I live full time in an RV and I can say with absolute certainty that this is my favorite RV spot so far BY A LOT.
First of all, the location is perfect. You're situated on a small, non-commercialized island that has a stunning view of the lake no matter which spot you get. The people at the park were incredibly nice, including the owners. The two guys running this park will do anything to make sure you have a good stay.
Second of all, even though this park is located in a quaint, quiet area of CT, it is still perfectly located to take a train to NYC, it's super close to Providence RI, and another quick trip to Boston. Even though this place is quiet, it is surrounded by potential activities.
I was fortunate enough to be here during fall, so everything I did was full of beautiful colors and scenery. If you are ever looking for a good central RV location, then this is it. I consider myself lucky to have stayed here.
