Also known as: Smarts Mountain Fire Tower
Smarts Mountain rises to 3,238 feet in the town of Lyme, near the Connecticut River valley, making it the southernmost significant summit in New Hampshire along the Appalachian Trail. The wooded top is capped by a steel fire tower, erected in 1939 and restored in 2016, whose 41-foot observation deck delivers a full 360-degree panorama: the Dartmouth Skiway, Reservoir Pond, Mount Cardigan, and Mount Kearsarge spread across the horizon. A ranger cabin beside the tower, also restored in 2016, now provides shelter for AT thru-hikers.
The most popular approach is a 7.1-mile loop ascending the Appalachian Trail over Lambert Ridge and descending the Ranger Trail, with roughly 2,385 feet of gain. Lambert Ridge rewards the climb with several open quartzite ledge viewpoints before the trees close in; those pale gray and pink rocks were seafloor sediments compressed some 400 million years ago, when this edge of New England lay beside a volcanic island chain. The same quartzite spine continues south to Moose Mountain and north to Mount Cube. The Ranger Trail, blue-blazed and unmaintained, provides a more gradual descent but requires some route-finding.
The tower stairs can be icy in winter, and the Ranger Trail tends to be wet and overgrown in early spring. The fire tower earns Smarts a spot on the 52 With a View list, drawing visitors who might otherwise pass over a wooded summit.
