Explore the Rockefeller Parkway and Flagg Ranch
Located at the heart of the Greater Yellowstone Ecosystem, the John D. Rockefeller, Jr. Memorial Parkway connects Grand Teton and Yellowstone national parks. The late conservationist and philanthropist John D. Rockefeller, Jr. made significant contributions to several national parks including Grand Teton, Acadia, Great Smoky Mountains, and Virgin Islands.
In 1972 Congress dedicated a 24,000-acre parcel of land as John D. Rockefeller, Jr. Memorial Parkway to recognize his generosity and foresight. Congress also named the highway from the south boundary of Grand Teton to West Thumb in Yellowstone in honor of Rockefeller.
The parkway provides a natural link between the two national parks and contains features characteristic of both areas. In the parkway, the Teton Range ramps down a gentle slope at its northern end, while rocks born of volcanic flows from Yellowstone line the Snake River and form outcrops scattered atop hills and ridges.Flagg Ranch is situated two miles south of Yellowstone and six miles north of Grand Teton in the John D. Rockefeller, Jr. Memorial Parkway. Flagg Ranch sits near the banks of the northern section of the Snake River. A variety of activities and services can be found at Flagg Ranch. Stay the night at the lodge or campground, grab a meal, fish the river, or go for a hike.
