Lyon vs Rotterdam

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.

Rotterdam

Temperate maritime climate — mild but grey. Notoriously windy (the port effect). Rain is possible any month. Summer is pleasant but brief; winter is cold and overcast.

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.

Rotterdam

Rotterdam has an excellent RET transit network (metro, tram, bus). OV-chipkaart or contactless card for all transit. The city is also extremely cycle-friendly.

Walkability: Very walkable in the city center; Cube Houses, Markthal, and Erasmus Bridge all within easy walking distance of each other
