The White Dot Trail up to Mount Monadnock near Jaffrey New Hampshire is a difficult 4.2 mile loop hike that brings you to the summit of Monadnock with amazing views of the surrounding area above the treeline.
Take the White Dot Trail up and the White Cross Trail down. The elevation change is fairly high for southern New Hampshire at about 1700 feet, so bring plenty of water for your trip.
This is steep nearly the whole way and is one of the most hiked mountains in the northeast. Weekends are a popular day hike for families and groups, so if you want to experience Monadnock on a quiet day, try hiking up during a weekday. Day camps go up all the time, but its still a bear of a hike.
Pets/dogs: are not permitted in Monadnock State Park.
