Camden Hills State park is centrally located, just at the edge of downtown Camden. It provides a great home base for hiking, biking, kayaking and exploring the Camden/Rockland area.
The park has both rv and tent sites, and a nice mixture of wooded vs open sites. Many of the non wooded sites have no shade, and it was in the 90s the weekend we were there in June. However, the grassy sites are very accessible and in the front of the park, which we liked. The park sits on both sides of Rt. 1, and the bottom side is on the water. It has a number of picnic spots and a few nice walking trails that go to the water. The top portion of the park, where all the rv and campsites are, has direct access to Mount Megunticook, and offers easy to advanced hikes.
Our site had electric and water hookups. Many in the park do not. There is a dump station. The park rangers were very friendly. There is a charge for Wi-Fi, and cell service is good enough.
There are many quality restaurants in the Camden, Rockland, Rockport area, as well as good bakeries and coffee shops. The Camden Farmers market is right downtown. You are less than 10 minutes from central Camden, and 20 minutes to Rockland.
