Visit a Tropical Park: If you like to explore mountainous landscape that still looks like it did when Christopher Columbus first landed, head to Sage Mountain National Park on Tortola. Although it gets only 100 inches of rain a year, the park nevertheless has the appearance of a primeval rain forest.

Ponder the Mystery of the Baths: The most celebrated site on the island of Virgin Gorda is the Baths, on the island's southwest shore, where huge granite rocks are strewn along the beach. Granite is rarely found this far south, so it's been suggested that the rocks were placed here by a race of giants or moved south by some ancient glacier. Most scientists think they were spewed up by volcanic activity. The important thing is not to solve the mystery but to explore the cavelike passages between the rocks and to seek out the hidden pools, which are just right for a quick dip.

Explore Remote Anegada Island: Anegada is easy to miss -- it covers only 15 square Miles and stands only 27 feet above sea level at its highest point. Because of the treacherous coral shelf nearby, more than 300 ships have sunk just offshore. Here's the good news: The entire island is surrounded by white sandy beaches, and the population is only about 250 people, so you can often walk for miles without seeing anyone. You'll feel like a modern Robinson Crusoe.

Exploring Deserted "Treasure Island": Legend has it that tiny Norman Isle, south of Tortola and east of St. John, was the inspiration for Robert Louis Stevenson's Treasure Island. The sea caves on this island are some of best snorkeling spots in the British Virgin Islands. To cut costs, ask three or four other people to rent a sailboat with you to go over for a day's adventure.
