Caught the ferry at the last minute for a short drive over to the island. When you get to the island you take a tram to the front gates of the fort. There you are met by a guy who gives you a brief history of the island, programs available that day, and explains the "soap and water" you must walk through when you exit. We headed up two flights of stairs to the top of the fort for a cannon reinactment. The guy leading it was so nice in explaining what each "soldiers" job was (yes, they are all dressed Union soldiers) and reassuring the little kids who already had their hands over their ears that he would tell them when they needed to cover their ears. Those kids were smart because it was REALLY loud. I can't imagine what it really sounded like in battle with multiple cannons. After, the "soldiers" we're really nice and took pics with people in front of the cannon. Then we wandered the fort- they have various rooms set up as exhibits, a short movie to watch if you wanted, and another tour to join if you also wanted with a "living history" person. This was a personal trip for me as my G,G, Great Grandfather died here as a Confederate prisoner. I was really honored to see it. You used to be able to take another ferry to NewJersey to the cemetary but Hurricane Sandy ruined their dock and they have not rebuilt yet. There were families and couples there and all seemed to find something they liked. There is free water refill for your water bottle and a small gift shop.
