Simply one of the best alpine descents in Colorado.

There are several different ways to access this trail, the easiest being from the top of Coal Bank Pass 10,600ft via the Pass Creek trail. This typically is done with a shuttle vehicle at the bottom of the trail or simply hitchhike back up.

Alternatively, you can ride the Colorado Trail from Molas Pass and link up with the EMT. This is a great alpine ride which also is typically done with a shuttle. The best times to hit the EMT is usually early July through September. If approaching from the bottom for an out and back, you can start earlier in the year and turn around when it gets wet/snowy.

This trail is fun and technical at times. The views at the top are amazing.

The first 3 miles are rough and the elevation profile here makes it look smoother than it is. Multiple trail fixes of meh flow. Last 6mi are awesome. 10.2mi — 2h 00m

I rated this trail harshly b/c the top from Coal Creek up to CT is a hell hole and largely unridable going up. The last 1/2 mile to a mile going up is absolutely unridable and even hard to hike up b/c thick bushes. The second to last mile going up is a rutted out abomination. Ruts are often 6in deep or more. No flow what so ever. Take my opinion with a grain of salt, however, as I did not ride down from Coal Creek and my guess is that this is where the good stuff is. Aug 12, 2014

I rode this starting on the pass trail which is a nice easyish climb. The engineer trail is spectaluar in the late spring and early summer. Super flowy with some nice steep sections and wide open fast sections all the way down! Aug 9, 2016
Karl below is right. There is section at the top that is difficult to ride form south to north, super steep, and not rideable. The beginning (from Colorado Trail) is spectacular and some of the narrowest singletrsck I’ve seen. Highly recommend north to south route. Aug 4, 2018
