Book a 4-hour kayak river trip for 2 people with Umiak Outfitters.  Choose either the Lamoille or the Winooski River.  http://www.umiak.com/default.htm

Lamoille River:  One of the most scenic stretches of river in the Northeast! Covered bridges and old farms make this river a true Vermont treasure.  This is a gentle, slow-moving river and is perfect for beginner paddlers.  As you float slowly through the lush New England landscape you will be awed by views of the Green Mountains towering above you.

Winooski River:
The Winooski River is a favorite of wildlife lovers.  As it winds its way through the densely wooded landscape, you may see otters, deer, or even an occasional moose as they come out of the woods to drink from the river.  The Winooski is a bird watcher's paradise.  The Great Blue Herons and Kingfishers call this river home because of its incredible fishing.  Anglers enjoy this fact as well.  The 4-mile trip takes roughly 2 hours to paddle.  You'll see magnificent views of Hunger Mountain and the Worcester Mountain range, as well.  It is a very gentle section of river suitable for first-time paddlers.
