Visas & entry
A guide to La Rochelle recommends a day trip to Île de Ré, just 30 minutes away, where eco tuk-tuks are a genuinely fun and low-effort way to see the island's wildlife, oyster farms, and vineyards without needing to cycle the whole thing yourself. Their budget note: bike rentals in La Rochelle itself run around €15 for the day and cover more than 100 miles of dedicated cycle paths, while the compact, pedestrian-friendly city center means most of the main sights are walkable without needing transport at all.
