John D. Rockefeller Jr. Memorial Parkway Professional Review and Guide
"Used as an entryway to either Yellowstone or the Tetons, this short drive begins at the second-most traveled gateway to Yellowstone National Park: the South Entrance (West Yellowstone is the busiest.) The 6.8-mile route to Grand Teton National Park is bordered by thick lodgepole pines, the Snake River, creeks, campgrounds, and rugged backcountry. Depending on the traffic, this drive can be a quick jaunt or a slow crawl.
Shortly after exiting Yellowstone, look across the meadow to the east to see steam rising about half a mile away. These hot springs are rather easy to walk to, especially at the end of summer when the Snake River is low and easy to cross. More hot springs simmer another half mile beyond the first ones. As you venture farther, you get a beautiful view of the north end of the Tetons. Nearby points of interest: Hot springs, Huckleberry Mountain, Grassy Lake Reclamation Road."
