WELCOME TO THE MARSH SANCTUARY

The Marsh Sanctuary is a 38-acre nature preserve with trails, open space, a community garden, and a commitment to the protection of wildlife.  It is home to the largest freshwater marsh in Westchester County. It also provides a critical link to the Bedford Greenbelt of conservancies that includes the Mianus River Preserve, Westmoreland Sanctuary, Butler Nature Conservancy, Merestead, the Eugene and Agnes Meyer Preserve and Leonard Park.
​
The Sanctuary is open to the public from dawn to dusk 365 days a year, free of charge. We hope you will bring your friends and family to enjoy a nature walk on our hiking trails or relax in our open meadow.

Support Open Space Preservation

​A healthy open space does not maintain itself—quite the opposite! The stewardship of our beautiful 38-acre Marsh Sanctuary requires commitment, energy, love, and financial resources to protect, maintain, and enhance it—for you, our community. 

As we close 2025, please consider a gift to our Annual Appeal. Every dollar raised goes directly toward the preservation and restoration of Marsh Sanctuary. 

We are deeply grateful for your continued support.
