The hotel is located on the south face of Mt Hood in Oregon and is home to a ski resort. The Timberline ski resort operates the longest ski season in all of North America with skiing usually being available all 12 months of the year.
One thing you won't find at the Timberline, however, is a hedge maze. Those scenes were filmed on a sound stage in London. Even still, the hotel is a favorite amongst Shining enthusiasts with room 217 (from the novel, not the film) being one of the most requested rooms on the property.
