Easy trail up. Very little tree cover for most of the trail, be careful if it’s hot out.

To answer your question about the jumps, I've done this trail 4 or 5 times and have never seen any of the jumps in the pictures.

Are the photos wrong for this trail or is there actually jumps up there? Curious because you can see the road in one of the photos and theres not a road any where near this trail.

The switchbacks are amazing on a dirtbike! Yield to mountain bikes, you’ll probably find some coming down. Ditto on the PNW comment above. One of my favorites.

Really fun climb on a dirtbike, technical but not overwhelming. There’s a decent climb around a quarter mile in but it’s fairly smooth. Try not to spin out on this part—it’s been rutted out from that.

Trail Mill Canyon
So before you embark on a ride in American Fork Canyon, here's a few things to know:

1. This area is a moto playground. Be prepared for massive ruts, huge acceleration/braking bumps, trails that get tilled up and climbs in spots that are down right sadistic. To these points, the trails are and will continue to be cut in by motos, so they are going to flow and cater to them.

2. For all the reasons above, if it rains, avoid for at least a week after the last day of rain. The lower half is well canopied and very slow to dry. Long, massive mud holes form with all the moisture and they are cupped so bad that you will continually slide off the sides into the center.

3. Many of the trails are very loose in spots. Be prepared to encounter anything from ball-bearing mixed loose surfaces to scree fields to volleyball sized boulders that are usually in the middle of the trail at the most inopportune times.

4. If you go on a weekend, be prepared to pull over semi-regularly for the moto trains. Not saying they do not have a right to be there - you just need to be prepared and off-trail because they can move in a pack pretty fast. Early weekdays may be the lightest for trail traffic.

5. The day fee to ride here is $6 - there is a pay station at the reservoir.

For all of these reasons above, if you have both a moto and a MTB, 11 times out of 10 I would choose to moto these trails. There are so many better trails to ride around this area, and the work that you do to access the good stuff isn't simply worth any of the hassle you deal with. To date, it ranks as one of the worst MTB trail networks I've ridden.

Zero stars as a network of MTB trails, 4 as a network of moto trails.

Not sure what the dude above is talking about, it’s still flown and fast. All of the root sections on the descent are super fun and don’t slow you down at all. I guess if you’re looking for more garbage super smooth machine built trail then you’re let down but this trail is super fun singletrack!

This used to be one of my favorite trails and I rode it often over the last decade when I lived close by. This was my 1st visit in about 5 years. I went up and did the same loop of the Ridge trail to here and was really sad to see how much motor cycles have ripped up this section. It used to be quite flowy and smooth but now is still ride able but lots of ruts, big exposed root and silty, sandy sections. Won't be coming back here for a while

We did it this week with a group of 16-17 year-old boys, anticipating that we would have to walk down most of it, but there were only a few spots requiring dismount. Some spots were muddy; the end of the trail was great fun for boys because it had 3 stream crossings at the end.

Right, this trail starts out great, then suddenly becomes a motorcross dug out rock garden. a couple extended sections you have to hike. But I totally agree, that it is worth the few hikes to get to the upper half. You quickly gain a lot of altitude and riding down Mud Springs and Tibble Fork is way fun.

is this really a double-black? can an intermediate rider climb this without too many dismounts?

I like answering my own questions... It's a tough climb with some super steep and loose sections that I had to hike, but definitely worth doing as a good way to loop with Ridge and Tibble
