General and travel information

San Sebastian and the whole Basque Country offer the conditions that every surfer wants to find, good wind, waves, and incredible beaches. The different beaches offer options for all levels of expertise. The three main beaches for surfers are Ondarreta, La Concha, and Zurriola.

La Concha is characterized by high tide, the waves have a peak at each end of the beach.

Ondarreta’s main characteristic is its “wall” wave. At high tide, the waves crash against the seawall and generate rebounds that give rise to powerful and hollow waves. These are options that need high tide and are perfect when the rest of the beaches are full of bathers.

Zurriola on the other hand is known for medium or low tides, has a powerful peak that opens right and left for the more experienced but in the middle comes out a long and powerful left perfect for beginners.
