Of course, this is up the mountain from the loop highway, but it is a very interesting spot.
Terry Richard, "Cloud Cap Inn tours on Mount Hood begin in June"
Cloud Cap Inn was built in 1889 to be an elite mountain retreat and is now a search and rescue base for the Hood River Crag Rats, the oldest search and rescue organization in the United States. The Hood River Crag Rats began caring for the structure in 1952 under a special use permit with the Mount Hood National Forest.
