    Las Tetas, off Costa Rica’s Caribbean coast, is a site we always try to hit when the conditions align. It’s essentially two rock pinnacles, one bigger, one smaller, breaking the surface and dropping down to about 17 meters. You get a real sense of being offshore here. We usually kick off our dive along the northern rock, keeping an eye out for the resident snowy groupers lurking in the shadows. It's a proper wall dive in parts, with plenty of cracks and crevices to poke around in. We often find Hancock's blennies peering out, and the occasional freckled moray. The sheer number of smaller reef fish can be impressive – schools of snappers and grunts often swirl around the pinnacles, and we’ve seen big pufferfish moseying along. Visibility averages around 11 meters, which isn’t epic, but it’s usually enough to get a good sense of the action unfolding. Keep an eye on the blue for whitetip reef sharks cruising by, and if you’re lucky, a manta ray might ghost past. It’s a site that suits divers comfortable with a bit of current and who appreciate the dramatic topography of offshore pinnacles.
