Black Rock State Park is a beautiful campground located on Route 6 in Thomaston. The bathrooms are large with showers, and while they are clean the doors do not seem to close (at least in the ladies room). It didn't hurt the experience at all; at least I am not using leaves and a rock. The sites are spacious and very clean, and the setting is peaceful and breathtaking. You can hike up the mountain or walk to the beach... there is also a field for playing and an office for your ice and firewood needs. Check-in/Out is 1 p.m. and it is $16 for the first night and $13 for each additional night. They are open as of April 15, and daily from Memorial Day-October 2. The staff is friendly and helpful, they even deliver your firewood to your camp for you if you need them to. No electric/water on the individual sites but there is sewer and dumpsters, as well as water and bathrooms located throughout the campground.
