La Ocho

beginner

La Ocho sits by Escambron just east of Old San Juan and gives the capital a real longboard reef option. The wave breaks over reef and rock, spreads across a large area, and can suit many ability levels when small. It is not as soft as Pine Grove, but its protected setup, board-rental access, and rolling rights make it a useful longboard and progressing-beginner page when size is manageable.
