With a history reaching back to the Ice Ages, the Thousand Acre Swamp in Penfield is full of unique habitats ranging from marshy lowlands to forested upland tracts.

An extensive boardwalk and trail system winds through the preserve, allowing visitors to observe a unique variety of plants and wildlife. The swamp is one of Monroe County's largest wetland systems and plays a particularly vital role due to its location and immense biological diversity.  




A remarkable variety of animal wildlife, including some rare or unusual species, call Thousand Acre Swamp home. You may see foxes, white-tailed deer, weasels, and coyotes.

Thousand Acre Swamp is managed by an active group of volunteers—the Thousand Acre Swamp Preservation Committee—that manages the preserve, coordinates all public hikes and provides overall guidance and direction to our conservation efforts. Ten trails on the property show you a world of wildflowers, animals, birds and other natural wonders. Join us for more than 30 different professionally guided hikes and field trips every year.
