The Fox Lair campsites are named for some abandoned facilities nearby, which I did not see but you can research how to visit them.
Rte 8 has plenty of campsites, but there is a concentration of several in this one area. There are a few obvious dirt road turn offs, and some not so obvious turnoffs, so keep your eyes open!
We visited a few sites, and most were small and/or trashy and/or taken. We managed to snag a spot at the very top of a wide open hill. There was a fire ring, and a wide open grassy hilltop. This is definitely the site to seek if you're a star gazer. There were many annoying black biting flies, but a little bugspray went a long way against them. The nearby creek was a 10 minute hike down a hillside, and across a wild, grassy field. There was a pit toilet house in between this site and the one next to it, but when you're at the campsite, you see only a small section of the road, no other campsites in view.
The Siamese Ponds Wilderness trailhead is a 2 minutes drive north. I hiked round-trip to the Pond, almost 12 miles, making for a grueling all day-hike. The swim in the pond was worth it, an oasis after a wild trail. There are also a few primitive campsites along this trail.
