Jackson has two National Parks at it’s doorstep. This offers Jackson residents one of only two remaining intact ecosystems in the lower 48 states, The Greater Yellowstone Ecosystem (GYE) is a vestige of wild America. Embracing approximately 18 million acres in and around Yellowstone National Park, the GYE includes some of our nation’s most cherished landscapes and diverse wildlife, including rare trumpeter swans, wolves, one of the last viable grizzly bear populations outside of Alaska, and the largest elk and free-roaming bison herds in North America. Approximately 31,000 square miles in size, Greater Yellowstone contains both our country’s first national park, Yellowstone, and our first national forest, the Shoshone. Established in the late 1800s, Yellowstone and the Shoshone are the wild anchors of Greater Yellowstone, which also encompasses another iconic national park, Grand Teton, as well as five additional national forests in three states and two national wildlife refuges.
