Nusu - Lombok & Gili Islands

Rio Lajas is a different kind of dive for Costa Rica's Caribbean. It’s a 30-minute boat ride from La Pescadería, and we're talking about a site right at a river mouth. This means the visibility can be a bit challenging, averaging around 4m, so keep your guide close. The bottom is mostly sand, which makes it an excellent spot to really hone your buoyancy control. Don't expect dramatic reefscapes here; instead, keep an eye out for the unusual residents like the Roughbar Frogfish, Oval Flounder, or a Smooth Stargazer peeking out. It's not a site for big pelagics, but if you enjoy macro life and appreciate the quieter, often overlooked species, Rio Lajas offers something genuinely unique.
