There were private property signs, so I decided to not do this route. The ride to it was nice and many of the roads nearby.

Rode on a gravel bike with wide tires on 6/19/2022. The part just north of the ridgeline is basically singletrack. You have to go through a gate as well. But generally a good gravel climb.
