Starts out mellow with a few loose turns, then starts to point down the hillside. About a quarter of the way in is where it gets really fun. A few steep turns in a row, followed by a step-down/step-up combo that's super rad at speed. Goes into a "rollercoaster" section a la Indiana Jones, and ends with a steep roll down to Canyon Rim. One of the best trails at LH in my opinion.

Probably my favorite trail in LH. It's steep, fast, loose, it's got drops, rolls, and is just plain fun. Best ridden after it's rains or early season.

UPDATE: Finally cleared every part of this Trail and I have to say it's become a new favorite... okay I didn't clear it with a whole lot of style but I did it! LOL. Overall it's slightly harder than ODB (without taking the right turn crazy doom roll that is) but not as dangerous and the roller coaster at the end is just a riot. Just don't go too fast off the final drop/roll or you might end up in the fence :p
We hope you've been enjoying Trailforks!
