Driving Scenic Byway 12 is an adventure in itself. The route climbs and descends steep grades ranging from 8% to 14%, winding through mountains, forests, and dramatic canyon country. The most famous section is the exhilarating "Hogback," a narrow ridge where the road hugs the spine of the landscape for approximately one mile. With steep drop-offs on both sides and panoramic views stretching for miles, this unforgettable stretch delivers one of the most thrilling and scenic driving experiences in the American Southwest.
Utah Scenic Byway 12: RV Driving Caution

Big Rig RV Route Decision: The choice ultimately comes down to your comfort level behind the wheel. When traveling between Bryce Canyon and Torrey in a big rig, you'll face a choice: take scenic Highway 12 and experience one of the most spectacular drives in America, or choose a more relaxed route with fewer driving challenges.
Scenic Byway 12 showcases some of the most incredible landscapes in the Southwest, but it isn't for every driver. The route features steep grades, some of which are listed below, that require engine braking to control speed on the descent and, if traveling west, steep uphill grades. While thousands of RVers travel this route each year without issue, it can be intimidating for those who experience "white-knuckle" driving.
If you're uncomfortable using engine braking to control speed on mountain grades, consider taking the alternate route. From Bryce Canyon, travel north on Highway 89, east on Highway 62, and then south on Highway 24 into Torrey. Surprisingly, the mileage is nearly the same, but the drive is generally less demanding and often more enjoyable for those who prefer a leisurely pace.
Mile Marker 5: Highway 12 travels under two Red Canyon Arches. The stated height is 13’6” (if you are tall, wait for no travel and drive down the middle).
Mile Marker 69: Stop at the “Head of The Rocks” Overlook. The Escalante Canyon view, as far as you can see, is a maze of deep, winding canyons and colorful slickrock. From Bryce Canyon, it’s a 14% grade down to the river.
Mile Marker 79: Welcome to “The Hogback.” Travel up the 14% grade out of the canyon to the top of the ridge. For one mile, the road winds along the top of the ridge, just wide enough to fit a two-lane road, with treacherous drop-offs on either side. Plenty of places to stop.
