If trying to ride it down all the way from the top, a spotter is strongly recommended. The steep ends at the paved path, with people walking their dogs and biking. Hard to have visibility, specially in spring/summer.
There's a ride around that allows you to start mid-hill. Not as fun, but much safer.

Couple of big trees down across the path.
We hope you've been enjoying Trailforks!
