St. Kitts has some awesome wreck dives. Most notable is the M.V. River Taw. This dive is unforgettable, where Divemasters are allowed to feed the fish, bringing in some massive creatures. The huge freighter is broken into two pieces, and you can see deep inside the hull.
If you visit the M. V. Corinthian you get the best of both worlds. Known as the Tug, this vessel lies near a reef, so you can see a little bit of everything. Coconut Shallows is a piece of Coconut Tree Reef, an exceptional dive with plenty of marine life to see. You can find moray eels, wrasse, and even turtles.
Between St. Kitts and Nevis you can find Monkey Shoals, a gorgeous coral atoll with a whole square mile of gorgeous reef and shallows to discover.
Fly into Saint Kitts, then take the 45 minute ferry ride to Nevis. Take a taxi to get around either island.
