Camp Greentop Recreation Hall
Camp Greentop Recreation Hall


Completed in 1938 by the Works Progress Administration, is listed on the National Register of historic Places as a Historic District. During construction, considerations were made to make the camp accessible for all to enjoy. Camp Greentop was among the first facilities in the United States to be built accessible. During World War II, Camp Greentop was used by the Office of Strategic Services (OSS), predecessor to the Central Intelligence Agency (CIA), to train Special Operations (SO), Secret Intelligence (SI) and Operational Groups (OG). Today, this cabin camp facility can be rented by organized groups of 60 up to 140 persons. The Dining Hall and Recreation Hall are available for conferences year round. Applications for the entire year will be accepted starting on December 1.
