Buck Island: St. Croix’s Reef Monument

A mile and a half off St. Croix's north-east coast, Buck Island Reef National Monument is the day trip that requires a boat. Protected in 1961 and expanded in 2001, this preserve is a significant underwater ecosystem, offering an accessible snorkel trail through its reef and a stop at the quiet sands of Turtle Beach. The only way to reach this national monument is on a park-licensed tour boat, departing from either the Christiansted wharf or Green Cay Marina on the East End. Planning your visit for a calm, clear morning is essential, as water visibility is paramount for the experience. Be aware that drones are not permitted anywhere within the monument's boundaries.

The main event on St. Croix is the water, and Buck Island showcases a particular aspect of it. The reef on the island's east side hosts a marked underwater trail, guiding snorkellers across the reef, a different experience from the deep water wall dives off the North Shore. After exploring the reef, tour boats typically make a stop at Turtle Beach on the west side of the island for swimming and relaxation. For those based in Christiansted, the boats are often within walking distance of many accommodations, simplifying the morning's logistics. If your stay is on the East End, the Green Cay Marina provides a direct and convenient departure point, avoiding a cross-island drive.

St. Croix is a car island, with its towns, beaches, and sights spread around its edges, meaning you will likely want a rental. While Christiansted offers the convenience of walking to some Buck Island boats, basing yourself further afield, such as in Frederiksted or on the North Shore, means allowing ample time for the drive. The island's speed limits are low—20 mph in towns and 35 mph on most roads—so journeys take longer than they might on other islands. Centerline Road and the Melvin Evans Highway are the primary routes connecting the island’s ends, but many roads in the hills are narrow and winding, requiring a slower pace. Factor in this travel time when planning your day around a Buck Island excursion.

Buck Island is the one sight on St. Croix not to miss. The clarity of the water on a calm day, and the chance to experience a protected reef firsthand through its dedicated trail, makes the journey worthwhile. To ensure the best possible experience, it is advisable to book your tour ahead, especially during high season. Keep your calmest, clearest morning flexible for this trip; good visibility is key, and one windy morning should not cost you the experience of this particular reef.
