I did this beautiful all day trip years ago with the Green Mountain Club. The 16 mile loop goes down the Missisquoi River (with the current), into Lake Champlain/ Missisquoi Bay, past the big blue heron rookery then back by way of Dead Creek with a mile over and back to Highgate Springs Town Park for a chance to get out of the boat. The put in is at Louis' Landing near the National Wildlife Refuge on Rt 78. There is not really any good place to get out of the boat on this trip because it goes along the Refuge shoreline. I hope tthe extra mile over and back to Highgate Springs Town Park will give everyone a break. The waters are mostly protected and shallow unless there is a north wind during the Missisquoi Bay leg.
So I would say this is a good trip for people that have good sitting in the boat endurance and want to see birds.
