A US National Park, the Fort is very nice, and is mostly restored. Easily accessible to walk all around. Well worth the three dollar admission. There is a map guided self tour that is given to you as you enter. You could spend as little as an hour and or up to several hours, depending on how long you want to explore. After the fort, there are several nice little cafe/bars within walking distance along the waterfront, with free wi-fi. I also went on a Sunday, and most shops are closed on Sundays here, so the fort was a good choice.
