WHY DIVE THE MURCIÉLAGO ISLANDS?
One of Costa Rica’s Most Exciting Diving Destinations

Big Pelagic Marine Life

WHAT OUR DIVERS SAY
"I did 3 dives with Marco at the Murciélago Islands and everything was perfect. Marco is very kind and professional, both in and out of the water. If you're visiting the area, don’t hesitate to contact him for an amazing diving experience!"
David Hodges
"We encountered breathtaking sea life, including large bull sharks, active octopuses, and massive schools of fish... Our favorite dive was definitely at Bat Island an absolute highlight!
"Insanely cool dives (2 bull shark dives, 1 reef wall) at the Bat Islands. Marco is the coolest, most relatable dive master I’ve ever worked with on my 20+ excursions around the globe. Recommend 100%"
