St. Croix is the biggest US Virgin Island and the one most visitors skip. That's a mistake. While St. Thomas handles the cruise ships and St. John draws the national park crowd, St. Croix quietly offers the best diving in the USVI, two of the Caribbean's most walkable historic towns, a real food scene, and beaches you can have to yourself on a Tuesday.
It's also the only USVI island with flat farmland, a rainforest, and a working rum distillery you can tour. Here's what to do with your time.
Historic Towns
1. Walk the Christiansted Boardwalk
The island's main town is a grid of pastel Danish colonial buildings along the waterfront. The boardwalk runs from Fort Christiansvaern (a bright yellow 18th-century fort, worth the $7 entry) past restaurants, dive shops, and jewelry stores. This is where the energy is — lunch at a waterfront restaurant, then walk the side streets. The scale is intimate: you can cover the whole town center in 20 minutes.
2. Explore Frederiksted
The west-end town is quieter and smaller than Christiansted, but the waterfront is beautiful — especially at sunset. Fort Frederik (free entry) anchors one end, the cruise pier the other. The Frederiksted Pier is also one of the Caribbean's best shore dives (see below). On cruise ship days the town buzzes; otherwise it has a sleepy, welcoming feel.
Beaches
3. Buck Island Beach
The beach on Buck Island — a national monument a mile and a half offshore — is postcard-perfect: white sand, clear water, no development. Getting there requires a boat (half-day catamaran trips run from Christiansted, around $70-90 per person), and the underwater snorkel trail on the reef is one of the best in the Caribbean. This is the marquee St. Croix experience.
4. Cane Bay Beach
A no-frills north shore beach with a bar, a dive shop, and excellent shore snorkeling. The reef starts about 100 yards out, and the famous Cane Bay Wall — a sheer underwater drop-off — is accessible from shore for confident swimmers and divers. The vibe is local and relaxed. No resort, no entrance fee, just beach.
5. Sandy Point Beach
The longest beach in the USVI — over two miles of white sand on the southwestern tip. It's a national wildlife refuge and only open on weekends (Saturday and Sunday, 10 AM to 4 PM). Leatherback sea turtles nest here from March through July. When it's open, you'll likely have long stretches to yourself.
Water Activities
6. Snorkel Buck Island Reef
The underwater snorkel trail at Buck Island Reef National Monument has marked stations where you follow a path through elkhorn coral, sea fans, and schools of blue tang and parrotfish. The water is shallow (6-12 feet) and the visibility is usually excellent. Most half-day boat trips from Christiansted include gear and a beach stop. Book through our tours page.
7. Dive the Frederiksted Pier
One of the Caribbean's top shore dives. The pier pilings are covered in sponges, corals, and macro life — seahorses, frogfish, batfish, and juvenile tropicals hide in every crevice. Night dives here are legendary (octopus, bioluminescence, sleeping turtles). Max depth is about 50 feet. Beginners welcome with a guide from one of the Frederiksted dive shops.
8. Dive Salt River Canyon
The top dive site in the entire USVI. Two underwater walls face each other across a quarter-mile of open blue water — east wall and west wall, both dropping past 100 feet. Black coral, sea fans, reef sharks, eagle rays, and the occasional hammerhead. This is an intermediate-to-advanced dive. Boats depart from Salt River Bay on the north shore.

9. Cruzan Rum Distillery Tour
The only working rum distillery in the USVI, producing rum since 1760. The guided tour walks through the production process — fermentation, distillation, barrel aging — and ends with a tasting of their full lineup. Tours run Monday through Friday and cost about $10. The gift shop prices are lower than anywhere else on the island.
10. Fort Christiansvaern
A bright yellow Danish fort from the 1730s, sitting right on the Christiansted waterfront. It's small but well-preserved — the cannons, dungeon, and officer's quarters give a real sense of colonial Caribbean life. Part of the Christiansted National Historic Site. Combine it with a walk through the adjacent Scale House and Customs House.
11. Estate Whim Museum
A restored 18th-century sugar plantation that shows how sugar (and the enslaved labor that produced it) shaped the island. The great house, windmill tower, and sugar factory are intact. The museum doesn't soften the history — it's an honest, well-presented look at plantation life. About 15 minutes west of Christiansted.
Food and Drink
12. Eat Local at La Reine Chicken Shack
The roadside chicken shacks on St. Croix are the island's real food experience. Rotisserie chicken, johnnycakes, rice and beans, and hot sauce — served on a paper plate, eaten on a plastic chair, and better than anything at the resort. La Reine is the most famous, but you'll find good shacks all along Centerline Road.
13. Christiansted Restaurant Scene
The boardwalk restaurants have improved dramatically in recent years. Savant serves eclectic Caribbean-Thai fusion in a courtyard setting. Rum Runners is the classic waterfront spot for a sunset drink. 40 Strand Eatery does farm-to-table with local ingredients. Dinner for two runs $60-120 depending on how you order.
Nature and Outdoors
14. Hike the Rainforest
The western end of St. Croix has an actual tropical rainforest — the only one in the USVI. The trails through the Caledonia Rainforest and around Creque Dam are shaded, green, and surprisingly lush. No marked trail system like a national park, so ask locally for current conditions or hire a guide. Wear sturdy shoes and bring water.
15. Kayak Salt River Bay
Salt River Bay is a bioluminescent bay — one of only a handful in the Caribbean. Nighttime kayak tours paddle through the mangroves while the water glows blue-green with every stroke. The bay is also where Columbus landed in 1493 (the only documented Columbus landing on what is now US soil). Daytime kayak tours through the mangroves are good for birding and spotting sea turtles.
Practical Tips
Getting there. St. Croix has its own airport (STX) with direct flights from Miami, Atlanta, Charlotte, and San Juan. There's no ferry to St. Thomas — the islands are 40 miles apart. Cape Air and Seaborne Airlines run seaplane and small-plane hops between the islands (about 25 minutes).
Getting around. You need a rental car. St. Croix is 28 miles long and public transportation is limited. Driving is on the left (British-style) in American cars with left-hand steering — it takes about a day to get used to it. Roads are generally good but narrow in spots.
When to visit. December through April is peak season with the best weather and highest prices. Hurricane season runs June through November. The shoulder months (May and early June, late November) offer good weather, lower prices, and fewer crowds. Water visibility for diving and snorkeling is best December through May.
Budget. St. Croix is slightly cheaper than St. Thomas. Rental cars run $40-60 per day. Restaurant meals cost $15-40. Dive trips run $90-140 for a two-tank boat dive. Buck Island snorkel trips are $70-90 for a half day. The biggest expense is accommodation — budget $150-250 per night for a decent hotel or Airbnb.
