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?"
