We heard about the Blue Hole, and decided to go see what it was. We found the park first, and thought that was it, but then discovered it on down the road. It was totally amazing! We didn't go in, but we watched people dive. Next time we'll make sure we go in! It isn't very big, 80 feet across, I think. But it is deep, and there are caverns beyond it. And it is very cold. Very inviting!
