Check out: http://belknaprangetrails.org/belknap-range-trail-map/ for all details. So much work has been done on all the trails. They are most all in great condition and so much fun to hike. Yes, it says accessible till October, but you can walk up the auto road and hike Belknap all year, or access them via Piper or Gunstock. Snowshoe or with crampons. Fun.
I usually hike the little trails at Major as I'm not a fan of the mountain stampedes....hence my rating is not 5. This trail has great views, some challenges on the southern part and is easy to follow. I'm a huge fan of all the trails at Major and encourage anyone to try some of the little ones you see heading out from the bottom of the Brook trail. (Bee Line...A Line etc.) Look for the Man of Major: Art!
My family and I climbed Mt Major today. We had a all different ages from 7 to 65. We went up and down the Orange trail (Boulder Loop). It had about 3 sections that were a bit tricky going up and down. However, we had a blast! The view from the summit was beautiful. The markers were easy to spot when we were climbing up. But, it was getting pretty dark (and eventually it was dark!) as we were descending and it got harder to spot the orange markers. It took us an hour and a half to get up and an hour and a half to get down.
