If you are traveling from Fonda on Rt. 5, toward St. Johnsville, then look for the Crystal Grove signs on the right. In St. Johnsville you will want to turn on to County Rt. 114 and head North. You will know if you are on the correct road because you will soon see another Crystal Grove sign. Stay on this road, seeing more signs, until you get to the campgrounds on the right (with a small store and parking lot). My first time traveling there from St. Johnsville seemed like it was further than on the map, I heard myself saying "are we there yet?"
