Backpacking -- The White Mountains of northern New Hampshire offer some of the most challenging and scenic backpacking in the Northeast. The best trails are within the 773,000-acre White Mountain National Forest, encompassing several 5,000-plus-foot peaks and over 100,000 acres of designated wilderness. Trails range from easy lowland walks along bubbling streams to demanding ridgeline paths buffeted by fierce winds. The Appalachian Mountain Club (tel. 603/466-2727) is an excellent source of general information about the New Hampshire outdoors; their huts offer basic shelter and a certain spartan comfort in eight dramatically situated cabins. Reservations are essential.

In addition, a number of three-sided Adirondack-style shelters are located throughout the backcountry on a first-come, first-served basis. Some are free; others have a small fee. Pitching a tent in the backcountry is free, subject to certain restrictions, and no permits are required. Check with the White Mountain National Forest headquarters (tel. 603/528-8721) or a district ranger station for rules and regulations. The Appalachian Trail passes through New Hampshire, entering the state at Hanover, running along the highest peaks of the White Mountains, and exiting into Maine along the Mahoosuc Range northeast of Gorham. The trail is well maintained, though it tends to attract teeming crowds along the highest elevations in summer.

Everything, including sleeping bags and pads, tents, and backpacks, is available for rent at Eastern Mountain Sports (tel. 603/356-5433) in North Conway, at reasonable rates.
