hmmm, there are many rocks in costa I've had the opportunity to skirt by, land on, and get uncomfortable with. Above and below the water Matapalo, Pavones, Cabo Blanco, Roca Loca, Dominicalito, Hermosa near the north end (big rock), Playa Negra, Little Hawaii, Avellanas south end (and the other reef waay out that not many people go to), Avellanas at the boca (rolled over that one a few times), and salsa brava for the east coasters. Oddly enough, it was multiple wave hold downs at Tulin that really got me almost drowned.
