Built more than halfway up the southern slope of 11,239-foot Mount Hood between 1936 and 1938, the 70-room ski lodge, hotel and launchpad for hikers, climbers and wildlife viewers was almost entirely hand-built using regional materials — such as stone from the building site and nearby canyons, as well as wood from local forests. While the popular president dedicated the property himself in 1937, less than two decades later it fell into a state of disrepair and was closed. Today, though, it’s again thriving, thanks largely to the family-owned R.L.K. and Company, which began immediate renovations after acquiring a long-term permit to operate the lodge and ski area in 1955, and to the fact that the U.S. Department of the Interior declared Timberline Lodge a National Historic Landmark in 1977. Free guided tours of Timberline Lodge take place during the summer or upon special request of the U.S. Forest Service.
