About Us

Small operation.
Serious about the water.
Sirenas Adventures Costa Rica is a small, owner-operated diving and adventures shop based in Playas del Coco, Guanacaste. No tourist buses, no crowded boats. Just you, the Pacific, and guides who know every reef, current, and fishing spot in the Gulf of Papagayo.
Our team brings over 30 years of diving and instruction experience right here in Costa Rica. Our instructors are former medical professionals and educators — a unique combination that means safety and quality instruction come first, every single time.
Our goal is simple: to offer the best fishing, diving, and snorkeling experience possible, providing personalized excursions to our customers and friends from around the world.
How we operate.

Customized for You
No cookie-cutter tours. Every trip is tailored to your group, your interests, and your skill level. Small, personalized, flexible — including afternoon departures.
