Bike Paths and Rail Trails
Manhan Rail Trail - 4.2 miles - South Street, Easthampton to the Mount Tom Junction at route 5 in Northampton. Runs near the Arcadia Wildlife Sanctuary.
Norwottuck Trail - 9 miles - Connects Northampton, Hadley and Amherst, parallel to route 9. Uses an old railroad bridge with a great view upstream to cross the Connecticut River near the Calvin Coolidge bridge. One bad section along Damon Road, but overall it keeps you out of traffic.
UMass Conector bike path - 2 miles - links the Norwottuck Trail to the University of Massachusetts, Amherst
Keystone Arch Bridge Trail - 5 miles round trip - Huntington, recommended for hikers and mountain bikers. NOT a commuting trail.
