The terrain is varied. The Boulder Loop Trail, often used for ascent, starts gradually but becomes steeper with ledges and rocky sections, including some challenging boulder climbs and a short 'tunnel' feature. The Brook Trail, typically used for descent, is generally easier with a steady decline, paralleling and crossing a brook. Be aware that the lower portion of the Brook Trail can be washed out and loose in places.
From the summit of Mount Major, which stands at 1,786 feet, you'll be treated to panoramic and spectacular views. These include expansive vistas of Lake Winnipesaukee, Alton Bay, and the southern White Mountains. On a clear day, you might even spot Mount Washington in the distance.
This trail is rated as moderate. While the Brook Trail offers an easier and more family-friendly descent, the Boulder Loop Trail involves steep, rocky sections and boulder climbs that can be challenging, especially for beginners or young children. Hikers should have a reasonable level of fitness and be prepared for varied terrain.

Beyond the stunning summit views, you'll find the remains of Mr. Phippen's Hut, a stone shelter built in the early 1900s, at the top. The Boulder Loop Trail also features a unique short 'tunnel' where a flat rock rests across two large boulders. The Brook Trail, true to its name, follows and crosses a scenic brook.
Even for a moderate hike, it's wise to pack essentials. Bring plenty of water, snacks, a map or navigation device, a first-aid kit, and appropriate footwear with good ankle support. Layers of clothing are recommended, as weather can change quickly. For winter hikes, microspikes are essential.
