This small state forest campground in north/central Massachusetts is just up the hill from Damon Pond. I suggest downloading maps before you head out because cell service is iffy in the area.  

Sites are largely level, around a small, bisected loop with towering pines. Most of the sites are best suited to tents and small trailers (think teardrops and pop-ups), but a couple of sites can accommodate slightly larger units. They are level and there's not a lot of brush between sites, so not much privacy either. I liked site 3 for a bit more privacy ; it's also one of the 3 sites designated for an RV. Site 11 is larger and can accommodate a larger unit.

There is a large yurt suitable for 10 people. The yurt does offer electricity, but there are no hookups nor a dump station at the campground. There are flush toilets, but no showers. The small bathroom was under renovation autumn 2020. There is a dishwashing sink. 

There are hiking trails in the area and, of course, swimming at the small pond. A nearby roadside waterfall offers another picnic area opportunity. For a longer hike, you can hike to and from Pearl Lake State Park. Fishing, mountain biking, and geocaching are other activities available. There's a parking lot closer to the beach or it's an easy walk from the campground.

If you are from out of state, check fees carefully. In 2020 MA increased fees significantly in light of the pandemic. Prices are steep for what you get if you are out of state.
