Crown Jewel of NY State Park System
Worth it for the Gorge hike alone - approx 1 1/2 mile hike down the gorge complete with 19 waterfalls, some of which you pass behind. Hike itself isn't too strenuous, with the exception of the final ascent, which is called, aptly, Jacob's Ladder - 180 or so steps up to the end of the trail, it will get your heartrate going! Do wear at the very least good sneakers, your feet will get wet.
As far as the campground goes, sites are level, if somewhat rocky. I thought they were maybe a bit on the smallish side,, but maybe that was just my site (site 70). Some sites seemed tough to back into, due to lack of maneuverability. Bathrooms - showers were clean. Olympic size pool and restaurant on premises.
The campground entrance is about 1/2 mile up a hill around the corner from the park entrance. I imagine MANY campers, like I did, pull their rigs into that parking lot wondering where the heck the campground is, getting out & going into the office to ask, only to be told where to go - maybe there should be a more visible sign in that lot telling campers where to go.
