The spring mentioned above is actually on the next section of Foothills Trail, 1.2 miles south of Ross Pass.

Super fun trail with awesome views and smooth flowy sections. The previous comment about stopping and possibly turning back if you don't want to bike up from North Cottonwood is valid. I linked this to North Cottonwood and then rode back in the road, which added some mileage and diversity to my ride. NC is super technical so you'll have to walk in some spots if you choose not to turn around and go back the way you came. Enjoy!

Would not recommend this as a route from M Rock in season. You will have to walk your bike down the lower section due to the crowds of people hiking the trail. The upper section is much less crowded and secluded.

Very smooth trail through good tree coverage and maybe the best wild flower meadows I've seen. Paintbrush was vibrant and dense. The peak around mile 4 is a good turn around point or break spot if you walk out on the hill with great views of the whole valley and bozeman. The decent to cottonwood is fun, smooth and fast with great views allong the way. Keep in mind how much vert you loose here because you'll have to climb back out. Very fun out and back with just a few little spicy sections that traverse some rock slides but overall very doable and not technical.

Amazing piece of trail. Alpine views. Rode on moto, which trail is more suited to. Best south to north. Gnarly sections with risk. Skills required.

Good sweaty ride from junction of Truman to Top of Middle Cottenwood on dirt bike. Couple tree's down in the switchbacks heading south from Truman. Couple fun hillclimbs, skinny sidehills. Not for beginners.

Descending this (south to north) might qualify as double-black

There's an excellent piped spring at mile 6.8, about 25' to the right of the trail, you really can't miss it. No other water sources the entire length of this trail until Middle Cottonwood Creek.

Great Trail if you like to go on a hike and push your bike. The views are great once at the top before descending into Middle Cottonwood. Then its rocky and rowdy.

There's a fallen tree before the first sharp left.
