The Crags Hotel, also known as the Crags Mountain Resort, was built in 1908 at the top of the canyon. The hotel was a very popular destination. There were 3 ways to get there. The Denver and Salt Lake Railroad, often referred to as Moffat Road, passed just above the hotel. Customers could also rent a car to ride up the Rattlesnake Gulch wagon road. As a last solution, customers could take the inclined railway. In November 1912, after the resort was closed for the season, the hotel caught on fire. Only a few ruins remain.

Wear good boots. Lots of golf ball- sized ball bearings loose rock, but 2 1/2 seasons of the year there are a fair number of small rattlers and they aim at ankles.😳 BUT this is a truly fun route guaranteeing solitude. Paradise!

An epic mountain bike loop near Boulder that can be ridden in both directions. If you ride the loop clockwise you will be rewarded with the best downhills and less technical, but still challenging uphills. Be prepared for fun, but challenging loop including some hike-a-bike sections.
