Top 5 places to experience Indian Ocean diving

1. Seychelles

The Seychelles remained uninhabited until the late 1700s when it was first claimed by the French. Its trading history can be discovered in sunken wrecks waiting to be explored around the island.

There are over 100 islands that make up the Seychelles, but flying to Victoria-Seychelles airport is the best way to reach the country. From there you can decide if you will explore the shore of the main island Mahe or take boat trips or liveaboards to the smaller islands, each with spectacular tropical wildlife. 

Aldabra is a protected area as part of the UNESCO World Heritage program, home to numerous green and Hawksbill sea turtles, silvertip sharks, potato groupers, and many macro critters. Divers require a permit to visit these waters and there are sites to suit all abilities.
