I love going on the tour of the Fort and hearing the history. If you make it there the first weekend in December there is a Pirate Festival. I also love to go to the beach there in the park. There is excellent snorkling, if the weather is just right there. It is a beautiful beach. There is a snack shop and alcohol is also sold there but has to be kept on the deck. This is almost a must see for me each time I am in Key West. You will want to be at the end of the park at dusk to get picture of the sun setting. There are always lots of boats and it makes beautiful photo opportunitites.
