We ventured up to Rock Lake campground with our 25’ RV in late September, not sure what to expect. Turns out there are only two primitive sites, fairly well separated from each other. The upper one on the left has an outhouse and several picnic tables. The lower one on the right has none of that, but has lakefront access instead. We only stayed here for a night, but it was my favorite campsite on our trip. The setting is beautiful, and while feeling remote there still is cell coverage.
