The Basque coast is famous for its long sandy beaches and Biarritz, Anglet and Guethary all offer excellent surfing.
AN EXPERIENCED SURFERS VIEW
"The beach at Cotes de Basque (just south of the main beach in Biarritz) is great fun. The break is huge (as in spread out) with lots of different take off points and plenty of room to spread out and have a wave to yourself. This is primarily a longboard break and is far roomier than the crowded shortboard beach breaks in the area - much more mellow.
Avoid high tide (the waves come above the steps and access is a bit tricky) but a falling and rising tide still works. Lots of lefts and rights - stuff for beginners and more experienced surfers.
There is a board shop on the beach with a surf school. Otherwise the Quicksilver shop on the main beach does sensible rentals (including some glass boards).
Just a word of caution - parking is tricky - either go first thing or get someone to drop you off and pick up.)"
The local beaches include:-
BIARRITZ - There are 2 sandy beaches in the centre of Biarritz, the most notable is 'Grand Plage' which is great for families and surfers and has lifeguards in the summer. It is directly in front of the Art Deco Casino and surrounded by restaurants and shops. 'Plage de Port Vieux' is a sheltered cove perfect for swimming away from the surfers. Milady Plage and Ibarritz are also very close.
ST JEAN DE LUZ - lovely sheltered beach in a bay - ideal for babies/young children.
ANGLET - Long sandy beach - often empty even in August. (Park towards the end of town).
BIDART - A fine sandy beach. It has waves and rock pooling.
CIBOURE - Perfect beach for young children. Also good for Sailing and Watersports.
