Avalon Nature Preserve, located in Stony Brook on Long Island’s North Shore, is a protected sanctuary of meadows, forests, wetlands, and trails. Spanning nearly 200 acres, the preserve is dedicated to conservation, environmental education, and outdoor recreation. With its peaceful walking paths, native plant gardens, and wildlife habitats, Avalon provides a serene escape into nature while remaining close to the historic village of Stony Brook.

History

The land that makes up Avalon Nature Preserve was once part of private estates and farmland before being permanently set aside for conservation. Established in the early 2000s by the Paul Simons Foundation, the preserve was created to protect the local ecosystem, restore natural habitats, and provide a community space for environmental education. The name “Avalon” reflects a sense of refuge and tranquility – a nod to the mythical island from Arthurian legend.
