Bat Islands
Experience the Thrill of Diving at Bat Islands
If you're seeking an adventurous and unforgettable diving experience, look no further than the legendary Bull Shark dive at the Bat Islands — known locally as Islas Murciélago.
These remote islands are home to a wide variety of marine life found throughout Costa Rica, but divers come here for one reason above all: the chance to encounter the powerful Bull Sharks in their natural habitat — and, with luck, a majestic Giant Manta Ray. This is a true natural shark dive: no feeding, no chumming, just raw, unscripted nature.
Dive Conditions and Requirements
During the summer months, the waters around Bat Islands are often warm, blue, and clear. However, conditions at the site can be challenging, with unpredictable currents that require good buoyancy control and awareness underwater. The dive reaches depths of around 30 meters (100 feet), making it suitable for moderately experienced divers only. For this reason, we require all participants to have recent diving experience and to feel confident and comfortable in the water.
Departure Point
All dive boats to Bat Islands depart from Playa del Coco, the closest launch point to the islands. If you’re not driving yourself, we can assist with transportation — just let us know in advance so we can make arrangements.
