Some of the best wildlife watching in the Washington metropolitan area is enjoyed here. From the ½ mile wetland boardwalk trail and observation tower, people have excellent views of beavers, frogs, dragonflies and herons. Huntley Meadows is well known as a prime birding spot, with over 200 species identified in the park.
From US Hwy 1 North, exit Hwy 723 to the left. Turn left into park.
