Visitors come to Dominica not only for the world-class diving, but also to explore the island's wealth of eco-activities and unspoiled nature. Extensive geothermal activity can be found above and below sea level on this sparsely populated island nation. Located in the eastern Caribbean between Guadeloupe in the north and Martinique in the south, the island has a rich history and is home to the Morne Trois Pitons National park, the first UNESCO World Heritage Site in the region. The main underwater attractions are not only the spectacular topography but the rich marine life, some of which are rarely seen on other islands. There are plenty of dive sites to explore from shallow coral patches to sharp pinnacle, volcanic vents, vertical walls interspersed with caverns and swim-throughs. Dominica is known as the 'Whale Watching Capital of the Caribbean' and boasts a 95% success rate in spotting whales or dolphins throughout the year.
