Important information about visiting Constitution Marsh


The Constitution Marsh Visitor Center will be closed for the season beginning November 1st, 2022.  The Constitution Marsh Audubon Center and Sanctuary trails will continue to be open daily from sunrise to sunset, weather permitting. The public is welcome to visit the Marsh and walk the trail as space allows. Those still interested in visiting our center may call us at 845-265-2601 to make an appointment to come into the building.

No dogs are allowed on the site EXCEPT for an ADA service dogs that provide a specific task that is directly related to a person's disability.  Service animals are working animals, not pets.

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.
