St Croix is the eastern-most of the American Virgin Islands. In fact, Point Udall at the eastern end of the island is the eastern-most point in the United States. The diving around the island can be quite good, but owing to its position in the path of hurricanes it can be quite seasonal.
Getting to St Croix
Most of the major American carriers offer flights to St Croix from points in the mainland, as well as from other islands in the Caribbean. Mainland flights will land at the international airport on the south side of the island, while seaplane flights from St Thomas touch down in the harbor in Christiansted.
St Croix Accomodations
There are a number dive resorts around the island. Most of them are located around Christiansted on the north-central side of the island. There are also several dive shops in the town, so if you want you could stay almost anywhere in Christiansted and be handy to the docks where dive boats depart. You can see a selection of hotels currently available below.
Another option that puts you much closer to many of the best dive sites is to go with a liveaboard. The Juliet spends winters in St Croix. Week-long voyages depart and return to the pier in Fredericksted, which itself is a fantastic dive site. From here, the ship usually heads north and then east along the north coast, stopping at some of the best dive sites of St Croix.
The Diving
If staying in Christiansted, there are a number of dive sites within about a mile of the harbor. Some of them can be done as shore dives, but most require a boat. Sites along the north shore are generally done as drift dives.
The west end of the island also features some fantastic dive sites, such as Fredericksted Pier and Butler Bay. From the Christiansted area, you'll probably need to drive there rather than go by boat, but it's well worth it for a day's outing. The pier is a great dive, with lots of small critters such as seahorses and frogfish. Butler Bay has several purpose-sunk wrecks to explore, which includes one of the first underwater habitats where men lived on the bottom for several days.
