Hidden Valley (Ski Estes Park)
Hidden Valley, also known as Ski Estes Park, was a ski area near Estes Park, Colorado. It became owned by the National Park Service, which eventually closed it in 1991.
Hidden Valley was a local ski area attraction from 1955 - 1991, off of Trail Ridge Road, now in defunct status.
The National Park Service seemed reluctant about opening it at all, and seemed to have succumbed to local pressure. NPS landscape architect Harold G. Fowler happened to be involved in assessing its feasibility.
