This classic Brighton run is right where the old Evergreen lift used to be, before it was removed in the early 2000's.
Head down Backdoor and stay left as you reach the first main flat area.
You'll see a small gate on your left with a sign that says Exhibition.
Follow this trail to the right.
There are a variety of options in here, with easily navigable trees and small cliffs.
The simplest route is to continue straight down the hill until you link back up with the Easy Out groomer.
