Gerzensee

Gerzensee is a small pre-Alpine lake in the canton of Bern, Switzerland, just a few minutes' drive from Mühledorf (BE). It sits in the municipality of Gerzensee, in the Bern-Mittelland district, and the village takes its name from the water. Since 1965 the lake and its surroundings have been a cantonal nature reserve.

What is the lake like?

The surface covers about 25 hectares at roughly 603 m above sea level. The deepest point reaches 11 m, and at normal water levels the average depth is around 8.5 m. Reed beds line the shore and a small island lies in the water. Hiking guides describe it as one of the medium-sized lakes of the Swiss foothills, with views toward the Bernese Alps.

What can you do here?

Gerzensee suits a quiet walk and some birdwatching along the reeds. Easy walking and cycling routes link the nearby villages of the Gürbe valley area. Bring binoculars and a camera: early mornings, when mist hangs on the water and the peaks show in the distance, give the best light.

Two practical points. The path does not circle the whole lake, because part of the shoreline is private. And a motorway runs close by, so traffic noise can reach the water's edge.

Why is the lake protected?

A 1965 decision by the Bern cantonal government placed the lake and its setting under protection so the landscape would stay as it is. The reserve has two zones. The inner zone (A) takes in the open water, the reed-covered banks and the island. The outer zone (B) wraps around it on the land side. In practice, stay on the paths, keep out of the reeds and leave the birds undisturbed.

How do you get to Gerzensee?

The lake lies between Bern and Thun, close to the Gürbe valley. By car it is a short drive from Bern. By public transport, travel to nearby Belp or Kirchdorf and continue by regional bus or on foot. Check connections on the SBB journey planner.

When should you visit?

In spring and early summer the reeds are green and birdlife is busiest. Autumn often brings morning mist and the clearest views of the Alps. Winter is calm and nearly empty.
