The obvious thing to do in Arcachon is to enjoy the many beaches along the coast line, they are wide with white sand and clear waters and offer stunning views of the oceanic basin, the Cap-Ferret peninsula further down the coast to the Great Dune of Pyla.
A visit to the dune itself is a must - you can spend hours climbing this wonderful natural structure and throwing yourself back down at top speed in the safety of the deep sand. Lined on one side with a forest of pine trees, it is met on the other by the Atlantic Ocean.
Much of the coastline is also backed by a wide promenade, offering 15km of cycle path, so if you feel like stretching your legs then hiring a bike is a lovely way to explore the area and to help with your beach selection. If you feel like tackling a little more then there is a total of 150km circumnavigating the entire basin.
Watersports form a major part of the entertainment available on this stretch of coastline, including sailing, kitesurfing, stand up paddle boarding, dinghy sailing, kayaking and much more. And alongside the various water based activities you can also find golf, tennis, horse riding, kids play parks and a skate park...enough to keep everyone happy.
