Thendara Mountain Club is open to adults, eighteen years of age or older, who are interested in the outdoors and who are willing to cooperate with others in the promotion and enjoyment of communal camp living and diverse outdoor activities.

Our club operates Camp Thendara (Camp T-20) under the jurisdiction of the Palisades Interstate Park Commission. The camp gate is situated on Seven Lakes Drive, 1.8 miles north of the Kanawaukee Circle and 2.0 miles south of Tiorati Circle.

In our bulletin you will find a schedule of hosted weekends at Camp Thendara. These include overnight lodging (generally Saturday night) and three meals (dinner, breakfast, pack lunch).

The volunteer host plans and supplies all the food and assigns the work of preparing or cleaning up after meals — at least one chore per person. The costs of the food will be shared and the appropriate day or overnight house fee will be assessed.

As volunteers conduct all our activities, all members are expected to share in necessary tasks and, when qualified, and in the leadership of hikes, trips and camp weekends.

Leaders/hosts are responsible for the safety and comfort of the group. Therefore, cooperation and acceptance of, and appreciation for, the leaders/hosts suggested arrangements and reasonable instructions are expected of all who participate in TMC activities.

The club assumes no responsibility for injuries or damages sustained by anyone using the club’s facilities or engaging in any of its activities. Waiver forms are stored by the registry and are to be signed on the first visit.

Single membership is open to any person over the age of 18.  Family memberships are available, they include parents and children under the age of 18.
