All of the Appalachian Mountain Club huts and lodges scattered throughout the White Mountains of New Hampshire have some unique story to tell. There’s the Lake of the Clouds Hut, above the trees on an alpine lake beneath the summit of Mount Washington. And the 130-year-old Madison Spring Hut, with views of the Presidential Range in all directions. Now the Highland Center Lodge, at the 6,000-acre Crawford Notch State Park, built nine years ago with sustainability in mind, can be added to the list. A majority of its windows face south for passive solar heating, the frame is made from recycled local steel, and it uses eco-friendly carpets, paints, and composting toilets. Rates start at $118.
