We camped there in a 29’ Rv trailer. My biggest issue was finding a site where I could put out my portable solar panel as we were going to be there for 7 nights. Only going off the reservation site picture it looked like at least some sun. But it was very shady and sort of up hill site. Yes, it just means a RV no bigger than 35’. There are about three streets there that offer sites that size. I dont think they pay much attention to RV length, as there was a 40’ motorhome next to us. Most of Blackwoods is geared towards camper van and tents. It is a nice park. A 5 minute walk to the ocean and beautiful sunrises. Utilize the free bus / shuttle system as parking can be an issue. Also check out Schoodic Woods National Park Campground. We did a week at each.

I don’t believe so, we camped there last September in our 27” trailer. But be aware that you don’t have much room on the pull through sites. Just enough for our truck and trailer.
