Between St-Jean-de-Luz and Hendaye, the route is shared all the way, sometimes with heavy traffic - as on the way out of St-Jean. The descent into Hendaye takes you right down to the beach and joins a well-surfaced cycle lane which goes past the port and Bay of Chingoudy. The cycle route, which is planned up to Behobie on the Spanish border, currently stops before the marshalling yard and presents several obstacles: steep stope and stairs. Cycle lanes are currently being constructed.
Today the international station and Spanish border are only accessible via the N111, which carries very heavy traffic, so it’s not advisable to tackle the route by bike. If you take the train from the Hendaye-Plage station, this will help you navigate this obstacle.
