Smarts Mountain Professional Review and Guide
"A stiff start to a series of open ledges, then a steady climb to a fire tower and a 360-degree view, including the main spine of the White Mountains to the east and the Green Mountains to the west.
A popular local hike, Smarts Mountain is not a 4,000-footer, but it feels like it when you climb it. The mountain is a large, flat-topped dome when viewed from the Hanover area. Although the summit is covered with trees, it has a tall fire tower, and the approach via the Lambert Ridge Trail/Appalachian Trail (white blazes) gets you up high quickly, with numerous ledgy vistas en route to the top.
Many people like to hike both ways on the Lambert Ridge Trail, because it is on a ridge with wonderful lookouts. There are three reasons for descending via the Ranger Trail: to make a loop; because the bottom third of the trail is smooth and flat, so it is easier on your joints; and for the water. The Ranger Trail crosses a large brook about halfway down, then follows it much of the way to the trailhead."
