NOTE: A timber harvest is taking place through summer 2026 that will impact Camp Trail and Castor Pond Loop. These trails will remain open but hikers should use caution when in the area. For more information on this project, please visit our "Timber Harvest" page.
Surrounded by a patchwork of conserved properties in the Souhegan River Valley, the Heald Tract features a mixture of well managed habitats along with ample recreation opportunities. For an easy stroll, try the Heald Pond Trail, or opt for more of a challenge by taking the Camp Trail or Castor Pond Loop Trail. Visitors may spot an otter family playing in the water or a great blue heron fishing on Camp Pond at the Heald Tract, where more than seven miles of trails crisscross this varied landscape.
Trails that skirt the shores of Heald and Castor Ponds offer views of beaver lodges. The orchard and fields offer early succession habitat for fox, hares, and different species of warblers. You’ll also find great blue herons in the rookery to the north, plus belted kingfisher, Canada geese, wood ducks, beavers, deer, fox, squirrels, moose, and otter. Look for orchard blossoms and vernal pools in spring, mountain laurel blooming in early summer, a carpet of water lilies on King Brook Reservoir in late summer, and blooming eastern purple bladderwort on Camp Pond in late summer.
The original 340+ acre Heald Tract was donated to the Forest Society by Phil Heald, his brother Ross Heald, and their sister Helen Heald Rader in 1986. Since that time Phil and his family have donated a total of 1,030 acres in 12 separate conveyances to the Forest Society, with the purpose that the land be maintained as open space and used for low impact recreation and education. These lands had been in the family for more than a century and are collectively known as the Heald Tract. They had historically been well managed by the Heald family for multiple uses, including apple orchards, wildlife habitat, forest products, passive recreation, education, and flood control. Heald Pond, was formed by the state-operated Souhegan Watershed control structure. The Heald family collaborated together over a long period the create this conservation legacy— benefiting all who visit and appreciate this beautiful and diverse landscape.

The Heald Tract—A Land Stewards Perspective
by Bart Hunter
The Heald Tract was donated over a period of years by Phil Heald, his sister Helen Rader and his brother Ross Heald. Phil Heald and land steward Ray Jackson began in the 1980s to lay out trails on what was once a farm that comprised the Heald Apple Orchards, packing sheds, and a managed forest. Both Camp Trail and Fisk Hill Trail boast pure stands of beech that glow on wet autumn afternoons. Most of the trails are easy hiking with several hills. Fisk Hill Trail that runs along the Wilton-Temple town line is the steepest.
The Tract started as farm in the early 1700s by the Greely Family. Today the original Greely family homestead sits on private property in the center of the Tract. Descendents of this family still live in the area.
There are two important aspects of Heald. First is a rich, ecologically diverse habitat. It is home to nearly all mammal species found in Southern NH, including bear, deer, otter, and moose. Birds are common, as are turtles, and salamanders. A quiet hiker may find an otter family at play or a great blue heron fishing on Camp Pond. Nearby Castor Pond (named for Castor Canadensis, our native beaver) boasts a magnificent beaver dam that is 75 feet wide and 7 feet tall. It was rebuilt by the resident beavers after a flood tore it out a few years ago. Deer and ruffed grouse can be found in the abandon orchards eating fallen apples.
Human history can also be found on Heald. Two cellar holes built by the Lovejoy brothers in the late 1700s abut the McGregor Road Trail. The easternmost homestead belonged to Moses Lovejoy and features the remains of a stone platform that formed a base for the chimney, as well as a large barn foundation.
Moses’ brother Daniel’s homestead was to the west. It had a central chimney and two root cellars. A barn foundation lies just east of the house foundation. While it was about the same size as Moses’, it had less living space due to the central chimney. Of particular interest is a rectangular stone in the southeast corner of the foundation—a sill stone that supported the wooden sill that was the base for the wall. Featuring four V-shaped quarry marks, this stone shows one stage of the evolution of quarrying in colonial America. Wooden wedges would have been driven into the holes to split the rock.
These quarry marks provide us with a way to move beyond the written history of this cellar hole and to exam it from the view of an archeologist. Around 1835 quarrying technology changed with the introduction of the star drill, feathers, and wedges. The quarrymen used the star drill to drill a line of round holes in the stone. At first this was done by hand, but later compressed air drill motors were introduced to drive the star drill bits. Two L-shaped feathers are inserted in the holes so the long end of the L is down and the short end points outward at a right angle to the desired line of the split. The wedge is inserted between the feathers. Starting at one end of the line, a hammer is use to sequentially drive each wedge a fraction of an inch into the holes. This continues until the outward force of the wedges splits the stone. Therefore, when we find a stone deep in a foundation or a quarry face that has been split with showing the round hole of a star drill, we have a pretty good idea that it was quarried after 1835. In the Lovejoy foundation, all the stones have been split with the older scooped-out method that verifies that the foundation was built before 1835.
Today we have just begun to explore the potential of the Heald Tract. Its miles of trails, accessibility, rich history, and abundant wildlife make it an interesting destination for a quiet walk.
Fishing Guide
Heald Pond (King Brook Reservoir) is actually a flood control reservoir constructed in the mid-twentieth century as part of a regional effort to reduce flooding in the Souhegan River watershed including the town of Milford. This beautiful, quiet pond is nearly entirely encompassed by the Heald Tract of the Forest Society. Fishing is welcome, and expect to find warm-water species. One important caveat: No boats are allowed on Heald Pond – it’s shore fishing only. This property offers more than 1,000 acres, about five miles of trails and another pond – Castor Pond -- to explore, so be sure to bring a picnic lunch!
Yellow Blazes
This beautiful, easy walk begins at the kiosk parking area on Heald Road. (If the kiosk parking area is full, there is additional parking on the left-hand (western) side of Heald Road, approximately .4 miles past the kiosk parking. Park in front of the log barrier.) Please do not park in front of any of the gates.
Walk north along Heald Road about 1/10 of a mile until you see the yellow blazed trail entering the woods on the left. The trail winds through hemlock, red maple, and white pine forest and skirts along the northern shore of Heald Pond. There are several opportunities for excellent views of the pond – look for wood ducks, herons, frogs, and turtles in the emergent vegetation along the shoreline. In late summer, King Brook Reservoir is blanketed with a stunning carpet of blooming waterlilies. Near the eastern end of the pond, the yellow-blazed trail turns sharply to the right and continues northeast along an old woods road to the Fisk Hill-Spring Trail. Unless you are continuing up Fisk Hill (see below), turn around and retrace your path back to the parking area. This is an excellent hike for families with young children.You may want to wear waterproof shoes, however, as a few sections can be quite wet during spring.
Yellow and Orange Blazes
(Please do not park in front of any of the gates.)
From the kiosk parking area, take the yellow-blazed King Brook Reservoir Trail to the orange blazed Fisk Hill-Spring Trail. Follow the orange-blazed trail as it ascends Fisk Hill, reaching its highest point approximately 0.9 miles from the shoreline of King Brook Reservoir. If you continue past the height of land for about 0.3 miles more, you will reach an abandoned orchard from which you can glimpse views of the Lyndeborough and Uncanoonuc Mountains. From here, return to the kiosk parking area the way you came in. (If the kiosk parking area is full, there is additional parking on the left-hand (western) side of Heald Road, approximately .4 miles past the kiosk parking. Park in front of the log barrier.)
Blue and Green Blazes
(Please do not park in front of any of the gates.)
From the kiosk parking area, follow the blue blazed Camp Trail to the east of Heald Road. The lower stretch of the Camp Trail passes through numerous clusters of mountain laurel, an evergreen shrub with beautiful pink and white blossoms in early summer. The trail heads north through forest and old orchard habitats before reaching Russell Hill Road. Walk north along Russell Hill Road for about 0.3 miles to where the blue blazes re-enter the woods from the left. Shortly you will reach a small pond.
Approximately 800 feet beyond the pond, a green-blazed trail heads off to the left (west). This is the Castor Pond Loop Trail. Take this green trail for a 1.5 mile loop around an active beaver marsh. (The genus “Castor” is part of the scientific name of the American Beaver, Castor canadensis.) Look for the freshly gnawed stumps of small trees all along the Castor Pond Loop Trail. You may even spot a beaver if you are lucky. When the Castor Pond Loop Trail intersects the blue-blazed Camp Trail again, turn right (south) to return to the parking area via the Camp Trail.
(If the kiosk parking area is full, there is additional parking on the left-hand (western) side of Heald Road, approximately .4 miles past the kiosk parking. Park in front of the log barrier.)
