Mount (Grand) Monadnock Trail Professional Guide

Detailed Trail Description from our Guidebook

"Mount Monadnock is to central New England what Mount Washington is to northern New England, and it has the dubious honor of being one of the most visited peaks in the Northeast.

Tens of thousands of hikers are drawn to the Grand Monadnock each year for many of the same reasons that Henry David Thoreau and Ralph Waldo Emerson were attracted in the nineteenth century: The sculpted mountain, capped with a barren summit, is the unchallenged ruler of the low, surrounding hills that stretch west to Vermont and east to the Atlantic."

Great trail, even for little kids - my son -age 2 was carried most of the way, but his big sister, 4, hiked this all on her own.:-)

The Marlboro trail was a great hike. There are no signs to the small parking lot - you just have to have faith as you drive down an increasingly rutted dirt road that you will find it. The trail itself is well marked, but it rises continuously and at times steeply to the summit. Fabulous views from many locations, and of course a 360 panorama from the summit. We came down the White Arrow trail, then turned right onto Ampitheater and climbed over Monte Rosa, looping via the Marian Trail back to Marlboro. This is more challenging, especially because the entry to Ampitheater is not marked (it is on the right hand side of White Arrow, opposite a sign on a trail to the left marked "To Side Path"). The footpaths surrounding Monte Rosa had hardly any hikers even though it was a crowded weekend. You have to be alert for the trail markers and cairns in this area.

Great hike. Marlboro trail was moderate to difficult with 2 very steep spots but the rest of the trail was nice constant elevation gain. The summit of Monadnock is probobly the best summit in southern New England. No roads or chair lifts to the top so everybody hiked up. Though it does get crowded on the "white" trails, the other summit trails like the Dublin, Marlboro, and Pompley are great trails. Awesome views entire way up and at the summit

I decided to go on a hike on Mt. Monadnock and looked at the trails I could choose from and arbitrarily chose the Marlboro hindsight I probably should have researched a bit more because I think this was one of the harder trails to start off with since I'm new to hiking. Right off I have to say the trail guide was very accurate except for one detail. When I turned into the road to the trail head I almost turned around because it was literally two ruts with trees growing up on both sides almost touching the sides of the if you are expecting a well marked paved road with signage it's not there. I think the only reason I kept going was there really was no place to turn around...I would have had to back up and I just kept's got to be up here. There is a small parking area and one sign marking the trailhead...again for first timers...if you are expecting signs and arrows pointing the way you are out of luck...the trail was pretty clear though and look for cairns telling you that you are on the right direction. If you are out of shape the final leg of the trail can be quite tricky. Bring a big bottle of water...bug spray....and a snack. I felt the effects of the hike in my legs for about a week after. All in all a good trip though.
