The Manhan Rail Trail is a rails-to-trails paved recreational trail and non-motorized commuter route located in the lower Connecticut River Valley of Massachusetts in the town of Easthampton.

[1] The trail, named after the Manhan River which it parallels, utilizes the bed of the former New Haven and Northampton Railroad, which served the industrial towns of the lower Pioneer Valley from the mid-19th century until 1992.

[4][5] The Manhan Rail Trail, universally accessible, is open to walking, running, bicycling, inline skating and, in the winter, cross country skiing.

The trail also provides a non-motorized commuter transportation route linking Easthampton, Northampton, and Southampton, Massachusetts.

The Manhan Rail Trail served the surrounding community for eight years as the location for Derrill's Race.
