Les Lavandes is within 10 minutes of the Atlantic coast & has many types of beaches to suit everyone.

La Cote Sauvage;  Mile upon mile of unspoilt, stunning beaches bordered by beautiful dunes and the Coubre forest.. Watched over by France's second largest lighthouse this part of the Atlantic Coast is ideal for surfing and in high season there are areas marked where lifeguard surveillance is in operation.
A walk over the dune at the Cote Sauvage which gives beautiful extensive views of the coastline.
La Grande Cote:  Just along the coast from La Palmyre this is a more sheltered beach than La Cote Sauvage (perhaps more suitable for families with young children).  Again unspoilt sandy beaches with the forest behind.  You can easily park your car and take a 5 minute stroll through the many paths made through the forest where along the way you can see red squirrels.
La Palmyre:  A lovely, easily accessible beach close to the marina and restaurants.  It is very close to La Palmyre (5 mins walk) and the cycle track runs directly behind the beach.  There is a car park just behind the beach.
Ile de Oleron:  One of the beautiful beaches of the island which is easily reached via a road bridge.
St Palais Sur Mer: The beach is in a sheltered bay backed by restaurants and interesting shops.

There are many other beaches close by including  Vaux-sur-Mer, Ronces-les-Bains and Royan.  Further down the Gironde estuary there are more beaches and covesto explore.
