Year-round
Col du Sanetsch is a seriously impressive high mountain pass sitting pretty at 2,250m (7,381ft) in Switzerland's Valais canton. We're talking the southwestern part of the country, nestled in the western Bernese Alps right at the base of Glacier de Tzanfleuron. Fair warning though: this is a road reserved for buses and authorized vehicles only—private cars aren't allowed.
Starting from Conthey, the 25.9 km (16.09 miles) paved Route du Sanetsch is an absolute beast. The climb kicks off with a steep push through vineyards, then suddenly you're surrounded by gorgeous forest and cascading waterfalls. But here's where things get wild: the final stretch features a massive 800m tunnel that's genuinely creepy—pitch black with just tiny light sensors guiding you through. It's long, damp, and kind of unsettling, though there are a few openings where you can catch glimpses of the landscape or catch your breath.
This isn't your average climb. Locals proudly call it the Swiss answer to the legendary Passo Stelvio, and for good reason. Some sections hit a punishing 14.5% gradient, making it one of Valais's most demanding routes. Plan on 45 to 60 minutes of driving time without stops.
The pass only opens June through September, so timing matters. Once you reach the summit, there's a huge parking lot waiting, but brace yourself—the wind up there is absolutely relentless. On a clear day, you'll catch stunning views of the Diableret glacier and the sparkling Lac de Sanetsch below. Absolutely worth the climb.

hardDriving the Wild Unpaved Road to Colombardo Pass in Piedmont
🇮🇹 Italy
Passo del Colombardo is a high mountain pass sitting at 1,898m (6,227ft) above sea level in the Metropolitan City of Turin, Italy. Nestled in the Piedmont region of northern Italy, this Alpine gem is home to a charming little church at the summit called Santuario della Madonna degli Angeli. The pass gets its name—Col de Colombardo in French—from a distinctive wind that sweeps in from Lombardy. Once you reach the top, you'll find several minor unpaved roads branching off to some seriously scenic spots like Alpe della Portia, Alpeggio Tomba di Matolda, Truc Muandette, and Alpe del Rat. Here's the real deal: the road up is mostly unpaved, recently renovated, but don't let that fool you. It's narrow, steep as they come, with some sections hitting gradients of 18.5%—no joke. Winter? Forget about it. The road closes when the snow rolls in. If you're starting from Forno, the village to the north, you're looking at a 9.6 km (5.96 mile) push to the summit. Over that distance, you'll gain a solid 1,024m of elevation, averaging a 10.66% gradient. It's a challenging climb that rewards you with stunning Alpine scenery and that beautiful sanctuary waiting at the top. Definitely one for the bucket list if you're into mountain driving.
extremeWhere is Pico Mirandiella located?
🇪🇸 Spain
Okay, picture this: you're in northern Spain, right on the border of Teverga and Somiedo, in the Asturias region. You're about to tackle Pico Mirandiella. Locals whisper that this climb is "simply brutal," and, trust me, they're not kidding. We're talking about a spot nestled within the Cantabrian Mountains, inside the protected Somiedo Natural Park. You'll be towering above the famous Puerto de San Lorenzo, a cycling hotspot. Alright, the road itself... well, "road" might be a generous term. It's a short, sharp 1.9 km kick in the teeth from Puerto de San Lorenzo. Don't let the distance fool you; you’re gaining some serious elevation. We are talking a crazy steep incline. Word to the wise: unless you’re a park ranger, a farmer, or there to fix the communication tower up top, access is restricted. And even if you *are* authorized, you're going to need a serious 4x4 for this beast. Most of the track is rocky and unpaved, though you might find some concrete. It's a rough and raw ride. Why bother? The views, my friend, the VIEWS. A full 360-degree panorama of the Cantabrian Mountains and the deep valleys of Somiedo will reward you. Heads up, this climb is not for the faint of heart. Winter brings deep snow, so aim for late spring to early fall. And always, ALWAYS check the weather. This mountain plays by its own rules.
extremeHow long is the F26 Road (Sprengisandsleið) in Iceland?
🇮🇸 Iceland
Okay, picture this: you're in Iceland, craving adventure, and someone whispers "F26." This isn't your average Sunday drive. We're talking about the Sprengisandsleið, a legendary highland gravel road smack-dab in Iceland's Southern Region. This beast stretches for 232 km (144 miles) through the Sprengisandur area, a desolate plateau stuck between the Hofsjökull and Vatnajökull glaciers. It's the longest of Iceland's infamous F-roads, a proper challenge that hasn't changed much since medieval times. Just imagine the stark, raw scenery as you roll past Hekla volcano, marking the southern entrance. But wait, there's more! This road climbs to a lofty 861m (2,824ft), making it one of Iceland's highest. It usually opens late June, but Mother Nature calls the shots. Keep an eye on the weather, because rain and heat can turn those glacial rivers into raging monsters. Thunderstorms? Lightning? Yeah, those are on the menu too. Speaking of rivers, get ready to ford some! You'll encounter several unbridged crossings, and the water can get up to a meter deep. Daytime's cool, but nighttime? That's when the road's said to get a little… haunted. Gas is non-existent here, and the stations at Hrauneyjar and Goðafoss are a whopping 240km (149 miles) apart. Don't be that unprepared driver begging for fuel at Nýidalur! The Hagakvislar river, near the Nýidalur hut, is the main event. It's unpredictable, swelling with rain and a strong current. River crossings need experience. Don't go solo or during heavy rain – it's a recipe for disaster. Wait for another vehicle, assess the current, depth, and riverbed. Remember, rental car insurance usually doesn't cover water damage. Big potholes, ruts, boulders – this road is rough. You'll need a serious 4x4 with good clearance. Forget your cute compact car. The F26 cuts through Iceland's heart, its empty, stunning interior. Be prepared to be alone – it's remote and not heavily trafficked. Think endless grey sand, rocks, and glaciers looming in the distance. The enduring image? Nothingness. So, if you're looking for a wild, unforgettable Icelandic experience, the F26 is calling your name. Just be prepared!
hardCol de Plantara
🇫🇷 France
Okay, so you're heading to the Drôme region in southeastern France? Sweet! You absolutely HAVE to check out Col de Plantara. This mountain pass tops out at a cool 1,002 meters (that's about 3,287 feet). The road, known as the D627, is paved, but be warned – it's a bit of a rollercoaster! Think narrow, steep stretches that will definitely keep you on your toes. But hey, that's part of the adventure, right? And get this – you'll even pass by the Fort de la Grande Maye. The scenery is killer, so keep your eyes peeled (but on the road mostly, haha). It’s a must-do if you’re in the area!
