St Kitts & Nevis, located in the Leeward Islands, is a federal two-island nation in the West Indies It is the smallest nation in the Americas in both area and population.  The smaller state of Nevis, lies about 2 miles (3 km) southeast of Saint Kitts, across a shallow channel called "The Narrows".  Here's the map.

There are loads of new, relatively untouched dive sites. More than 400 ships sank here between 1493 and 1825, but only a dozen or so have been identified to date. The western (Caribbean) side of the island is well protected and visibility off the shores is usually in the 60 - 100 foot range and most dive locations are within an easy boat trip from the shore.

The range of diving includes shallow inshore sites and offshore shoals, some stretching several miles. Between St. Kitts and Nevis is a true coral reef, which allows divers to see many different species of coral.  There is a good range of marine life and a good chance of seeing turtles on many sites and areas with overhangs often house nurse sharks.   On night dives, in particular, operators can almost guarantee you will see sleeping turtles.

• Black Coral Reef - for rare black coral. Ask the divemaster to point it out as it is difficult to recognize underwater.
• River Taw - everybody that dives in St.Kitts dives "the Taw", a 144ft. freighter that went down in 1985, sat perfectly upright on the bottom until 1989 when Hurricane Hugo came through and broke the wreck into two parts.
• M.V. Talata - this is an old freighter that found its demise due to a hurricane in 1983. It rests on a reef and is totally upright and facing east across the harbour. Schools of squirrelfish and yellow tail snapper patrol from bow to stern.

• A yellow fever vaccination certificate is required from travellers over 1 year of age travelling from infected areas.
• Regulators, pressure gauges, and BCs are readily available on the islands. The more exotic underwater props are generally unavailable for rental purposes, so divers are encouraged to bring along their own cameras, strobes, bottom timers, dive computers and gauges. Most dive operators are not equipped to accept credit cards. There is no chamber in St. Kitts or Nevis; however there are chambers nearby in Puerto Rico and St. Croix. [Source: www.geographia.com]
