We live 25 minutes from the Spruce Run Recreation Area. When we find we want to enjoy the reservoir's atmosphere, we try to grab a waterfront site. Dry Camping only with onsite dump station and fresh water. We don't use the bathroom facilities and cannot comment about them. It's close to the historic town of Clinton, various shopping and restaurants to meet your needs.

We get the senior pass and are NJ residents, therefore the $18. We camped during the week when crowds were down. Sites aren't extremely level but I've managed to level our TT each time. Shade is plentiful if you need it. Site 7 gave enough sunlight to keep our batteries charged throughout our 4 day stay. We camped in our 27' TT in June and mid October (#15) and enjoyed the summer heat (90s) with breezes and temperatures approaching the mid 30's with wind, sun, and gorgeous moonlight over the reservoir.

We'll be here every year. Planning to bring family and grab some adjacent campsites for the experience with the grandchildren.

The sites aren't too large here, and they are a bit close together, but it's still a nice park. The beach is the best part as they have nice showers, a food stand (seasonally) and a lifeguard.
My site was gravel and not too level, but it had a good view of the lake.

This park probably has close to 100 picnic tables, so plan on picnicking here ;)
