Trail Greenhorn to Imperial Gulch
Fantastic flowy single track. Start up Greenhorn and down Imperial. Lots of river crossings on your way up. Trail is a little dusty, but to be expected end of July. The climb is good - could use a switchback or two towards the top - quite a grind at the end of your climb, but manageable. Downhill is super flowy with great turns, long runs where you can get some speed and some fun mild technical spots. Great ride!

Great 10 mile loop 1700 vert. Nice grade to high point with only a few very punchy spots. Great flow to trail head. Dusty at bottom

Trail conditions were good today. A little dry and dusty but not too bad. Rode counter clockwise. Coming down Imperial was fantastic.

Excellent ride. Definetly best to do it as a counter-clockwise loop. Has very nice high speed sections with great turns for carving. Not technical but very fun.

Trail Greenhorn to Imperial Gulch
Mellow climbing grade with some moto whoops and small water crossings through burnt out forest. Multi use trail so there’s also some horse poop in spots. The descent has Epic views, ripping single track, flowery meadows, with some rocky tech spots but nothing too sketchy.

Trail Greenhorn to Imperial Gulch
FYI- this is also a dirt bike trail - hence the 2-4 inches of dusty dirt. Some of it is fun, but I would have to disagree with the PB article from 2018 that labeled this loop as “legendary” ...it’s more meh! Please list that this is also a dirt bike trail and then those who do not want to ride in fine powder can avoid it. This was even in June, after a huge rain storm the evening before last.

Good consistent climb with many creek crossings and an occasional log over the trail. I used it to access Warfield.
