400km along the Atlantic Ocean
From Royan, head south, starting with the river crossing of the Gironde estuary. Flirt with the many beaches that will punctuate your trip, then join the cycle paths of the Landes that meander between lakes and forests. Swimming will always be within reach of the wheels if you feel like it. Finish your trip by reaching the capital of the Basque Country and touch the Spanish border in Hendaye.
