Burnt Mills Grist Mill Ruins
Located within the Burnt Mills Floodplain Preserve, these stone foundations are the remains of a post-Civil War grist mill. Purchased by the Schley family in 1928, the mill was dismantled, leaving behind its historic stone ruins along the Lamington River. Today, the site is surrounded by a scenic 11-acre riparian sanctuary famous for its vibrant spring displays of Virginia bluebells.
The story
You wouldn't know a post-Civil War grist mill once anchored this stretch of the Lamington River if you didn't know where to look in the trees. The mill ran its coarse grain operations here until 1928, when the wealthy Schley family purchased the parcel and dismantled the timber and frame structure. They stripped the building bare, leaving behind only the heavy stone foundation walls rooted directly into the riverbank floodplain.
Rather than developing the plot, nature took the wheel. Today, the 11-acre site sits inside the Burnt Mills Floodplain Preserve, overseen by the Raritan Headwaters Association. The stone masonry has softened under decades of moss and leaf mold, tucked quietly into a riparian sanctuary best known for bursting into carpets of native Virginia bluebells every spring.
What it's like
Park your car at the small crushed-stone pull-off right near the Burnt Mills Road bridge. From there, trail access is immediate and straightforward. The ground along the Lamington River gets damp and muddy quickly after rain, so ditch the clean sneakers. Walk the short loop through the trees to trace the outline of the stone mill foundations—it’s low-trafficked, unpretentious, and completely open to the public without fees.
The move: Park at the crushed stone pull-off near the Burnt Mills Road bridge and take a romantic walk through the floodplain preserve to photograph the historic stone mill ruins and enjoy the river views.
