AAA Editor Notes
Yellowstone-Grand Teton Scenic Loop is an approximately 263-mile scenic drive in eastern Idaho, northwestern Wyoming and a small portion of south-central Montana. The route encompasses the Teton and Mesa Falls scenic byways as well as Yellowstone and Grand Teton national parks.
Starting in Victor, Idaho, the 47-mile first segment follows SRs 33 and 32 northwest to Ashton, Idaho, along the Teton Scenic Byway, from which the Teton Mountains can be viewed to the east.
As you take the Mesa Falls Scenic Byway north to Island Park, Idaho, on the 35-mile second segment, you'll pass Upper Mesa Falls and Harriman State Park, both to the west.
Following US 20 north on the 28-mile third segment, you'll reach Henry's Lake State Park and then head east through touristy West Yellowstone, Mont., which is situated at Yellowstone National Park's west entrance (hence the name).
Most of the 98-mile fourth segment traverses the western side of Yellowstone National Park. After exiting the park via the south entrance (which is also the north entrance to Grand Teton National Park), you'll drive over the Continental Divide, through pine and fir forests and past Jackson Lake. Recreational opportunities abound at Jackson Lake and throughout Grand Teton National Park.
The 30-mile fifth segment begins at the Moran junction. US 26/191, with the Tetons on the northern side and pastures with buffalo and elk on the southern side, has numerous pull-offs with informational plaques. The route passes the National Elk Refuge, where you can observe elk from boardwalks and decks, and then enters Jackson Hole.
On the 25-mile final segment of the trip, you'll head back to Victor via SR 33, which winds through Caribou-Targhee National Forest over dramatic mountains with hairpin turns.
Note: Mesa Falls Scenic Byway is closed from mid-November to late April; take US 20 toward Island Park as an alternate route. The road between Yellowstone National Park's west and south entrances also is closed from mid-November to late April.
