Best trail combo from Mid to Chair 2. is easy to miss. It jets off to the right on top of the 2nd table on...

Upper Twilight Zone is just berms, rollers and these weird circle things. Lower Twilight is a little hairier with one vertical wallride which is easily avoidable, and a second wallride that isn't avoidable on the trail. There is no lip at the bottom of the second wallride, so expect to fall if you don't have speed. You can see a worn use trail people use to avoid this wallride. There is also a big rock in the middle of the trail and everyone I saw had to carry their bike over it. I think there is also a jump towards the end near Chair 2, easily avoidable. Fun trail.
We hope you've been enjoying Trailforks!
