I'll just chime in to say that if your ACA tour doen't include the Island Line trail north from Burlington and across the lake, you might want to do it on your own. It's an old rail bed built across the lake from Colchester to South Hero, and it's quite the experience to cross Lake Champlain by bike. There is a gap in the bikeway, which is crossed by ferry in August. But even without the ferry, I'd ride the 3 miles into the lake as far as the cut just because the views are fantastic.
