We stopped by on a Tuesday only to find the visitor center, gift shop, and buildings are open Wednesday thru Sunday. The parking lot and grounds are open until dusk daily and there are paths to walk around the fort and along the water. There is a fishing pier that is open to the public. There were markers throughout the property so that we learned about the fort even though we could not go inside. It's a nice place to walk, picnic, fish, or just relax.
