TTFs on TrailBerm, Drop
A tougher, mostly uphill trail with short, fun descents. Small obstacles and drops, tough switchback climbs, and fast descents make this a good trail to train your endurance on.
Access Info
Entrance and exit are located near the end of Upper Beaver Tracks. There is also a bailout at the intersection with 'Lil Red. Note that this is a one way trail.

Big Beaver is a blast! Punchy climbs and a pretty long trail for BDOS. Cardio required!

I enjoy this trail. If you don't enjoy climbing, you probably will not. It will remind you of your high school PT teacher making you do burpees.

This trail rides really well even on a very wet day.
We hope you've been enjoying Trailforks!
