The run, as it is mapped here, begins at the bottom of the Coal Creek trail, with a short section of road running up the shoulder of the highway. While it's technically possible to shuttle this section, it's short and really not too bad. Before you know it, you'll be turning right onto the Pass Creek Trail.

Pass Creek is a popular conduit into the high alpine, beginning from Coal Bank Pass on the Million Dollar Highway. Easily accessible from nearby Durango, on every day of the week, Pass Creek is filled with hikers, mountain bikers, trail runners, and equestrians climbing into the beautiful alpine meadows high above treeline at the top of the trail.

The climb to get above treeline is fairly reasonable, but it still isn't easy: you'll have to gain over 1,000 feet of elevation just to reach the junction with the Engineer Mountain Trail.

Once at the junction with the Engineer Mountain Trail, take a right to run through some more meadows and then another right onto the Coal Creek Trail. From here, you'll still need to do some more climbing before you reach the route's high point on a beautiful alpine ridge. Be sure to savor this view before you begin descending because once you start going down, you'll go down in a hurry!

The Coal Creek descent begins in the alpine, meandering through meadows thick with corn lilies as you descend toward the trees below. After the trail hits the timber, the dirt gets dark and loamy, dropping through a deep, dark pine forest reminiscent of the PNW or the deep pine forests of Montana or Idaho. The beauty of this lush, quiet forest will quiet conversations and leave runners in awe of the rugged beauty of the San Juans.

All good things must come to an end, and soon, you'll pop out above the highway, dropping back down to the pavement. But one thing's for sure: this won't be your last time running Coal Creek!

Note: It is possible to run this loop in the counterclockwise direction, for a steeper climb up Coal Creek and a mellower descent down Pass Creek and the highway.
