Sub-Tropic Adventures is proud to have been helping our customers discover the wonders of our marine environment since 2000. Diving in St Helena's waters have something to offer everyone. Beginners will love our predominately calm sea conditions and seeing our extraordinary marine life.  Experienced divers will enjoy the thrill of caves, night diving, wrecks and seamounts. 

St Helena's volcanic past has created a stunning coastline for divers to enjoy with many caves, archways, sea mounts and reefs. You will be amazed by the sheer abundance of marine life including over 50 species found no where else in the world.

In addition to the plethora of life seen on our reefs St Helena is home to many pelagic species such as Wahoo, Tuna, Dorado, Chilean Devil Rays, Green Turtles and of course Whale sharks. The Chilean Devil Rays (Mobula tarapacana) are always a favourite with divers as they are very curious creatures who often spend time with us playing in our bubbles.

There are eight easily accessible wrecks on the leeward side of the island ranging from the Witte Leeuw sunk in 1613 to The Portzic sunk in 2008. The wrecks are not just fascinating historically, they provide unique marine habitats for an abundance of life. With depths ranging from 10 meters to 35 meters, these wrecks offer experiences for all levels of divers.

Diving on St Helena is very accessible with most dives conducted on the leeward side of the island from our two boats Sea Hawk and Sea Horse.
