Mt. Monadnock offers a quiet and beautiful hike. There are several trails through the woods, all an easy to moderate level. There are many rocky areas on the trails, so make sure you wear good shoes (especially after a rainstorm). I've read that this is a popular area for hikers, so I was expecting to run into a lot of people on the gorgeous summer day, but maybe because it was a Wednesday, I only saw about 10 people on the trails. There's a $3 entrance fee.
