Welcome to the RoadTrip America Forum!
I think you'll find the Lake Champlain area to have plenty of things to do to fill your time with. Heading out of Burlington on I-89 or US-2 will lead you to many great places for photography. Camels Hump is just one place that comes to mind. But you are also near to Mount Mansfield, which is the highest peak in the state. Anywhere in the Green Mountains I'm sure you will find what you are looking for.
Church Street is one of the most popular destinations in the city, with shopping, cafes, etc.
Are you heading to the flagship King Arthur store in Norwich?
