With two-thirds of the island designated as National Park, St. John is the most undeveloped, easygoing and laid back of the three major U.S. Virgin Islands. There are only two major resorts on the island, and the beaches are unspoiled by large hotels or development.
The main industry here is tourism, and there is plenty to do on St. John, despite its small size – just 28 square miles. A nature lover will have no problem keeping busy on St. John. The island offers many different hiking trails, including easy trails for inexperienced hikers or families with young children, to challenging trails for the avid hiker.
Snorkeling is also a favorite activity on St. John. Several of the island's beautiful beaches boast reefs teeming with colorful fish and underwater wildlife. Venture out on your own, or take advantage of a guided snorkeling tour.
