Thompson Pond Trail

Thompson Pond & Twin Ponds Trail System, 104-194 Spruce St, Abington, MA 02351, USA

Nearly two miles of trails through meadow and forest, on the site of the former South Weymouth Naval Air Station.


Naval Air Station South (NAS) Weymouth was commissioned on this site in March 1942, however construction work began in the late fall of 1941, a few months before the United States entered World War II. Originally the base operated blimp combat patrols. During the Battle of the Atlantic, blimps based here helped protect U.S. ships from German submarines.

The base was downgraded to a Naval Air Facility after WWII. The blimp hangars were repurposed as storage for war surplus naval aircraft. In 1949, the base was redesigned as a Naval Auxiliary Landing Field. In 1950, after the closure of NAS Squantum in Quincy, South Weymouth became the new home of the Navy and Marine Air Reserve training program. Between 1951 and 1953, three new runways were constructed, and other improvements were made to support the reserves. One blimp hangar was demolished at this time. The other remained in place until November 1966.

In December 1953 the base was recommissioned as a Naval Air Station. It remained a reserve training base throughout the Cold War era, and also hosted the Naval Air Development Unit (NADU), a secretive research & development command. NADU aircraft provided flight testing support for military research.

After the end of the Cold War in 1991, NAS South Weymouth was among many military bases nationwide that were selected for closure. The last aircraft took off from the base in September 1996, and the official closure took place on September 30, 1997.

Looking north from the trailhead, the open field before you seems vast. It’s not hard to imagine the runways that existed here in decades past.

The manmade Thompson Pond was created to help restore the natural wetlands that once existed on this site.

Trail Description

The trail was created by the Wildlands Trust. It begins by heading north through the meadow. You can follow a wide road or choose a narrower route through the grass. Red blazes lead the way. After a sharp turn west (left), the trail crosses the West Branch of French’s Stream, and continues past Thompson Pond. Through both meadow and forest, it completes a loop and eventually returns to a spot near the pond. The total trail distance is 1.9 miles. Most of the trail is flat, but there are sections near the pond with a relatively steep slope.

Habitats and Wildlife

The forest here is comprised primarily of pine, oak and maple, with plenty of greenbrier. Some species known to exist on this property are American Kestrel (a small hawk), Great Blue Heron, Wood Duck, Spotted Sandpiper, River Otter, Painted Turtle, White-tailed Deer, Coyote, and Eastern Meadowlark. At dusk, listen for the “Who cooks for you? Who cooks for you-all?” call of the Barred Owl.

ATV use is prohibited. Please be mindful of poison ivy.

The West Branch of French’s Stream flows through this property. Farther south, in the Rockland Town Forest, if flows together with the East Branch of French’s Stream. The stream continues south, and then southeast, into Hanover. On the outskirts of Forge Pond Park in Hanover, it flows into the Drinkwater River. The Drinkwater River continues to flow southeast of Forge Pond, into Factory Pond. From there, the waterway turns east and is known as the Indian Head River. It joins Herring Brook in Pembroke and Hanover to form the North River, which flows 12 miles through Hanover, Pembroke, Norwell, Marshfield, and Scituate, to the Atlantic Ocean.
