Our organization firmly believes that we must actively participate in the preservation of the trail system and parks that we all enjoy.

Many of our members are involved in maintaining various hiking trails throughout the Palisades Interstate Park.  In cooperation with the New York – New Jersey Trail Conference, our club is responsible for over 35 miles of trails in Harriman State Park.

Thendara members are actively involved in monitoring of Native American Heritage Sites located throughout Harriman State Park, Bear Mountain Park and Sterling State Forest.  

A few of our members are involved in bear management studies within the park system.  

If you would like more information or would like to volunteer please contact any Thendara board member.
