Arbuckle Mountains — US-77

Oklahoma's Cherokee Hills National Scenic Byway (designated 2009) runs 84 miles along State Highway 10 from Gore north through Tahlequah to West Siloam Springs on the Arkansas border. The southern half traces the eastern shore of Lake Tenkiller through forested Cookson Hills, while the northern stretch parallels the clear waters of the Illinois River past stone bluffs and dense Ozark foothills. OK-10 through the Tahlequah corridor is noted for long, flowing sweepers, limited sight lines around blind wooded corners, and consistent tree canopy. The Cherokee Nation capital at Tahlequah is on-route.

US-412 between Orienta and Fairview in Major County traverses roughly 25 miles of selenite-capped mesas known as the Glass (or Gloss) Mountains, where crimson and black mesa walls rise abruptly from the surrounding wheat-field prairie. The gypsum and selenite crystals covering the mesa slopes reflect sunlight and create a visual signature unique in the southern plains. Gloss Mountain State Park, on a mesa just west of Orienta, provides a walk-up overlook accessible from a roadside pull-out. The highway is a long, flowing two-lane with minimal traffic and unobstructed views across northwest Oklahoma.

Cathedral Mountain at Gloss Mountain State Park in Major County rises 150–200 feet above the surrounding prairie on US-412 between Fairview and Enid. The selenite-capped mesas that give the Glass/Gloss Mountains their name flash silver in direct sun. A short staircase trail (1.2 miles round-trip) climbs Cathedral Mountain for a panoramic view over Lone Peak Mountain and the flat wheat country of northwest Oklahoma. Free access, year-round. The park's roadside pull-out makes it a quick spontaneous stop mid-ride.
