Just off of highway 19, across from the Mabou Marina is a little gravel pit below the bridge along the water. To be clear, the actual marina parking lot has signs prohibiting overnight parking so this is the spot across the road. Big enough for a couple vans or a small camper and is conveniently right in town if you need gas or groceries or anything of the like. Some road noise but the road is by no means a busy street. There are trash cans across the street at the marina but no facilities otherwise. Good place to rest after a long day exploring the Cabot Trail.
