Google maps will try take you up Black Granite Road but that dead ends. The map will also show you that no road leads to this spot. Take road 285 to road 292. There is a decent road that goes through there. That being said, this is not the best spot up there. It's just where I ended up. There are all kinds of boondocking sites. This is grazing land so there will be gates to go through. Be sure to close them.

Decent T-mobile service. 4G to 5G
