Alaska has been leading the way when it comes to environmentalism, and with more than 100 national and state parks, plus dozens of threatened or endangered species in the state, this comes as no surprise. Ecolodges, which run solely on alternative power sources, have emerged throughout, and many ecotourism operators offer ecotours and adventures to explore the vast tundra, colossal glaciers, soaring mountains and pristine wilderness of the majestic landscape. Big, remote and wild!

Hawaii has been practicing sustainability for millennia. For residents and Natives who hold fast to the notion of malama ‘aina (to care for the land), staying green comes easy. A long-time member of the International Ecotourism Society, Hawaii offers more than just ecofriendly beach activities, such as surfing, kayaking and scuba diving. You can also learn about ancient sustainability methods at Pu‘uhonua o Hōnaunau National Historical Park or learn about Hawaiian culture at a hula festival.

California, which already has hundreds of thousands of green jobs, has shifted the ecotourism landscape. For example, about 95 percent of Yosemite National Park is protected from urban activity, while efforts to decrease emissions for the other 5 percent include hybrid shuttle buses and green concessions. Meanwhile, in Palm Springs, you can go on eco-friendly excursions to the San Andreas Fault, Indian Canyons and Joshua Tree National Park.

The Pacific Northwest has always been a pioneer in the green movement. Surrounded by miles of natural beauty, there is plenty to explore by foot, and with efforts to support its growing cycling population, Oregon has made way for tons of trails and bike routes – so there’s no need to start that engine. Amity Vineyards, a sustainable vineyard since 1991, produces three “eco-wines” that are both organic and sulphite-free.

While it’s home to wildly diverse terrain, including Glacier and Yellowstone national parks, Montana has been targeted for natural gas drilling in recent years. However, in places such as Missoula, Whitefish and Bozeman, efforts have been made to bring the region back on the eco-track. Hotel Terra Jackson Hole, the first LEED-certified hotel in the state, uses water conservation systems, alternative energy and 100 percent organic towels, mats and bathrobes.

Traveling in Colorado as an ecotourist is hardly a challenge. Residents are understandably keen to preserve the state’s natural beauty. Many Colorado attractions and lodgings are dedicated to the LEED Certification Program, with the Museum of Contemporary Art Denver being the first gold-certified museum in the nation. Local tourism companies offer eco-friendly adventure activities – whether that means rafting through river canyons or exploring Rocky Mountain National Park.

At Mount Rainier National Park, ecotourism is king. Stay at Adrift Hotel, a certified Social Purpose Corporation on the Washington Coast, for an eco-first approach to boutique hospitality. Hiking, rock climbing and kayaking are popular eco-activities, while a visit to Seattle offers visitors the chance to sample sustainably sourced produce, such as seafood, coffee and beer.
