Where to RV on East Coast

The Pocono Mt. REgion of Pa might be interesting to you. I know one large CG, Otter Lake CG in the Stroudsburg area is literally on a huge lake with swimming, fishing, etc. available. There are other options as well. The Northwest region of NJ is also possible, with lakefront Campgrounds in the area as well. Might want to check out the Lancaster County, Pa region too. The area has numerous campgrounds, unique communities and attractions (it "Amish Country", and Hershey Park is nearby). None of those areas is very far from you at all, I don't think. You can look at https://www.campgroundreviews.com/ for info on campgrounds and descriptions so you might find something enjoyable. I would agree with others who suggest not going too far from home. Sounds like this will be a 'first time' adventure for the family and it may turn out to be too different for some! Also suggest you take notes, literally, when given instructions when renting the RV, and absolutely don't hesitate to seek help when you set up or take down the rig at the CG! Campers are generally very helpful people!

Thank you everyone. This information is helpful.

With the areas around you being among the ones that had/have the most restrictions from Coronacrud, I would think you may be better off looking to your Northwest. Bradford Pa to Alleghenny River and state park.
A lot of folks this year are thinking the same way you are with trying an rv, and New England for the ones in NY and NJ are probably high on their list of destinations, I'd try another direction, at least for this year.
From RV parky as was suggested before,,,,

I cant speak from experience on the area, but I do remember some attempts at New Hampshire and Maine trips from Mass, and you had to go quite a way up to find space even on a normal year.
Good luck.

I would suggest making use of Rvparky.com to search for parks in the Poconos or maybe around the Delaware Water Gap which are less than 2 hours from you. You can easily check them out on that site for amenities and reviews.

Never rented a rv however as a camphost have heard many tales from renters on how the pickup did not go as planned. A 9:00 am pickup turned into a 3 hour ordeal. Then how far do you think you'll get that first day? Just a few things to consider the youngins would rather be swimming than a long boring ride. Keep it close to home.
