Mount Cabot- Unknown Pond Loop Professional Review and Guide
"A long climb through prime moose habitat to the top of the northernmost 4,000-footer in the White Mountains, across two other peaks, then down to a mountain pond. The hike up Mount Cabot, the northernmost 4,000-footer, and the hike into Unknown Pond, a scenic tarn, are both excellent out-and-back routes. When hiked as a loop, the route includes two more peaks, the Bulge and the Horn, along the Kilkenny Ridge.
The Bulge (elevation 3,920 feet) is a wooded, nondescript hump, but the Horn (elevation 3,905 feet) is a rocky point with excellent views to the south and west. Only fast, experienced hikers should attempt this loop as a day hike, as it is a long 11.6-mile loop. Consider this for an overnight trip, spending the night at Cabot Cabin near the summit of Mount Cabot."
