Annecy vs Lyon

Annecy

Annecy has a humid continental climate with strong alpine influence — warm, sunny summers (daytime 22–28°C, but cool evenings 14–17°C), cold winters with limited valley snow but heavy snow on the surrounding peaks (most ski areas above 1,500m are reliable December–April). The lake creates a "thermal pool" effect that keeps the city slightly warmer than surrounding hills in autumn and slightly cooler in summer. Annual rainfall ~1,150 mm, distributed across the year with a slight summer afternoon-storm peak.

Lyon

Lyon sits at the transition between the continental climate of central France and the Mediterranean influence drifting north from Provence, giving it warm summers, cold winters, and distinct spring and autumn seasons. The city is known for its fog — the "brouillard lyonnais" — which can blanket the Saône and Rhône valleys from October through February, burning off by mid-morning on clear days. Summer heat waves can be intense, while winters occasionally bring snow to the Fourvière hilltop. The best weather comes in May, June, and September.

Annecy

Annecy is small, compact, and largely walkable — the Vieille Ville, lakefront, train station, and Champ de Mars are all within 1.5 km of each other. The Sibra urban bus network covers the suburbs and the lake-shore villages; there is no metro. For lake exploration, the Compagnie des Bateaux ferry network is the equivalent of a "lake bus". Cars are unnecessary in the city itself but useful for the surrounding alpine villages and the Tour de France climbs.

Walkability: Annecy is one of the most walkable medium cities in France — flat, compact, and almost entirely pedestrianised in the historic core. The lakefront promenade extends 5 km along the city shore (with continuous walking and cycling paths) and connects to the Voie Verte for further afield. The only "transit" most visitors really need is the lake ferry for Talloires and the bus for Mont Veyrier.

Lyon

Lyon's public transport network is run by TCL (Transports en Commun Lyonnais) and is one of France's best outside Paris. The network integrates four metro lines, five tram lines, an extensive bus network, and two funicular lines climbing to Fourvière — all on a single unified ticket. The city centre is compact and highly walkable. The Lyon City Card (1-3 days, €29-49) includes unlimited TCL travel plus free entry to many museums.

Walkability: The central Lyon districts — Vieux Lyon, Presqu'île, and the lower slopes of Croix-Rousse — are very walkable. The flat Presqu'île from Perrache to Place des Terreaux is a 20-minute walk. Vieux Lyon's cobbled streets are charming but wear supportive shoes. The Fourvière climb on foot is steep (200m elevation gain) but rewarding — most visitors take the funicular up and walk down.
