125,000 hikers climb Monadnock each year. The four hour round trip to the top and back on one of the shorter trails may be challenging for the average hiker. Special skills or equipment are not needed from late spring to early fall. Climbing during winter and early spring requires special equipment, clothing, and preparation. Weather on the top of the mountain is often colder and wind is often much stronger than below. Climbers should be careful climbing at any time of year, but it can be especially dangerous from late fall to early spring.
