We did an island tour with Thenford Grey Tours, called “The Grand Tour of St Kitts”.  Highlights were the Brimstone Hill Fortress National Park (great views), and Timothy Hill view (very unique view of Atlantic on one side and Caribbean on other side). The beach stop at shipwreck was OK, wasn’t super great. Not much sand area for kids to play, rocky, and lots of grass stuff on the beach. Snorkeled there and it was ok, not great though, and please be careful with those black urchins (spikes) as there’s plenty of them there, to not step on them. Next time we will want to go to a different beach.
