If in the fall, double check campgrounds as some may close early. Seafood is fantastic. Since you are in the neighborhood, PEI is nice cycling and then the Iles Madelines are a 5 hour ferry ride away from Souris. A really different place. If you go, the loupe marin (seal) is excellent.
coming from the US you will enjoy the two exchange rates: CD$ are about $0.70 US, and the distances are in kilometers, 1.6 to the mile so it s not 10 miles to camp, but only 6!
P.S. Where in VT, I'm in Bradford.
