2 of the nicest one I like are
1. North Pole Campground
2. Lake George RV Park
Both are excellent
In the Hudson Valley we loved Interlake
It’s near Rhinebeck
Sampson State Park is wonderful
It has a 40 ft limit.
I don’t know why, the sites are huge
Stay away from Corning/ Watkins Glen KOA and Bath KOA
Same owners, way over priced. I’d rather boondock or
If you can get a site
Ives Run Army Corp campground at Lake Hammond in Tioga PA is only $40/night full hookups. The fullhookup loops are amazing. $20 for seniors with the national park pass.
It’s about 1/2 from Corning and about 1 hour to Watkins Glen.
Here is a video of Ives Run
