72 km long, 13 km wide, 300 m deep: Lake Geneva appeared 15,000 years ago, after the retreat of the Rhône glacier. 140 professional fishermen bring out 650 tons of fish a year (whitefish, perch, pike, trout, arctic char), and some of the world's most important regattas on enclosed waters take place here every year: Cinq Jours du Léman, Bol d'Or in June, Translémanique en solitaire in September.

You'll sail along the lake for most of this magnificent circuit, with a stop at Corzent beach. After climbing back up to Anthy, you'll be back on the water's edge at Redon beach. To get to the next beach at Excennevex, you'll need to cross Sciez and ride very carefully along the N5 for 1.5 km. Allow time for a visit to Yvoire and the charming little port of Nernier. You can also visit the Collongette farm museum after Chens-sur-Léman. Take care on the short, traffic-light-protected drive through Douvaine, and on the way back to Sciez, don't miss the right-hand hairpin bend just a few metres from the main road, and the sudden changes of direction over the next 3 km. After Anthy, return to Thonon following in your footsteps.
