Even if you're not in the market for a tee shirt, a St. Thomas souvenir or a banana daiquiri, a stop at this touristy attraction is worth it just for the view. At 1,500 feet above sea level, visitors can see up and down the island chain. The area, once known as Signal Hill, served as a strategic communications point for the United States government during the 1940s. Tour buses galore visit this spot, so time your visit when only a few cruise ships are in the harbor. There is no admission charge.
