Near the interior of California’s mid-region, among the Giant Sequoia trees—some of the largest on Earth—that made it famous, is tucked Sequoia National Park. Established as the second national park in the U.S. in 1890, the mentality here is “big,” and in addition to larger-than-average trees, it’s also home to the highest peak in the lower 48 states: Mount Whitney.

Being such a “big” place has proven a natural lure to adventurers nationwide. That’s why, only a few years ago, architect Burr Hughes chose the space to develop a backcountry, bungalow retreat. Today, the ecologically responsible operation is known as Sequoia High Sierra Camp.

Hughes’ master’s degree in architecture featured an emphasis in sustainable design, which was put to work as he set out to construct 36 canvas bungalows on 40 acres 8,282 feet above sea level. Twenty of those acres are set aside as wetlands, and the others use “xeriscaping,” an irrigation-free landscaping technique.

Natural materials, including sustainable lumber, were incorporated into the building and décor of the camp, as well as low-flow showers and toilets, and a kitchen powered by a low-emission generator that’s fueled by biodiesel. All of this adds up: Typical guests to the camp use fewer than 16 gallons of water per day, compared to 50 gallons at an average hotel. But don’t let it fool you—Sequoia High Sierra Camp is a fine-lodging stay, even if it is camping.
