If you're into museums or not, this place is awesome, whether for a day trip or for just a couple of hours. A must see when in London!!

Hands down, the most beautiful beach I've ever visited.  It is quite a ways from Charlotte-Amalie, but worth the trip.  Go to Mountaintop and take in the views. Be cautious of taxi drivers...charge you one price but then want more money once trip is over.  Worth the trouble though, to tour the island.
