Though not near the sea, you’ll pedal toward the “Lighthouse” at Palo Duro Canyon State Park, home to the second largest canyon in the United States. A landscape of colorful rock sheers, abundant cacti, sticky red dirt, and sandy creek beds, the park offers many options for explorers, both on foot and two wheels. Bicycle enthusiasts can explore more than 30 miles of trails; road bikes must stick to the 15 miles of paved roads, and steer downhill toward the canyon. (Within the park you'll find more trails, including bypass options.) Don’t miss the signature route, the Lighthouse Trail, named for the park’s natural wonder—a soaring, rainbow-hued rock column known to geologist as a hoodoo.
