This 1.5-mile rail trail connects the Cohasset MBTA station with Whitney and Thayer Woods, Turkey Hill, and the 3500-acre Wompatuck State Park. Composed of graded crushed stone, it is suitable for bicycles and wheelchairs. Stroller-friendly.
The Whitney Spur, a railroad spur, once connected the Hingham Naval Ammunition Depot (now Wompatuck State Park) to the Old Colony Railroad’s Greenbush Line. In 2003, the DCR sold the land for the Cohasset commuter rail station and parking lot to the MBTA, in exchange for the construction of a rail trail on the former rail spur. The 1.5-mile Whitney Spur Rail Trail now connects the Cohasset MBTA station to Wompatuck State Park.
The 3,500-acre Massachusetts state park served as the Hingham Naval Ammunition Annex from 1941 to 1965. It stretches into four towns – Hingham, Cohasset, Scituate and Norwell, and features numerous seasonal campsites, plus fishing and non-motorized boating on the Aaron River Reservoir. There are 12 miles of paved bike paths, plus 40+ miles off-road trails for hiking, mountain biking, horseback riding and cross-country skiing. Stroller-friendly in some sections.
The land at Wompatuck State Park was commonly used by the Massachusett tribe, led by Chief Josiah Wompatuck. English settlers purchased the land from Wompatuck in 1655. In the 1700s, early settlers and ship captains held title to the area, but the land was never extensively developed. During the 1800s, families maintained woodlots and grazing lands here, and the streams powered the Stockbridge Shingle Mill. Water from Mt. Blue Spring was commercially bottled.
In 1941, the United States government established the Hingham Naval Ammunition Depot Annex (known by locals as the “Cohasset Annex”) on the site. Land was acquired from private homeowners for the purpose of expanding the Hingham Naval Ammunition Depot nearby (now Bare Cove Park). It remained in use until 1965, and served both World War II and the Korean Conflict.
Scattered throughout the property are over 100 decommissioned military bunkers, which were used to store ammunition. Explosives such as TNT-loaded depth charges, bombs, fuses, projectiles, and cartridges were produced and stored here. Many of these bunkers have been backfilled, but some remain exposed. There are several old military buildings on the property, as well as an abandoned railroad. Most buildings have had their roofs and windows removed and are open to the elements.
The U.S. Navy deactivated the Cohasset Annex in 1963 and declared the land as “surplus.” The Commonwealth of Massachusetts took possession of the land in 1966, and began developing it as a public park the following year. The park itself opened in 1969. Since then, 725 acres have been added.
The Mount Blue Spring is currently closed. Typically, the Mt. Blue Spring is open seasonally, featuring water drawn directly from a natural aquifer. You can find it in a shed with an adjacent parking area, on Union Street in the park, between markers E14 and E1, not far from the Transfer Station area. The water is tested frequently for safety.
This particular trail is about 1.5 miles in length. It begins at the MBTA Commuter Rail station in Cohasset, and is paved up until the point where it meets Route 3A. On the other side of 3A, all the way to Wompatuck proper, it is composed graded crushed stone. The trail is wide, and relatively flat, with a slow but undemanding uphill climb. It connects in several places with trail networks in the park as well as in Whitney and Thayer Woods and Turkey Hill.
Wompatuck State Park offers numerous woodland trails for hiking, dog-walking, horseback riding, cycling, and cross-country skiing. For mountain bikers, the park is home to one of the longest section of switchbacked singletrack in the state. The Wompatuck Trail is ADA accessible.
