There is a nice (and easy) 3/4 mile walking trail along the water. There are picnic benches and plenty of free parking. A short movie can be seen inside the office building which also houses a book store, displays, and the rest room facilities. The staff was very friendly and pets are welcome - we saw about 6 dogs. We visited on a weekday so there was no reenactment. Plan on spending about one hour to see everything (or just relax and watch the water)!! Also check the botanical gardens (another thread) which is also free and several miles away.
