There are pictographs all around the Southwest, many easily accessible by vehicle. But it takes a hike—and a good one at that—to reach what is arguably the most famous rock art display in the country.

Visitors come to Great Smoky Mountains National Park for many reasons. They want to hike the more than 70 miles of the rugged Appalachian Trail that meander through the park, to camp in its dense forests, to cool off in one of its many streams, or to take a leisurely drive along the scenic Newfound Gap Road that crosses the heart of the park to connect Tennessee with North Carolina. Regardless of the reason, they come—in droves. Every year, 8-10 million people travel to the Smokies, making it the most-visited national park in the country.

Imagine: An open road, the top rolled back, the windows down, pastoral views drifting by, with your favorite tunes streaming from your stereo. Once the Greatest Generation refocused on home life after World War II, they were able to, “See the USA in your Chevrolet.” Highways and byways meant relaxation, recreation, all with a backdrop of roadside nostalgia.

You can hike this Yellowstone National Park trail for a day, with a turnaround at Lone Star Geyser, or you can continue on down to Shoshone Lake for a wonderful three-four day retreat into the park’s backcountry.
