Mount Kancamagus reaches 3,773 feet in the Sandwich Range, sitting east of East Osceola above the headwaters of both the Swift River and the Pemigewasset River. It is named for Kancamagus, the last sachem of the Pennacook confederation and grandson of Passaconaway, who led his people north into Quebec in 1691 after years of conflict with English settlers. The Kancamagus Highway that cuts through the region takes its name from the same figure.
Reaching the summit requires off-trail navigation; there are no maintained trails to the top. The standard approach follows the Livermore Trail for several miles before leaving the path and bushwhacking to the wooded summit, covering roughly 6 miles round-trip with about 1,800 feet of gain. Navigation skills and a compass or GPS are essential, as the dense forest offers few natural landmarks to orient by. A summit canister with a log book is typically in place, as is common for trailless peaks on the NH 100 Highest.
The summit itself is forested with no views, making this a destination primarily for peak-baggers rather than those seeking scenery. The best conditions are from late spring through fall, though the trailless terrain requires extra attention in wet or snowy conditions when deadfall and slick footing add difficulty.
