At this time, the preserve remains OPEN. We understand the respite that the outdoors provides for you, but we need you to help us remain open during these trying times.


We need  all visitors to do the following:

  • Follow the governor’s order requiring social distancing of at least six feet. We have asked our park rangers to enforce this mandate, so please do your part to keep everyone safe, including yourself.  Many public spaces have been forced to close due a failure to follow this requirement.
  • Please consider following the CDC’s recommendation to wear a face covering while in public places.




The boardwalk entrance is located at 200 Harbor Road, Stony Brook, NY.

Parking is available along Main Street, on Harbor Road, and in the shopping center just past the Preserve on Main Street.


Avalon Nature Preserve is free and open to the public.

Make the most of your visit. Explore our trails through five distinct habitats.
