7 Things to Do in Buck Island Reef National Monument
Turtle Beach is the western-facing shoreline on Buck Island with calm, blue waters and powdery white sand. It’s among the best beaches in the USVI and, for me, was the highlight of my half-day tour to Buck Island.
🛑 No-Take Zone: You might be tempted to bring home a conch shell souvenir during your trip to Buck Island. However, this is strictly prohibited in the National Monument to protect the ecosystem at large.
Hiking the Buck Island – Diedrich Trail
If you take a full-day tour to Buck Island, you’ll have the option of hiking the Diedrich Trail. The trail takes about 45-minutes to complete ascending through a subtropical forest of native flora to the peak where you’ll be treated to an observation deck with panoramic views of the Caribbean Sea, St. Croix, and on a clear day, St. John and St. Thomas.
Underwater Snorkeling Trail
Before sending snorkelers off, the guided tour to Buck Island will take you along an underwater trail upon arrival. This is their time to assess your snorkel skills while pointing out neat fish and marine life. The underwater trail is found on the barrier reef circling two-thirds of the island.
Swim With Sea Turtles
Like much of St. Croix, Buck Island is a popular sea turtle nesting site with common encounters in the nearby waters. During your time on Turtle Beach, snorkel the sandy bottoms and seagrass beds to witness these majestic creatures.
Buck Island is a critical habitat where endangered brown pelicans and threatened least terns nest. For those interested in birds, whenever my wife and I adventure in the USVI, we always bring this handy Field Guide to Birds of Puerto Rico and the Virgin Islands.
Buck Island has two designated scuba dive moorings on the north side of the island. These are beginner-level dives between 30 and 40 feet. You can contact Caribbean Sea Adventures or Dive Experience for more scuba diving information.
🤿 Wall Dive in Cane Bay: The dives around Buck Island are great, but in my professional dive opinion, you can get a better diving experience directly from the beach at Sweet Bottom Dive Center on Cane Bay Beach.
Have a Picnic
Buck Island has two designated picnic areas with charcoal grills to have your own picnic. Of course, if you’re on a full-day tour, lunch will be provided by the charter company. Either way, enjoy your meal on one of the Caribbean’s best beaches!

Tips for Visiting Buck Island from St. Croix
Book a Full-Day Trip
Half-day trips to Buck Island are great, but to fully enjoy everything the park has to offer, book a full-day tour! You’ll have more time for snorkeling, exploring the beach, drinking rum punch, and embarking on the scenic hiking trail!
Prepare for the Sun
The Caribbean sun is intense and much of a day at Buck Island is spent with no shade. Pack UPF clothing with long sleeves, a hat, sunglasses, and reef-safe mineral sunscreen.
Visit Mid-week or the Offseason
Buck Island isn’t only popular with those visiting St. Croix, but it’s also popular with the locals. On the weekends, Turtle Beach fills up with private boats enjoying the park’s beauty. If you go mid-week, chances are you’ll only have to share the island with other guided tours.
I visited in October during the offseason and had the beach to myself (+ the others on my boat). Not only can you avoid the crowds, but traveling during the offseason is by far the cheapest time to visit the US Virgin Islands!
