For a scenic drive, you cannot go wrong with Route 77: its entire length is a state scenic road. The Danbury News-Times writes:
"Start at the shore and then head for the hills on this 11.5-mile scenic country road, running from Guilford Center north to the town of Durham. See turn-of-the-century farmhouses, crooked old barns and picturesque meadows. There's even a pond along the West River where you can fish, canoe or simply take in the scenery."
