St Kitt's has the best and most complete colonial British fort/museum I have even seen. Brimstone Hill Fortress. There is not much beach life to go to on St Kitts so if you are into that sort of thing, its a must. It amazes me to think they built such a huge stone structure way up there on a mountain. The views are incredible too. You can just get off the ship and walk to the right behind the shops at the end of the pier and there is a taxi pick area. You can take a taxi or arrange a "tour guide" Ours took us to the Fort and drove us around to see what sights there are for a good price.
Unfortunately they removed Dominica from this itinerary. That island had some amazing non beach sights.. The twin falls, the steam geysers...
