Hermance

Highlight • Settlement

Nestled between Lake Geneva and the Hermance river, this small village has kept everything of its old character. A real pleasure to stroll in its small alleys, to admire its flowered windows, and to enjoy its beach which offers superb views of Lake Geneva and the villages on the opposite shore.
