Trail Description

Nashua River Rail Trail

The Nashua River Rail Trail is a 12.5-mile (20.1 km) paved mixed-use rail trail in northern Massachusetts and southern New Hampshire under control of the Massachusetts Department of Conservation and Recreation (DCR).

It roughly follows the course of the Nashua River, passing through the towns of Ayer, Groton, Pepperell, and Dunstable, Massachusetts and ends about a mile across the New Hampshire state border in Nashua, New Hampshire. The trail is frequently used by walkers, bicyclists, inline skaters, and, in the winter, cross-country skiers.


Ayer was a major junction for both north-south and east-west rail lines during the rapid development of railroad transportation. The Nashua River Rail Trail sits on the former Hollis branch of the Boston and Maine Railroad. The line was originally part of the Worcester & Nashua Railroad that connected Worcester, Massachusetts and Nashua, New Hampshire, which was opened on July 3, 1848. The line was extended to Portland, Maine in 1874 and the Boston & Maine Railroad took over the line in 1886 and called it the Worcester, Nashua & Portland (WN&P) Division. Between 1911 and 1912, a second track was added from Worcester to Nashua. With the gradual decline of rail transportation, the line fell into disuse. Passenger service on the line ended in 1934, and the last freight train ran on the line in 1982. Some concrete signal bases can still be seen, and railroad plates and ties can be found buried under the sand.

The DCR bought the Hollis Branch in 1987, and the trail was paved by Mass Highway between 2001 and 2002. The official opening and dedication was on October 25, 2002.


The Nashua River Rail Trail travels along a flat, scenic landscape with many opportunities to see wildlife. The trail passes through wetlands, ponds and swamps where a variety of animals such as beavers and herons can be seen, woodlands, and, toward the end of the trail, a few farms (cows can be seen on occasion).

At the Ayer trailhead, which is close to the Ayer commuter rail station offering access to rail service between Boston and Fitchburg, there is a 60-space parking lot with non-flush public toilets. There are several other parking lots along the trail, which crosses many roads and bridges. Trail users can stop for refreshments in nearby Groton Center or at a restaurant and ice-cream stand in Pepperell. At the Nashua trailhead, free parking is available at Yudicky park.
