Very fairly priced, the beach and kayaking on the calm lake is always the highlight of my stay. There are plenty of things to do with younger or older children, including a big park on the lake. I have never had a bad experience here, so nothing to complain about.

Newly renovated statecpark. Spacious tent and RV sites. Beautiful beach area with the possibility of non-motorized water sports. Great for families.

Stayed in September 2025 during the off-season, which meant very few people around—a big plus. Check-in staff were friendly and welcoming. The beach and swimming area were excellent, and the park had some great bike rides. Everything was very quiet, with plenty of space between campsites—much better than the packed, commercial-style campgrounds. We didn’t bring our dogs this trip, but agreed it would be a fantastic spot for them since the sites are so spread out. We would definitely stay again. A note for anyone with a fifth wheel: at site 87 you’ll need to pull all the way into 88 to get in, or else back down the road. I recommend walking the area first to see if pulling into 88 will give you the best angle to back in. 12 minutes from North Pack Monadnock trail head

Quite and serene surroundings to camp and relax. Ample parking with options of washroom available. A lot of spots to do barbecue and benches to accommodate large groups. Lake nearby to swim. Park closes at around 7, so plan accordingly.

We started coming here when I was little to come tent camping. It turned into a tradition that I continued with my children. My husband and I have sense bought a travel trailer and still find ourselves always wanting to come here! The sites are private, spacious, and clean. The staff is super nice. The lake is great. Can't say enough good things about our favorite campground!! Memories from here will last a lifetime!
