Diving day and night, in sandy, rocky or mixed seabeds, in caves or shipwrecks… The Sao Tomé Islands offers adequate spots for various experience levels, from beginners to professionals, and the adventure may start with simple snorkelling in order to leisurely enjoy the abundant marine life of the archipelago’s crystal clear waters. Given the islands privileged location virtually on the Greenwich meridian and right on the Equator, it's offer ideal conditions in terms of visibility and water temperature to underwater sport.

The reefs are made largely of hard corals and interesting rock formations. A large variety of marine life exists including bright red soldiers, snapper, goat fish, barracuda, turtles, eels, lazy nurse sharks, stony coral, gorgonian sea fans and volcanic boulders coated in anemone like hard corals of vibrant orange/red and yellow colours.

The small islet, Ilhéu das Rolas, offers the spectacular dive resort named Pestana Equador. Another famous dive spot in Sao Tomé island is at Lagoa Azul or Blue Lagoon.

Snorkeling and fishing are very popular and the key attractions on the smaller island of Principe as there is a lot of volcanic rock and hard coral in the water, bountiful fish and water is warm all year round.

The most popular dive sites on Principe island are: Bom Bom Resort, Pedra de Adalio, Pedra de Galle, Maria Coreo, Jockey Cap Island and Shark Dive.

Bom Bom Resort has a shore dive for beginners - snapper, octopus and angelfish can be seen as you swim through an underwater arch.

Pedra de Adalio is a reef dive west of Bom Bom which you reach by boat, and has octopus, eel, groupers and sturgeons.

Pedra de Galle is a deep dive to 30 metres that challenges divers as it goes down a sheer rock face teeming with trigger fish, snapper and barracuda.

Maria Coreo is again to 30 metres and is only suitable for advanced divers. There are many reef fish here, along with moray eels, turtles and nurse sharks.

Jockey Cap Island has a diver of 24 m with large schools of small fish, barracuda, parrot fish, trigger fish and sometimes turtles.

Many the reefs lie at 10m but deep dives to 30 plus metres are possible. During Feb and Mar, storms occasionally churn the sea making diving unpleasant. During the rainy seasons the diving can still be good. In Jun and Jul the sea is slightly choppy while the sunniest period is from Nov to end Mar. Scuba diving is not recommended from March to mid May due to the rivers emptying into the sea.
