Virgin Islands National Park

Virgin Islands National Park covers 14,689 acres on the island of St. John — about two-thirds of its land — plus a submerged buffer of coral reef extending 0.25 miles offshore. St. John is the smallest of the three main U.S. Virgin Islands and has no commercial airport; visitors fly to St. Thomas and take a 20-minute ferry from Red Hook to Cruz Bay, where the park visitor center is located. The park protects coral reef, tropical dry forest, mangroves, and plantation ruins across a rugged, hilly landscape that reaches about 1,277 feet at Bordeaux Mountain. Entry is free, and the park ranks 50th in annual visitation among the 63 U.S. national parks, drawing roughly 374,000 visitors per year. Trunk Bay, Cinnamon Bay, and Maho Bay are the park's main beach areas, each accessible by car or taxi from Cruz Bay.

The park is best known for Trunk Bay, consistently listed among the top beaches in the Caribbean, where a 225-yard underwater snorkel trail runs along a coral reef with labeled features visible through the water. The Reef Bay Trail descends through tropical forest to the ruins of a 19th-century sugar estate and, along the way, passes a freshwater pool with Taino petroglyphs carved into the rocks — the most accessible Indigenous rock art site in the U.S. Virgin Islands. Cinnamon Bay holds the park's only campground, one of the most popular beach camping destinations in the National Park System. Sea turtles nest on several park beaches from May through October.

St. John has no commercial airport. The only way to reach the island is by ferry from St. Thomas. Fly into Cyril E. King Airport (STT) on St. Thomas, then take a taxi or local transport to either Red Hook (east end of St. Thomas) or Charlotte Amalie (the capital). Ferries from Red Hook to Cruz Bay take about 20 minutes and run frequently throughout the day. Ferries from Charlotte Amalie to Cruz Bay take about 45 minutes and run less often. Ferry tickets are purchased at the dock; no advance reservations are needed for the passenger ferry.

On St. John: Cruz Bay is the main town and the park visitor center is steps from the ferry dock. Rental cars (mostly open-air 4WDs), taxis, and shared safari buses serve the island. The North Shore Road passes all major park beaches; Centerline Road crosses the island east–west. Traffic drives on the left. Most park beaches are reachable in 15–30 minutes from Cruz Bay by car; parking at Trunk Bay fills early on busy days.

Practical note: Vehicle rentals on St. John are limited and demand exceeds supply in the high season. Reserve a car before you arrive if driving is part of your plan. Taxis and safari buses are a practical alternative for beach days.

St. John sits on a block of Cretaceous-age volcanic and sedimentary rock, roughly 100 million years old, associated with subduction of the Caribbean Plate. The island's hills — reaching 1,277 feet at Bordeaux Mountain — are composed primarily of andesitic volcanic rock and marine sedimentary layers that were folded and tilted as the plate boundary shifted over millions of years.

During the last ice age, sea levels were roughly 300 feet lower than today, and the entire Virgin Islands bank was dry land connected to Puerto Rico. When ice sheets melted and sea levels rose over the past 15,000 years, the valleys between the hills flooded to form the bays, coves, and channels that define the island's current shape. The shallow underwater platform surrounding St. John — now protected within the park's submerged lands — is the same rock bench that was once dry coastal plain.

The fringing coral reefs that line much of the park's coastline built up over the past several thousand years on this submerged volcanic rock foundation. Staghorn and elkhorn corals historically dominated the shallower zones; disease and warming ocean temperatures since the 1980s have killed much of this coral, and the current reef is dominated by brain corals, star corals, and gorgonians. Periodic bleaching events, including severe episodes in 2005 and 2015, continue to affect reef health.

Green sea turtles and hawksbill sea turtles are the most visible large wildlife in the park. Both species nest on St. John beaches from May through October, with Trunk Bay and Cinnamon Bay among the most active nesting sites. Turtles are commonly seen feeding on sea grass in shallow bays and grazing on algae near the snorkel trail at Trunk Bay. NPS rangers monitor nests and ask visitors to stay off beaches after dark during nesting season.

The reef fish community includes queen angelfish, blue tang, parrotfish, sergeant major, spotted eagle rays, and — with luck — nurse sharks resting on the sandy bottom. Hawksbill turtles feed on sea sponges in slightly deeper water around Waterlemon Cay. West Indian manatees pass through the area occasionally, most commonly in winter months.

Shorebirds and wading birds concentrate at Francis Bay Pond. Black-necked stilts, white-cheeked pintails, great blue herons, tricolored herons, and black-crowned night herons are regular residents. Magnificent frigatebirds soar above the coastline year-round; brown boobies and brown pelicans dive for fish offshore. The introduced small Indian mongoose, brought to St. John in the 19th century to control fer-de-lance snakes, is now widespread and has severely reduced ground-nesting bird populations across the island.

The Ciboney and, later, the Taino (Arawak) people inhabited St. John for centuries before European contact. The petroglyphs visible along the Reef Bay Trail — carved into the rocks beside a freshwater pool — are among the few surviving examples of pre-Columbian Taino imagery in the U.S. Virgin Islands, depicting human faces and geometric symbols whose precise meaning is not fully understood.

Christopher Columbus sailed through the Virgin Islands on his second voyage in 1493, naming the chain Las Once Mil Virgenes. The Dutch and English contested the island in the early colonial period before Denmark formally claimed St. John in 1718 and encouraged plantation settlement. By the mid-18th century, dozens of sugar estates covered the island, worked by enslaved Africans transported across the Atlantic. The Annaberg Plantation, whose ruins stand in the north of the park, operated from the early 1700s until the 1830s.

On November 23, 1733, enslaved people on St. John launched a coordinated uprising — one of the largest slave revolts in the Caribbean — seizing control of the island for more than six months. Danish colonial forces and French troops from Martinique finally suppressed the rebellion in May 1734. The event is commemorated today as a defining moment in Virgin Islands history.

Denmark sold the Danish West Indies to the United States in 1917 for $25 million, primarily for strategic reasons during World War I. In 1956, philanthropist Laurance Rockefeller donated approximately 5,000 acres of land he had purchased on St. John to the federal government. Congress established Virgin Islands National Park on August 2, 1956. The park was expanded in 1962 to include the offshore coral reef environment.
