Year-round
Alright road trip warriors, let's talk O'Neil Pass! This beauty clocks in at a cool 6,712 feet above sea level, making it the highest paved road in South Dakota. You'll find it snaking through the Black Hills National Forest in the western part of the state.
The whole thing is paved (thank goodness!), and it's actually part of U.S. Route 85. But don't think it's a boring cruise! This stretch throws in some serious climbs, hitting a 7% gradient in spots to keep things interesting.
The pass itself runs for about 25 miles, starting near Cheyenne Crossing, South Dakota and ending near Four Corners, Wyoming. Keep your eyes peeled for wildlife – they love this area! And a word to the wise: winter can get dicey with ice and snow on those curves.
Just past the summit, you'll find Trailshead Lodge. So if you're looking for a cozy cabin or some snowmobiling action, you know where to stop!

extremeSacramento Peak
🇺🇸 Usa
Okay, adventurers, listen up! If you're cruising around south-central New Mexico in Otero County and have a hankering for heights, Sacramento Peak is calling your name. We're talking a whopping 9,262 feet above sea level! You'll be winding your way up the Sunspot Highway (NM Hwy-6563) through the Sacramento Mountains. The road's paved, but get ready for some seriously curvy action and a fairly steep climb. Once you conquer the ascent, you'll be greeted by incredible views and a collection of observatories perched right at the top. Just a heads-up – winter brings the white stuff, so be prepared for snow if you're visiting then. Get ready for an unforgettable ride!
hardFreds Mountain
🇺🇸 Usa
Okay, thrill-seekers, listen up! Freds Mountain in Teton County, Wyoming is calling your name, but this ain't your average scenic drive. We're talking about a gnarly climb up to 9,855 feet! You'll find this beast within the Caribou-Targhee National Forest, and let me tell you, the road is ROUGH. Think gravel, rocks, and a whole lotta "tippy and bumpy." This is actually the service road for the Grand Targhee Resort's chairlift, so conditions are constantly changing, and one wrong move could have serious consequences. Seriously, winter hangs around FOREVER up here, so mid-summer is probably your only safe bet. Scope out the road ahead before you commit, because things can get dicey quick. You'll absolutely need a 4x4 and some serious off-roading skills. Patience is key, and if you're afraid of heights, maybe skip this one. This is an adventure for experienced drivers only – leave your Sunday drivers at home! But if you're up for the challenge, the views are totally worth it.
moderateNavajo Mountain
🇺🇸 Usa
Okay, buckle up, adventure seekers! We're heading to Navajo Mountain in Utah's San Juan County, a real hidden gem peaking at 10,347 feet. The road up? Let's just say it's not for the faint of heart. Think gravel, rocks, and a whole lotta bump and sway. Winter? Forget about it. This beast is usually snowed in. Seriously, you'll need a 4x4 and some serious off-road skills to tackle this one. And if you're scared of heights, maybe sit this one out. It's a steep climb. Rainy days turn the road into a muddy mess, making things even trickier. The reward? Killer views! Just be aware, the very top is dotted with communication towers, so it's not exactly a pristine wilderness up there.
hardCarrizo Mountain
🇺🇸 Usa
Okay, adventure junkies, listen up! If you're anywhere near Imperial County, California, you HAVE to check out the Carrizo Mountain Trail. This isn't your Sunday drive – we're talking a seriously rugged climb up to 2,168 feet in the Coyote Mountains. The road, Carrizo Mountain Trail, itself? Think gravel, rocks, and maybe a few prayers. A 4x4 is an absolute MUST. Seriously, don't even think about attempting this in your Prius. Oh, and if you're afraid of heights, maybe grab a buddy to drive. Keep in mind this area is usually closed for part of the year, roughly January through June. Expect a nail-biting, narrow path with some serious drop-offs – one vehicle at a time, folks! It's steep, rocky, and loves to lean outwards, adding to the thrill. After rain, things get extra dicey, so watch out for loose gravel surprises. An old mine road winds through the colorful Painted Gorge, taking you almost to the top. Trust me, though, the views from the summit are worth every white-knuckle moment. You'll see the whole California Desert spread out before you!
