UPDATE: Snowbird has not taken bikes up the tram since 2019 and according to comment from Snowbird the trail is no longer closed to uphill traffic after 11am. However the posted signage still says it is DH only after 11. Thus, you can treat it as bi-direction but assume that others on the trail will be treating it as DH only because of the signage. Ride up with caution.

The Snowbird tram takes you quickly to the top. Hero types can climb to the top either (A) early in the morning so you reach the top before the upper trail closes to climbing, or (B) by climbing Peruvian Gulch Road, which is a brutal proposition.

TECHNICALLY the trail is a blue, but fatigue takes a toll over the 7+ miles of descent to the bottom (making it a black). "It's all downhill" comments sound reasonable until you ride the trail The trail itself seems to go downhill forever. In the beginning there are some big switchbacks with some small tabletops in between the turns. Next you hit the bowl area, which stays wet for long, so there are typically some kind of lattice woodwork (started out with pallets when it first opened). The second half is a mix of buff singletrack and medium to loose trail with some loose rocky sections, but nothing really steep. The only real feature is a bridge that takes you around a tight and steep turn. There are a few little table tops and lots and lots of very tight berms.

These people year of year continue to ruin the trail for mountain bikers with no regard for us. It’s garbage. Yes we don’t bring you money...

Construction still has the middle section of the trail closed, you can still get down on the gravel road but you miss out on some good trail riding.

      Partially close for construction a few miles down cutting off a mile of it. Otherwise f*ckin sick shred. Will be back.

      Best route is climb the fire roads and descend big mountain. Seeing more people climbing single track all times of the day. Just don’t get agro when people are descending with a bit of speed because the trail is designed with some jumps near berms and turns, they’re not big but you’re not clearing them without some speed, so its definitely still built and maintained as a downhill priority trail.

      Apparently Snowbird is allowing tram access for bikes once again. Does anybody know if the downhill after 11:00 a.m. in place again?

      We hope you've been enjoying Trailforks!
