Oeschinen Lake

Oeschinen (Oeschinensee) is a mountain lake above the village of Kandersteg in the canton of Bern, set in the Bernese Alps. At 1,578 metres above sea level, its turquoise water framed by steep rock walls is one of the most photographed sights in the Bernese Oberland.

What kind of lake is it?

Oeschinensee covers roughly 1.1 km² and reaches 56 metres at its deepest point. It is an oligotrophic lake, meaning it carries few nutrients, which explains the clarity of the water. Mountain streams feed it, and there is no surface outflow: the water drains away underground. Prehistoric landslides blocked the valley and created the basin. Since 2007 the lake has belonged to the Swiss Alps Jungfrau-Aletsch UNESCO World Heritage Site.

How do you get to Oeschinensee?

Start in Kandersteg, which you can reach by train or car. A gondola lift runs from the village to an upper station, and from there an easy path leads to the shore in a short stroll. If you prefer to walk the whole way, a forest trail climbs from the village; it takes noticeably longer and asks for decent fitness. Many visitors ride up and walk back down to combine both options.

What can you see and do there?

• Walk along the shore and photograph the lake against the cliffs above it.
• Relax on the pebbly beaches or stop at the lakeside mountain restaurants.
• Hire a rowing boat during the summer season.
• Follow longer trails around the lake if you have mountain experience.
• Take prepared winter walks when snow covers the area.

When should you visit?

The most comfortable period runs from late spring to early autumn, when trails are clear of snow and the facilities are open. In summer the water shows its most intense colour, but midday brings crowds, so an early start gives you quieter conditions and better light for photos. In autumn the forests in the valley change colour. Mountain weather shifts quickly, so pack a warm layer and sturdy footwear even on a sunny day.
