Important information about visiting Constitution Marsh


Constitution Marsh Audubon Center and Sanctuary trail is open daily from sunrise to sunset. The public is welcome to visit the Marsh and walk the trail as space allows. The Nature Center building is currently closed until further notice due to COVID-19.

No dogs are allowed on the site EXCEPT guide dogs, service dogs, and hearing dogs.

Due to our programming and conservation research, please contact us ahead of time if you plan on having a large, unguided, group visit, or would like to visit outside of our normal hours. This will ensure an enjoyable visit for everyone.

The trail to the marsh is less than a mile in length, and has some moderately steep and rocky sections, so sturdy footwear is required. The hiking trail leads to a boardwalk, built-in-memory of the late sanctuary biologist and warden James P. Rod. There are benches to take in the marsh habitat, its wildlife, and an unmatched view of the surrounding Hudson River Highlands.

Please visit our FAQs page for important information and a safe and enjoyable visit.
