Grand Teton protects the youngest range in the Rocky Mountains — a 40-mile wall of granite peaks that climbs 7,000 ft from the floor of Jackson Hole with no foothills in front of them, producing the most abrupt mountain skyline in the contiguous US. The park covers 310,000 acres directly south of Yellowstone, joined by the John D. Rockefeller Jr. Memorial Parkway, and shares the same wildlife corridor — bison, moose, grizzly and black bears, wolves, elk. Established in its current form in 1950, today it draws around 3.4 million visitors a year. From the west, I-15 Exit 119 in Idaho Falls puts you on US-26 east; from the south, I-80 Exit 99 in Rock Springs leads 175 miles north on US-191 to Jackson. Effective January 1, 2026, Grand Teton is on the new $100 nonresident-surcharge list (the eleventh park added).
