The summit of Pack Monadnock Mountain, Peterborough NH, is 1000-feet lower altitude than the Grand Monadnock Mountain to the west, but smaller isn't small. You'll feel how in-shape you are or aren't for hiking :-)
We hiked the rustically beautiful well-maintained Marion Davis trail up from NH-101 Wilton Rd to the 2290 ft peak in about 90 minutes, then returned the easier way down Miller State Park Road in about half that time.
There were rocky outcroppings and not-yet-greening (Apr 2026) grey-brown hardwood forests. Nearer the summit, there were spruce. At the top, we talked with friendly helpful rangers, (used the restrooms), and climbed the Fire Tower. We could see the taller Grand Monadnock Mountain to the west, and we could see wide open vistas, from the summit, and from halfway down Miller Rd. where the power lines cross the road.
The cost was $4 per adult, $2 for kids, and free for seniors. If there's no ranger at the Miller State Park entrance, you can pay "the Iron Ranger" (the metal drop-box :-). I think there's a small souvenir shop at the summit, but we didn't check it out. And you can drive up and park at the summit when you're not up for the hike. By the way, we guessed that "Pack" meant "small". Apparently "Monadnock" is the name the Abenacki gave it as a "stand-alone" remnant of an ancient mountain range. read more
