Okay, road trip fans, let's talk Bannock Pass! This beauty straddles the Montana/Idaho border, clocking in at a lofty 7,684 feet above sea level.
So, "Bannock"? That's a nod to the Bannock Native American tribe who used this route way back when, connecting Montana's buffalo lands to the Snake and Salmon River fishing havens. Think of it as the original cross-state shortcut between the Lemhi River Valley and Horse Prairie!
You'll find this pass nestled high in the Beaverhead Mountains, part of the stunning Bitterroot Range in the Rockies. The southern side is known as Idaho State Highway 29 (ID-29), morphing into Montana Secondary Highway 324 (MT-324) as you head north.
The good news? It's mostly paved and pretty wide, with a manageable max gradient of 7.0%. The slight catch? Expect about 10 miles of gravel connecting those smooth sections.
Bannock Pass runs for 47.8 glorious miles, stretching west to east from Leadore, Idaho, all the way to the I-15, north of Red Rock, Montana. It sits right on the Continental Divide, so expect some seriously epic views.

extremeHow long is Pleasant Canyon Road?
🇺🇸 Usa
Okay, buckle up for the Pleasant Canyon/South Park 4x4 Loop in Death Valley National Park! This isn't your grandma's Sunday drive. We're talking a 23-30 mile, exclusively 4x4 adventure that kicks off near Ballarat, climbing from 1200 feet to a whopping 7100 feet at Roger's Pass. Now, most of the loop is pretty chill, but Pleasant and South Park Canyons can get gnarly. Think water damage, shifting rocks, and super steep sections. If you're in a stock SUV, you might be sweating bullets, especially heading east in South Park Canyon. It's rocky, it's rough, but it's a loop that'll bring you back down into Panamint Valley. This isn't just some random trail, though. It's got history! The guys who built the Thorndike Mine carved this road out for mules hauling ore. Speaking of mines, you'll see a ton along the way. They look cool, but stay out – they can be super unstable. Of course, Death Valley is, well, Death Valley. It gets HOT. Like, record-breaking hot. Hydrate like your life depends on it (because it kinda does), avoid hiking midday, and prep for anything. If the car goes kaput, stick with it. Rattlesnakes, scorpions, and spiders are also out there. And seriously, avoid canyons if it's raining – flash floods are no joke. Cell service is spotty, so be prepared.
hardWhere is Crystal Mill?
🇺🇸 Usa
Okay, picture this: You're just outside the charming little town of Marble, Colorado, ready for an adventure. The destination? The legendary Crystal Mill, that iconic wooden structure perched dramatically above a waterfall. Now, getting there is half the fun – and a bit of a challenge! Crystal Mill Road (aka County Road 3) is about 5.6 miles of pure, unadulterated off-road terrain. Forget pavement – this is a rugged, one-lane dirt track with narrow, rocky, and seriously steep bits. This is NOT a drive for your average sedan or a timid driver. You'll want a proper 4x4 and some off-road experience under your belt. The road's only open during the warmer months (usually late June/early July through late October) because those Rocky Mountain winters are brutal. As you wind your way along the Crystal River, the views are insane. Think towering peaks of Whitehouse Mountain and the Sawatch Range filling your windshield. Just before reaching the ghost town of Crystal, you will see the Mill. Seriously, this place is a photographer's dream come true. Just remember that cell service is spotty, so plan accordingly, and definitely don't get caught out there after dark. It's worth every bump and bruise.
moderateWhere is Martis Peak?
🇺🇸 Usa
Okay, picture this: You're cruising in California, itching for insane views of North Lake Tahoe and the Truckee area. I've got the spot – Martis Peak! Tucked away in the Tahoe National Forest, not far from the Nevada border. So, how do you get there? You'll hop onto Martis Peak Road. It climbs to a whopping 8,700 feet above sea level in just under 4 miles. The road starts off paved, but don't get too comfy – it turns to partial dirt closer to the top. Expect curves and a narrow path, so keep your eyes peeled for oncoming traffic. What's waiting for you at the top? Get ready for some serious panoramic action. There's an old fire lookout, originally built in 1914, keeping watch during fire season. The views? Unbelievable. Think distant mountains to the north, Castle Peak to the northwest, and the entire Lake Tahoe basin. You'll also get an amazing birds-eye view of Truckee. Word of warning: this road is usually closed in winter, due to its location in the Sierra Nevada mountain range. You might find snow, but it's open for hiking.
hardCampito Mountain
🇺🇸 Usa
Okay, adventure seekers, let me tell you about Campito Mountain in California's Mono County! This beast tops out at a whopping 10,807 feet, making it one of California's highest drives. Now, fair warning: this isn't your Sunday cruise. We're talking gravel and rocky terrain all the way. You'll be on Campito Mountain Road, a proper 4x4 track that’s usually open from June to October, depending on the snow. This isn't for the faint of heart! Expect some seriously steep sections, and yeah, a slip could have consequences. Plus, the weather up there is wild, so be prepared for anything. But if you’re up for the challenge, the views are absolutely unreal. Get ready for some high-altitude thrills!
