Catherines Pass Trail  at Albion Basin
The Catherines Pass trail is not something the typical mountain biker will want to do. It's very steep with technical sections and more than a little hiking with your bike as baggage. It's reserved for tough and skilled riders looking for a challenge. It can be done as an up-and-back trip to the viewpoint, but is primarily used to access the Great Western Trail for long brutal trips by adventurous souls. The direct route has 2.1 miles of dirt road and 1.4 miles of tough singletrack, climbing to 11000 feet.

Getting there:
From I-15, take the 90th South exit and drive east towards the mountains. This will take you directly to Little Cottonwood. When you arrive at the stop sign in the canyon, with the giant illuminated Little Cottonwood conditions sign on your right, turn right uphill and drive 8 miles to Alta. Keep straight until the end of the road. Park on the right side of the road just before the information booth (the booth is between the lanes of the road just before it turns to gravel).

Trail conditions, connections, and alignments will change. Use this guide at your own risk
