Popular sailing destinations
Where this region's sailors actually drop anchor.
Lake Geneva — Lac Léman
One of Europe's largest alpine lakes — vineyard shores, a serious racing scene and the bise.
Lake Zurich
A long city lake with a harbour in nearly every village and busy summer traffic.
Lake Constance — Bodensee
Switzerland, Germany and Austria on one lake — big open water and harbours all the way round.
Lake Lucerne
Fjord-like arms under steep mountains, where the föhn funnels down the valleys.
Lake Neuchâtel & the Three Lakes
Neuchâtel, Biel and Murten, joined by canals — open water, quiet harbours and notoriously sudden winds.

Cruising Swiss Lakes
Switzerland's lakes look sheltered, but they have a mountain temper: the bise and the joran can turn Lake Geneva or Lake Neuchâtel from glassy to white-capped in minutes, the föhn falls down the valleys of Lucerne and Walensee in violent gusts, and there is no tide to read — only the storm-warning lights around the shore. Depth comes from swisstopo's official swissBATHY3D multibeam survey at 1 m resolution, with harbours and anchorages from community mapping. This region covers twelve lakes: Geneva, Constance, Zurich, Lucerne, Neuchâtel, Biel, Murten, Zug, Thun, Brienz, Walensee and the Swiss basin of Lago Maggiore.

Questions
What do the flashing orange lights on shore mean?
They are storm-warning lights. About 40 flashes a minute is a precautionary warning; about 90 a minute is a storm warning — head for the nearest harbour, and let the chart's depths get you in.
Which lakes are included?
Twelve lakes with full 1 m swissBATHY3D depth: Geneva (Swiss and French shores), Constance, Zurich, Lucerne, Neuchâtel, Biel, Murten, Zug, Thun, Brienz, Walensee and the Swiss basin of Lago Maggiore. Lake Lugano is not included yet.
Does it work on the lake without mobile data?
Yes — fully offline once downloaded, so patchy coverage under the mountains and roaming near the borders don't matter.
