easy place to break the journey for coffee.
