The Best Diving in Costa Rica

Bat Islands

If you are looking for a more adventurous diving trip, then you must try the famous Bull Shark dive at Bat Islands or as they are locally known, Islas Murcialego. The site is called The Big Scare and home to Bull Sharks and giant Pacific Manta Rays. Bat Islands is a seasonal dive trip operating from May through to October.

Bat Islands are also home to many species that are found all over Costa Rica but the reason divers are heading to Bat Islands is to see the mighty Bull Sharks and hopefully see a Giant Manta Ray too. This is a natural shark dive and there is no feeding or chumming involved.

During the summer months the water at Bat Islands can be blue, clean and warm. The site reaches around 30m/100ft deep and the conditions call for moderately experienced divers. For this reason we require our divers to have recent diving experience and feel very confident in the water.

Bat Island charters typically run from May to October during the summer fair weather season.
