If you google for things to do along I-91 in Vermont, one of the top things on the list will inevitably be Quechee Gorge Trail. The state park made for a convenient and affordable stop for the night, with direct access to the trail and easy access to the shops nearby. Heads up though, the trail from the campground down is pretty serious so if you aren’t a big hiker take the shortcut out to the road and join the trail at the bridge where things are much easier.
