Trails through woods and wetlands bordering Pine Brook and Upper Chandler Pond.


The lands within, and surrounding, the Thaddeus Chandler Sanctuary were once developed as cranberry bogs. There are a number of manmade irrigation channels still present, but the bog areas have become considerably wooded. Wetlands are present as well. This is a large, well-maintained property with about 3 miles of trails.

Trail Description

From the roadside parking area, three trails are immediately visible.
• The wide, road-like, white-blazed trail leads to Upper Chandler Pond.
• The mid-width, blue-blazed trail provides a circuit around a large portion of the property.
• The narrower, wooded yellow-blazed trail extends to the southeastern boundary of the property, and includes several footbridges over wetlands, canals, and Pine Brook.

In addition, the red-blazed trail crosses through the middle of the property. An unmarked spur trail leads off the yellow trail to Osborn’s store. Another unmarked spur trail leads to a water tower. All of the trails (totaling about 3 miles) are well maintained, and most are smooth and free from prominent root growth. A portion of the Bay Circuit Trail passes through this property as well.

Habitats and Wildlife

The woods within the Thaddeus Chandler Sanctuary are primarily pine, with some oak, birch, beech, sweet pepper bush and greenbrier. There is a lot of moss to see in the wetter areas that border the northern portion of the yellow trail. There are vernal pools as well, and freshwater wetlands. Upper Chandler Pond forms the sanctuary’s western boundary.

Pine Brook finds its source in Upper Chandler Pond and flows through Duxbury to Lower Chandler Pond. It continues into Kingston, flowing through Reed’s Mill Pond and eventually into the Jones River.

Fish commonly found in the 10-acre Upper Chandler Pond include chain pickerel and largemouth bass.
