Charter a Boat: Tortola is a popular destination for boaters. Newcomers usually opt for a boat with captain and crew. Of course, you can take the wheel and help in the galley if you're so inclined.
Hit the Road: You'll get the real flavor of the still-rural island by heading out in whatever direction you choose. The views are dramatic, and the traffic is light enough to allow for easy driving.
Shop in Road Town: The island's largest community is also home to an eclectic collection of stores selling everything from made-on-the-island arts and crafts to comfortable tropical wear by famous designers.
Hit the Trail: Tortola is home to Sage Mountain National Park, a small but quite nice nature reserve. It's home to several rare and endangered species, as well as some trees that normally grow only in rain forests.
Get Wet: Dive trips to spectacular locations leave from Tortola. If you're not certified to dive, an introductory course can teach you the basics and whet your appetite for more adventures under the sea.
