The Tripyramid massif includes three peaks: North Tripyramid (4,180'), Middle Tripyramid (4,140'), and South Tripyramid (4,100'). The latter peak is not considered an official 4,000 footer because there is not a sufficient change in altitude between its neighboring peak.
The Tripyramids are best known for their slides, exposed slabs of rock that are visible from long distances, offer great views while hiking, and make for a unique trail. It is the norm to climb all three peaks in a day.
Strenuous: The Tripyramids altitude and location belie the strenuous nature of an 11-mile loop that tags the summit of all three Tripyramids. The loop begins with the gentle and wide Livermore Trail. At 2.6 miles there is an intersection for the south end of Mount Tripyramid Trail. Most hikers continue on Livermore Trail for one additional mile to the north end of the Mount Tripyramid Trail. There, the real hiking begins, ascending a steep, rocky, and mostly exposed 1.2 miles to the summit of Mt. North Tripyramid. From this summit, the final 3.7 miles of the Mount Tripyramid trail tags the remaining two summits, descends another rocky slide below the south summit, and finally links back to the Livermore Trail at the southern end.
Winter hiking anywhere in the White Mountains requires specialized equipment and skills, and experience in coping with weather, navigation, and winter gear. Extremely severe storms can develop suddenly and unexpectedly, especially above treeline. The combination of high wind and low temperatures has such a cooling effect that the worst conditions on the Tripyramids are approximately equal to the worst reported from Antarctica, despite the much greater cold in the latter region. Hikers interested in extending their activities into winter are strongly advised to seek out organized trips with leaders who have extensive winter experience. Several AMC chapters offer winter hiking and backpacking instruction, and AMC offers several guided winter mountaineering trips; search for "Instruction" in AMC's activity listings. Helpful information can also be found in the AMC Guide to Winter Hiking and Camping .
