Free National Forest dispersed camping 9.6 miles west of the far edge of Buffalo on Highway 16. Small sign on right says Grouse Mountain---turn left and there's parking for over a mile alongside the road in the grass. No amenities.
Good news is you're twenty-three hundred feet above the town so cooler weather, also you can see the Telecom towers eight miles away and there's terrific cell service.
Buffalo is a little old mining and railroad town from the 1880s that's only about 4,400 people, 4600 FT elevation. But there's a couple of saloons historic district a few things to see and do.
