I lived in that area of NY state most of my life. My family also had a place on Keuka Lake when I was in my teens and, in my opinion, the Finger Lakes region of NY state is a beautiful, picturesque region. Here's a link to what I posted last year relating to campgrounds in the Watkins Glen area (#11 post):
Campground near Watkins Glen, NY
If, by chance, you're going to be in the Watkins Glen area for the July 4th weekend and if you like auto racing I suggest you check out the SCCA Nationals at Watkins Glen International. They're the best and most entertaining races of the year (I've been attending races there since 1962 and yes, the Nationals are better than NASCAR) and very reasonable money wise. It's also an event with not many campers and makes for a nice, low keyed, relaxing weekend.
Most all camping there consist of boondocking...no electricity or water, although there there are many water spigots available throughout the campgrounds along with clean bathrooms and showers at no cost and three dump stations.
Weekend advance admission is $25.00 per person and $30.00 at the gate. Camping: advance pricing available $50.00 until June 15, 2014. After June 15, tickets can be purchased upon arrival at Gate 2 for $60.00. The price for camping is good for three nights, from Friday 7:00 am, July 4th, till around 10:00 am Monday, July 7. Not a bad deal not to mention good racing all weekend long. Also, the paddock and garage is open to all. The only places you can't go is in the pits and across the spectator fences to the track itself. And the grandstands are free.
Before you ask, no, I don't work for Watkins Glen International, but the SCCA Nationals weekend is a nice, reasonably priced weekend to camp and it's a real good time. Been there, done that for the past 40 some years and it's still fun.
