La Xinxa is a small rocky formation that grows from -11 m and is divided in two pinnacles, one of it reaching surface. Both pinnacles rest in a rocky platform between -10 m and -12 m. At the east side, the rocky formation developes into some channels like paths where you can dive thorugh them. Here we can find som red corall, lobsters and octopus.

At the north side, the rocky plataform deeps 4 meters reaching the -14 m and -18 m where a coralligen comminity is leaving. At the east siden the second underwater pinnacle has a tunnel of 4 m large crossing from north to south at -9 m and allow divers to cross it as we observe lots of invertebrates.
