Sorry, I don't remember how much we paid for to visit the castle. I don't remember it being very much though. We did it on our own when we first got to St. Thomas. We saw it from the pier and hiked our way up what seemed to be a million steps. Turns out, they offer a free shuttle service up to the castle. We'll know that for next time. We loved walking around the area without having to stay with a tour group. I remember he told us that our admission fee included the use of their pool if we wanted, we however did not use it. The staff was exceptionally nice and they provided a free shuttle back to main area where we could catch a taxi since we were going to Magen's Bay next. We thought it was fun. If I had girls, I would think not so much but it was perfect for pirate loving boys. If you have any more question just let me know here or pm me. I can find some pictures and try to post them.
