The country's undersea world has excellent reef diving, good visibility, warm waters, and marine life offering a wealth of diving experiences around the island. In some areas, you can dive to underwater caves or shipwrecks that have been at the bottom of the sea for hundreds of years.
One of the best dive and snorkeling spots on the island is near Boca Chica. You can choose either shallow or deep water diving, during the months of November to January, when the water on this side of the island is at its calmest, and visibility is at its maximum level.
Enjoy La Caleta Underwater National Park with its well-known wrecks the "Hickory" and "Limon." The "Limon" us a 35 metre tug boat and the famous "Hickory", Bowman's treasure hunting boat, a 40 metre transport freighter, both lying perfectly in 18 metre depth.
The diving around Boca Chica also includes some great cave diving in the Cueava Taína. During the times when the island rose slowly from the sea the retreating water has undermined the less resistant parts of the rocks and created large galleries and tunnels in the affected area. It is a system of grottos following the former coastline of the Dominican Republic millions of years ago. Similar to those found in North Florida and Mexico's Yucatan Peninsula, it features a 90 metres long, winding network of caverns and tunnels with underwater visibility easily exceeding 60 metres.
With an average water temperature of 25-29°C, the Dominican Republic is suitable for diving the whole year.
