I started at the Greenhorn trailhead and then followed the well maintained path over nice log bridges up the drainage. At the Imperial/Greenhorn intersection, I continued climbing Greehhorn. The trail consisted of smooth singletrack, with a few rocky sections thrown in. None of the climbing was too difficult, as it seemed to give breaks along the way. I passed 4 other riders and 4 hikers and was passed by one motorcycle. I completed the Greenhorn-Imperial loop in 1:15 minutes, which included a short break at the top for views of the Pioneers.
I thought that this trail was similar to Adam's Gulch and Chocolate Gulch.
