Surf: In Cahuita, whose national park attracts more trekkers and divers than surfers, the main beachbreak, Playa Negra, occasionally gets good with easy rollers for beginners in small swells at high tides, but it can get overhead and hollow on a NE pulse. There's a fun, low tide, longboarding left off the point in Playa Blanca, which speeds up with size. Environment: Watch out for patches of sharp reef and avoid crowds by heading north up the endlessly long black sand beach.
