Ten Mile River Scout Camps is a 12,000-acre Scout Reservation that is home to three traditional Scout summer camps and one Family Camp.  TMR is located in the Sullivan County Catskills in New York State, near Monticello and Narrowsburg. It is about a two-hour drive from the George Washington Bridge.

Wilderness backpacking, canoeing, camping, and adventure. One of the most invigorating, challenging, and memorable experiences that Ten Mile River has to offer, the High Adventure Trek has no equal. TMR has built one of the best trek and 50 Miler programs available, and its unique outpost programs are unrivaled in the North East.
