Hidden Valley 4-H Camp is incredibly lucky to enjoy a 75-year affiliation with Cornell Cooperative Extension of Schuyler County . Schuyler County 4-H families and volunteers ensured that the property was available for New York State Parks to purchase after the end of the Civilian Conservation Corp program, and since that time Hidden Valley has influenced the lives of several generations of children from a broad geographical area. 4-H Camps are open to all children of 4-H age, not just 4-H members, and they promote the experience of a lifetime. Campers make new friends, develop strong ties to counselor staff, and increase their knowledge of their own capacities and abilities.
