This Amarillo institution serves a hearty menu of sandwiches, ribs, chicken fried chicken, and steaks and even houses an on-site brewery. But you’re here for the 72-Ounce Steak Challenge. Participants face off against a full table of food, including shrimp cocktail, salad, bread and a baked potato in addition to that gargantua gut-buster. If you polish your plate within an hour, the whole thing is on the house.

Home to the second largest canyon in the country, Palo Duro Canyon State Park is well worth a 30-minute southbound detour. Cruise into the park for a quick look at what’s considered the Grand Canyon of Texas, and if you have the time, lace up your boots and spend a few hours exploring the rugged terrain. Breathe in the fresh air as you traverse trails on foot, bike, or horseback, or pack it in for night under the stars at one of the area’s many campsites (or glampsites).

Back on Route 66, you have one more stop before officially exiting Amarillo’s sprawl. Cadillac Ranch is a public art installation featuring 10 heavily-graffitied vintage cars buried nose-down in a roadside pasture and positioned at the same angle as the Great Pyramid of Giza. Created in 1974 by a San Francisco art collective and funded by a local millionaire, the exhibit encourages visitors to leave their own marks on the brightly colored cars.

Opened in 1928, the outpost once operated as a 24-hour fuel-up spot for hungry travelers. Over the decades, the property has expanded and even starred in the Pixar movie Cars as Flo’s V8 Cafe. It remains a popular destination for breakfast, lunch, and, most famously, freshly-baked sweet treats.

The first stop on your swing through the Panhandle is Groom, a small town with two claims to fame—or roughly one per 300 people. The Leaning Tower of Texas is an old water tower tilted at a striking 10-degree angle, and while it may appear ready to crash toward the earth, it’s been standing strong for decades. It’s the brainchild of Ralph Britten, who used the eye-catching structure as a marketing ploy to draw passersby to his truck stop and restaurant.
