Amarillo, the largest city in the Northern Texas Panhandle, was established in 1887 as a trading center in an area of large cattle ranches. The still-operating 1876 JA Ranch is the oldest ranch in the Panhandle region. Amarillo is known for cowboy culture and U.S. Route 66 roadside attractions, including the Cadillac Ranch and the Big Texan Steak Ranch restaurant. Downtown, the Sixth Street Historic District is a hub of dining and antique shopping. Just outside town, Palo Duro Canyon State Park highlights the second-largest canyon in the U.S. It’s a place of great scenic beauty with many miles of hiking trails, 10 different mountain bike trails, and a zipline that crosses the 800-foot-deep canyon.
