We’ve been going to Hammonasset for years as a large family gathering. Most sites don’t have hook ups so you have to run off battery and water storage tanks if you have a RV. My biggest gripe is lack of any enforcement. No one enforces the parks rules so some groups tend to be rowdy later in the evening, children on bikes darting in front of moving cars. Nice thing is it is fairly inexpensive and there’s several beaches to choose from.
