The MSG is blazed with white rectangles. It is regularly maintained, and is considered moderately difficult hiking. Mount Monadnock is regarded as a challenging hike for novice hikers during favorable weather conditions. As the crow flies, the MSGT route is never more than a mile or two from a public road, however, cliffs and steep terrain make access much more difficult in some areas. Trail descriptions are available from a number of commercial and non-commercial sources, and a complete guidebook with topographic maps is published by the Monadnock-Sunapee Greenway Trail Club.
