The bare summit of Mount Monadnock offers 100-mile views southeast all the way to Boston and northeast to the White Mountains of New Hampshire. One of the most-climbed mountains in the world, Monadnock is unlikely to be sparsely populated when you visit, but that won’t hinder your fun.

Older kids, more so than younger ones, will likely enjoy the challenge of the climb. Many young children often climb the mountain (or attempt to), but only you know what your child can handle at any given age. All hikers on Monadnock should wear proper hiking shoes and carry at least 2 quarts of water.

Forty miles of hiking trails crisscross the park, heading toward the summit from all sides. Speak to the rangers when you arrive; they can offer suggestions and tips. Dublin Trail and White Dot Trail are two of the most popular routes. For a different route, try White Arrow Trail, which offers a rocky scramble in its 4.6-mile round-trip to the summit. From the parking lot, take Old Halfway House Trail, a well-packed trail that is fairly level until it joins Old Toll Road just before the Halfway House site—a hotel once stood in what is now a meadow. White Arrow Trail starts across the meadow. Follow its rocky, wide path 1.1 miles to the summit—kids will enjoy the adventurous trek over the rocks and will be rewarded with views and a nice rest atop the summit. After enjoying the view and the company, head back the way you came.

Remember: The summit of Mount Monadnock is above treeline, and the weather can be harsh. Plan accordingly; even if the weather seems mild at home, it can change drastically at the summit.

Turn your day trip into an overnight at the park’s Gilson Pond Campground. Call 877-nhparks (877-647-2757) to make reservations.
