“A great trail that takes you right into the heart of a biologically diverse marsh wetland habitat.”— Rafi Wilkinson
The trail may be muddy or slippery. Wear adequate footwear. The trail length from the south parking lot around the eastern loop, to the observation deck and back to the south parking lot is 1.7 miles.
A handicap parking spot is provided at the north lot. There is a paved road from this lot to the accessible overlook.
The diversity of plants, birds and habitats signifies the return of a healthy wetland ecosystem after decades of neglect. Now restored, the Great Marsh's fens, sedge meadows and wet prairies are again thriving and providing the natural filter to improve the area's water quality.
