Year-round
Okay, adventure seekers, listen up! Mill Creek Summit in central Idaho's Salmon-Challis National Forest is calling your name! This isn't your average Sunday drive; it's a 43.6-mile (70.16km) trek back in time on the historic Custer Motorway (aka Mill Creek Road or Yankee Fork Road). This old toll road, County Road 070, connects Challis (off US Hwy 93) to Sunbeam (on ID State Hwy 75).
Clocking in at 8,809 feet (2,685m), this pass is a beast! Expect a mostly dirt and gravel road with some seriously narrow spots and grades hitting a maximum of 12%. Open from July to October, this route offers stunning views, but be warned: low-clearance vehicles and trailers might want to sit this one out. The road can get washboarded, making for a bumpy ride. Get ready for an unforgettable off-the-beaten-path experience!

🇺🇸 Usa
Okay, Texas road trip fans, listen up! If you're looking for a real adventure in Jeff Davis County, you HAVE to check out Whitetail Mountain. This isn't your average Sunday drive – we're talking a 6.2-mile (10km) off-road odyssey that climbs to a whopping 7,270 feet (2.216m) above sea level. Forget smooth asphalt; this baby is all unpaved, so a 4x4 is definitely your best friend here. Fair warning: there's a gate, so check access before you go. But trust me, the views from the top are worth the bumpy ride. Get ready for some seriously epic scenery!
moderateBadlands Loop Road, an adventurous photogenic drive in SD
🇺🇸 Usa
Okay, road trip fans, listen up! You HAVE to check out the Badlands Loop Road (SD 240) in South Dakota. It straddles Jackson and Pennington counties and is totally paved. This isn't a long haul at just 38 miles, starting and ending at I-90, but trust me, you'll want to set aside way more than an hour. The road climbs to a peak of 3,231 feet, so expect some steep sections! But the views? Totally worth it! Think incredible buttes, cliffs, and those signature multi-colored spires of the Badlands National Park. There are 14 official overlooks, and seriously, each one is a photo op waiting to happen. This road feels like another planet, with unique rock formations mixing with native grasslands, offering plenty of chances to see bison, deer, coyotes, and more. It's an engineering marvel and a visual feast. Breathtaking vistas, clean air, and a serene atmosphere. Don't miss it!
extremeWhere is Sierra Negra?
🇲🇽 Mexico
Okay, picture this: you're in Puebla, Mexico, itching for an adventure, and someone whispers about Sierra Negra. This extinct volcano, also called Cerro La Negra, is nestled near Veracruz in the Pico de Orizaba National Park. The views? Absolutely insane! But here's the catch: the road to the top, also known as Tliltépetl or Volcán Atlitzin, is not for the faint of heart. Forget smooth tarmac – it's all unpaved and seriously bumpy. You absolutely NEED a 4x4 to even think about tackling it. Speaking of tackling, this road is twistier than a pretzel! Hairpin turns galore as you wind your way up. And steep? Oh yeah, some sections hit a crazy 17% gradient. From the town of Atzitzintla, it's about 18.5 km (11.5 miles) to the summit, climbing a staggering 1,849 meters. That's an average gradient of almost 10%! Heads up though: this is serious altitude. We're talking 4,576m (15,013ft) above sea level! The air gets thin, and the weather can be unpredictable. Plus, this road isn't generally open to the public. You need special permission to drive it. But if you can pull it off, you'll be rewarded with views and bragging rights that are out of this world. Oh, and you can check out the Large Millimeter Telescope at the summit, the biggest of its kind!

🇨🇦 Canada
# Alberta Highway 40: A Must-Drive Alpine Adventure If you're looking for one of Canada's most stunning road trips, Highway 40 in Alberta absolutely delivers. This epic 1,021 km (634 miles) stretch winds from the small mountain town of Coleman in the southwest all the way up to Grande Prairie in the northwest—and trust me, every kilometer is worth it. You'll know this route by a few names: Highway 40, the Bighorn Highway, or the Kananaskis Trail. Fair warning though—some sections are paved while others are gravel, so come prepared for a bit of variety. The real showstopper? Highwood Pass, where you'll summit at an impressive 2,217m (7,273ft)—the highest elevation of any highway crossing in Canada. You'll be cruising right near the treeline, surrounded by snow patches that stubbornly stick around even during summer months. It's genuinely spectacular, but heads up: this section closes annually from December 1 to June 14, and winter weather can shut things down without warning elsewhere on the route. What makes this drive truly special is the wildlife and scenery. Throughout your journey, you'll spot bears, elk, moose, mountain goats, and coyotes roaming against a backdrop of jaw-dropping mountain vistas. The Canadian Rockies frame every turn, making this one of those road trips that'll have you stopping constantly for photos. Whether you're after a day trip or a longer adventure, Highway 40 captures the raw beauty of western Alberta in a way that'll stay with you long after you've returned home.
