This  RV park on the outskirts of Ticonderoga offers full hookups and can also accommodate tents. Seasonal sites are largely separate from short-term campers and they are clean and well-kept. Short term sites, however, are near the road;  a few of them (S1-S4) are behind the office, closer to the dumpsters and workshop and I'd probably avoid those. Sites are generally level and close together. I was there mid-week and most of the short-term sites were empty. There was limited wi-fi. 

With COVID-19 restrictions this year, the bathrooms are closed to those who have facilities in their RV. There's also a drought and they're on a well, so water conservation is essential. Coin-operated shower.

There aren't a lot of amenities onsite; there's a a small playground and basketball court, but summer of 20 those were closed. Rogers Rock State Park is nearby, however, with boat access and a beach. Ft Ticonderoga is a few miles to the north where you can explore history with re-enactors.
