>>2789924 (OP)The terraced vineyards around Lavaux are about an hour to the east and worth checking out if you’re at all interested in wine; could visit the Chateau de Chillon (one of Switzerland’s nicer castles) and/or the small, pleasant city of Lausanne, en route. Lausanne is by some standards a better city for tourists than Geneva. I actually like Geneva, unlike most Swiss people, but it’s nobody’s idea of an exciting place, and it’s overpriced.
Alternately, the very scenic little French town of Annecy is just over an hour south of Geneva (by rail; it’s well under an hour by car).
