Mount Weeks stands at 3,901 feet as the high point of the Pliny Range, a quiet stretch of the Kilkenny Ridge within the White Mountain National Forest north of Berlin. The summit is completely forested with no open views, its character defined by a soft needle-duff floor, dense ferns, abundant fungi, and the deep stillness typical of this lightly visited corner of the mountains. Along with neighboring Middle Weeks and South Weeks, the peak honors Senator John W. Weeks of Massachusetts, whose 1911 Weeks Act authorized federal purchase of the Eastern timberlands that became the White Mountain National Forest.
The standard route begins at the York Pond Trailhead inside the Berlin Fish Hatchery, roughly 7.4 miles from NH Route 110. The York Pond Trail climbs through forest with a few easy stream crossings and a small dam before reaching the Kilkenny Ridge Trail junction at 2.4 miles (2,700 ft). From there the ridge continues 1.3 miles to the summit, for a round-trip of about 7.4 miles with roughly 2,230 feet of gain. Traffic is very light, and the Kilkenny Ridge section can be overgrown with blowdowns and sparse blazes; carrying a downloaded GPS track is a worthwhile precaution.
One practical consideration: the fish hatchery gate is posted 8 a.m. to 4 p.m., so timing the return accordingly matters on longer outings that also include Middle or South Weeks. Fall is a particularly rewarding season, when foliage brightens the forest and York Pond mirrors the hillsides on the walk in.
