What campers like
Waterfront viewing spots: Kring Point State Park Campground offers sites with dual water views. "I am tent camping and found my site (105) to have a couple of relatively level areas to choose to set up my tent on. This site is on Goose Bay, but the sites across the road are on the St Lawrence River just a few hundred feet away."
Dark skies for stargazing: Some campgrounds offer minimal light pollution, allowing for stellar night views. One camper at Swan Bay Resort mentioned: "Quite dark at night, but that was a bonus as we were able to see the Milky Way!"
International shipping observation: Many riverfront sites provide views of cargo ships traveling the seaway. "Watch the cargo ships cruise the channel," notes a camper who found this passive activity fascinating during their stay at Wellesley Island.
What you should know
Boat-only access: Several campgrounds including Mary Island State Park Campground require watercraft to reach them. "You can only get to it by boat. How awesome!? Every site is far away from the next and each has its own unique and beautiful view of the water and surrounding islands."
Seasonal operation: Most campgrounds close between late September and mid-October, with most opening in May. Operating seasons vary slightly between parks.
Wind conditions: Strong winds can damage equipment, particularly awnings. One camper noted: "Our neighbor who has camped here seasonally for the last four years mentioned that he lost three awnings to the wind."

Tips from RVers
Concrete pads: Swan Bay Resort provides level concrete pads suitable for larger rigs. "All of their sites are on slabs, neat and clean hook ups. There is river views from just about every site which is nice and then there are sites right on the river."

Electric availability: When booking, verify whether electric sites are available as options vary. "When we got there there was no one in the sign in station. No electricity or water hookups. We reserved online and there was a mix up."
