November 26, 2023, Crags Hotel Ruins

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.

Gross Dam Road is a mostly-smooth, hard-packed gravel road that connects Flagstaff Road to Coal Creek Canyon Highway. This scenic road sees very little traffic and there are great marked scenic overlooks along the way. Although the road is generally pretty moderate in grade, there are a few moments of 1‍2-15% gradients to get your heart rate up if ascending the road from Coal Creek Highway.
