14 miles long & three miles across, St. Thomas has the largest population of the US Virgin Islands. Its deep water harbor makes it a popular cruise port. Of the 40 beaches, Megan's Bay is most famous, but all bustle with watersports and yachting activity. Mostly US in custom, driving still follows the British way, on the left hand side of the road. Charlotte Amalia is the capital, its scenic harbor nestled amongst hills.
