Skip the tourist buses and crowded boats. Sirenas offers small-group, personalized diving in the Gulf of Papagayo with 30+ years of local knowledge — from manta rays at the Catalinas to bull sharks at the Bat Islands.
Sirenas Adventures is a small, owner-operated diving and fishing shop based in Playas del Coco on the Gulf of Papagayo. The team brings over 30 years of local experience to their personalized excursions, with instructors who are former medical professionals and educators. Their dive trips run from local reef sites just 10-20 minutes by boat, as well as longer charters to the Catalina Islands (30-40 min) for manta rays and the Bat Islands (60-90 min) for bull sharks. Local dives depart at 8:30am with two tanks included, while night diving is available before sunset. Beyond scuba, Sirenas offers sport fishing charters targeting marlin, sailfish, roosterfish, and dorado in the Gulf of Papagayo.
