Geneva rewards a short stay if you stick to its highlights. The Jet d'Eau Fountain is the citys signature landmark, its towering plume visible from nearly every waterfront point, while the Old Town (Vieille Ville) rewards a slow wander with cobbled lanes leading up to the Cathédrale Saint-Pierre and sweeping lake views from its towers. History lovers should not skip the International Red Cross and Red Crescent Museum, a sobering and well-curated look at humanitarian work born in this city. For a half-day escape, Chamonix in the Mont-Blanc Valley is an easy train ride away. Together these picks balance lakeside icons, old-world charm, and an alpine detour.
