Hidden Valley Ski Area is a ski resort in the St. Louis, Missouri suburb of Wildwood, Missouri.
Tim Boyd bought the Wildwood Golf Course for $250,000 in 1977. In 1982 he converted the hills to a ski resort while maintaining the golf course. The resort would be the first of several resorts throughout the Midwest and Northeast United States he developed or acquired through his company Peak Resorts.
The resort is in the bluffs above the Meramec River. The area is an upscale St. Louis suburb and the resort is Boyd's least profitable. In 2008 Boyd threatened to close the resort after Wildwood officials balked at his plans to create a snow tubing area (which is now in operation) and add an additional 250 parking spaces. Hundreds of supporters were to attend Wildwood town meetings in support of him.
Boyd ultimately entered an agreement to place the ski resort in a conservation easement in exchange for permission to build 80 homes on the golf property (which he has closed).
At the beginning of the 2012-2013 season, Hidden Valley opened two additional runs on an adjacent hill. They dubbed this new area "West Mountain". With this expansion, one additional chair lift was added to allow access to these runs.
The lift elevation is 860 feet. It has a 312 foot vertical drop. It has 3 surface lifts and 4 chair lifts, including 2 fixed quad. There are 8 trails including 3 easy trails.
