5 Underwater Volcano Recommendations For Scuba Divers

Volcanoes are one of the planet’s natural beauties, but when most people think of volcanoes they likely picture mountainous formations spewing hot, molten lava. The fact is, many of the world’s most impressive volcanoes are actually located below the surface of the ocean. Some are so deep that only a handful of humans have ever laid eyes on them, but many are easily accessible to scuba divers. Here are some of the best underwater volcanoes for scuba divers.

Barren Island

Andaman Islands

This beautiful volcano is located in the Andaman Sea and provides underwater fields of black sand, lava rock, and gorgeous coral formations. Divers can explore a number of famous locations, including Manta Point and Purple Haze

Batu Tara Volcano


Batu Tara offers some amazing sights both above and below the water. You can see plenty of smoke and lava bursts from the mouth of the volcano, above the water. Dive under the water, though, and you’ll find a multitude of fish and coral. Some of the marine life is pretty unique, like mimic octopuses and frogfish.

Mahengetang Banua Wuhu


The peak of the Banua Wuhu volcano is located about twenty feet below the surface of the water, and you can actually see geothermal gas bubbling up from the mouth. The water temperature around the mouth of the volcano hangs around 100 degrees, making for a truly unique diving experience.

Molokini Crater


The Molokini Crater is one of the most popular dive and snorkel locations in all of Hawaii. The northern side of the crater helped create a crescent-shaped stretch of water that’s home to some pretty amazing reefs that drop off to a 300-foot deep wall on the backside. While the reefs provide plenty of tropical fish to check out, it’s the deep water at the back that will offer some views of some pretty amazing species like manta rays and humpback whales.

Garove Island

Papua New Guinea

The volcano on Garove Island forms an almost perfect circle, the center of which is almost 1,000 feet underwater. The caldera of the Garove Island volcano has a black sand bottom that’s home to a plethora of unique sea life, giving divers some pretty unique underwater photography options.
