Lake Neshonoc is great!
Great place to go kayak, decent place to fish, and good access to bike trail. The lake is about 600 acres in size and about 11 feet deep at the deepest point. Lake Sturgeon, Bass, Muskie, Pike, Walleye, and Bluegill can be caught at this location.
The campground is more for motorhomes/rvs and the "glamper" types. Not ideal for tent campers. You can also rent cabins of all sorts of sizes.
