Newly built by SDMBA and a good addition to the PQ area. Multiple fast sections with lots of small bumps to catch air off of. Fun in either direction.

Tight, twisted, punchy ups and downs. Great when you’re legs are fresh. Good all the time.

Not very fun it was super loose and there were many blind corners with no berms and was very overgrown

Would recommend starting at the tunnel/ cobbles and ride clockwise. More fun that way.
We hope you've been enjoying Trailforks!
