Sirenas Diving Costa Rica is located in the Playas del Coco / Playa Hermosa area of Guanacaste, Costa Rica, a thirty minute drive from Liberia International Airport (LIR). We do not have a physical office; our office is on the internet and on the boat. Our boat is located in the Playas del Coco bay. We have a long-term affiliation with PADI and more than twenty years diving and fishing in the Gulf of Papagayo. Our location puts us in the heart of some of the best diving and fishing in the Gulf of Papagayo, including the Catalinas and Bat Islands (Islas Murcielagos).
