Lithium mountain bike down hill trail off Teton Pass. Definitely not for beginners! You can't ride up the trail so a car shuttle is required.
The ride you have to take is extremely dangerous. Pictures do not do it justice. Lots of loose rock, big tree root drops. Steep drop on either side of the trail should you wreck. We did a lot of walking our bike down.
Once you hit the trees it is really cool. They have tons of features built into the trail. All features have a good trail going around them if you aren't up for gap jumps and 10 ft drops. I am not but still enjoyed the bottom part. It would be really cool to be there with people that have actual downhill mountain bikes and watch them ride. As it stands, I won't be back unless there are people to watch. Trail is way above my skill level. Due mainly to the steep top section that goes down a knife ridge.
