Diving and Snorkeling

At Buck Island, a short boat ride from Christiansted or Green Cay Marina, the reef is so nice that it's been named a national monument. You can dive right off the beach at Cane Bay, which has a spectacular drop-off called the Cane Bay Wall. Dive operators also do boat trips along the Wall, usually leaving from Salt River or Christiansted. Frederiksted Pier is home to a colony of sea horses, creatures seldom seen in the waters of the Virgin Islands. At Green Cay, just outside Green Cay Marina in the East End, you can see colorful fish swimming around the reefs and rocks. Two exceptional North Shore sites are North Star and Salt River, which you can reach only by boat. At Salt River you can float downward through a canyon filled with colorful fish and coral.

The island's dive shops take you out for one- or two-tank dives. Plan to pay about $70 for a one-tank dive and $95 for a two-tank dive, including equipment and an underwater tour. All companies offer certification and introductory courses called resort dives.

Which dive outfit you pick usually depends on where you're staying. Your hotel may have one on-site. If so, you're just a short stroll away from the dock. If not, other companies are close by. Where the dive boat goes on a particular day depends on the weather, but in any case, all St. Croix's dive sites are special. All shops are affiliated with PADI, the Professional Association of Diving Instructors.
