While it is not handicap accessible, Mt Major is a fairly easy hike for a person in reasonable condition. It is a very popular hike and can be crowded on weekends and holidays. I prefer a mid-week hike to avoid the crowd.
For those coming to New Hampshire for Liberty Forum, you won’t need much equipment to hike Mt. Major. Hiking always requires proper judgement and preparation. If conditions are reasonable minimal equipment will get you to the top. The trails are well worn and snow is packed down by the stream of hikers.
