Roca Sucia, Dirty Rock - Caribbean Coast

Tables de Taravao is one of those sites we always recommend if you’re looking for something a bit different. It’s a proper two-part dive. You start on a wall, dropping down to about 27 metres, where we’ve often seen big schools of platax just hanging in the blue, and tuna zipping by. The wall itself is full of little cracks and overhangs, great for poking around. But the real magic happens when you move onto the second section: a vast, flat reef covered in these incredible vaulted troughs. It feels like swimming through an ancient, submerged city, all these strange coral formations lifted up, creating tunnels and hideaways. We always find ourselves peering into every dark nook, spotting morays and a good variety of parrotfish, like the bridled and bicolour. It’s a surprisingly architectural dive, really interesting to explore for intermediate divers who appreciate unusual topography.
