Surf: Arenillas Negras is a wider exposed beachbreak but still scattered with rocks and rarely lines up much more than some short mid tide slides and calmer inside whitewash for the beginners. Just to the south however, is a mental bodyboarding, righthand slab called El Rancio where super-thick, below sea-level tubes explode in SW-W swells up to 12ft and any E wind. Environment: Pollution flows from the commercial sector round here, including the rancid waste from the fish processing factory.
