Long Island: Take a Hike on Mashomack

In accordance with the Department of Justice’s amended regulation implementing Title III of the 1990 Americans with Disabilities Act (ADA) regarding "Other Power‐Driven Mobility Devices,” Mashomack Preserve has completed an assessment of our public areas and trails. While some types of OPDMDs can be accommodated, there are necessary restrictions on their use. Please download and review the policy prior to your visit.

Get out on the land!  Mashomack Preserve is a museum of life in progress, a sanctuary where the natural cycles of flora, fauna, and ecosystems are allowed to endure free from human interference.  We invite you to visit and explore Mashomack and to experience its unique beauty. 

Five well-marked land trails and a marine water trail offer over 20 miles of varying lengths and difficulty.  A wheelchair-accessible trail is located close to the visitor center, where you will find literature, displays, and a small gift shop.  Volunteers provide guidance and answer questions daily in the summer and on weekends during the rest of the year.  Mashomack also offers nature programs and guided hikes throughout the year.  Download a land trail map and a marine water trail map and start planning your visit!


In order to protect the delicate ecosystems and biodiversity of the Preserve, we ask that you abide by the following rules:

  • Only hiking allowed.  Jogging, bicycling, and horseback riding may disturb flora or fauna and can cause excessive wear on the trails.
  • Remain on marked trails.  Exploration of unmarked areas may result in the disturbance of sensitive species and habitats as well as increased exposure to ticks.
  • No collecting allowed.  Accidental removal of rare specimens could result, diminishing the stability of the ecosystems and the enjoyment of later visitors.
  • No pets allowed.  Domestic animals can disrupt and damage wildlife, and could become lost.
  • Everything carried in must be carried out.  Help keep Mashomack free of litter for habitat protection and your enjoyment.
  • Check yourself periodically for ticks.  Tuck pants into socks, tuck shirts into pants, and button cuffs.  Stay towards the center of roads and trails; avoid brushy, grassy areas.  Use of repellents is not recommended.
  • Take only pictures, leave only footprints.
