Connor Mill Trail Letterbox

Sebasticook Regional Land Trust has a mission to recognize and conserve the rich wild and working landscape of Central Maine. We work with willing landowners to conserve the lands they love and the resources our community relies upon – clean water, family farms that provide local food and jobs, well-managed working forests, places to hunt, fish and recreate with our children.

The Connor Grist Mill, established circa 1815, was once used to grind grain into flour and meal, supplying the small town of Unity and the surrounding area. It was abandoned around 1936. All that remains is an old millstone and rocks from its foundation scattered along the banks of Sandy Stream. As you walk the trail named after this important mill in Unity’s history, enjoy views of the stream that once provided the power to this and many other mills like it.
If you’re visiting in the spring time, keep an eye out for the Trout Lilies that are particularly abundant here. These yellow flowers are named after the mottled look their leaves share with brook trout markings.


• Start at the Connor Mill trail head on Route 202/9 near its intersection with Quaker Hill Road.
• Follow the blue blazed trail markers.
• You will cross a wooden bridge over a small runoff stream that flows into Sandy Stream on your right.
• When the trail splits, head left.
• You will see an old millstone in the ground to your right. Take a look and then get back on the trail and keep going, almost there!
• Keep following the trail straight through a stand of tall trees, over another wooden bridge, and up a small incline.
• As you continue to follow the trail, you’ll come across a big tree with 5 trunks to your right.
• Walk slightly past the tree and look to your right, around the back of the tree.
• Under the pile of rocks at its base, you’ll find the letterbox.
• After stamping in and replacing the box as you found it, continue following the blue blazed trail.
• Sandy Stream will be on your left and eventually you’ll loop back, with the millstone on your right as you make your way back to the trail head.
