We crossed Lake Champlain on the ferry from Plattsburgh NY to Grand Isle. We stayed at Apple Island RV Resort. There is also a state park there. We drove across Hwy 2 to Bangor. Stop at Cabot Cheese factory and Ben & Jerry's Ice Cream factory. On the way back, don't miss Acadia National Park in Bar Harbor. We stayed at The Narrows Too RV Resort. Shuttle (free) stops at RV park. Expensive but they have different rates depending if you want to be on the wtaer. Stop at Quechee Valley KOA and visit Quechee Gorge. If you want to go more south, we like Ives Run COE campground in Tioga PA. (make reservations). We also liked Hickories City Park in Owego NY. In Bradford PA the Zippo Lighter and Case Knives factory and museum.
