# Col del Sommeiller
Want to tackle one of Europe's most epic high-altitude drives? Meet Col del Sommeiller, sitting pretty at 2,993m (9,819ft) on the French-Italian border in the Alpi Cozie. This isn't just any mountain pass—it's a serious alpine adventure.
The journey starts in Bardonecchia, Italy, and climbs 26 kilometers of pure mountain magic. You're rewarded with hairpin after hairpin, stunning alpine dams, and a jaw-dropping turquoise lake waiting for you at the summit. The whole thing gains 1,711 meters with an average grade of 6.5% (though it can hit a gnarly 19% in places). Fair warning: the views are genuinely spectacular, but the road demands respect.
Here's the deal with the drive: Only the first 6km is paved—and not even well-paved. The remaining 20km is rocky, unforgiving terrain that'll test your driving skills. You'll want a 4x4 for this one, no question. The surface stays mostly drivable until you hit the final stretch near the summit, where things get pretty gnarly and disconnected.
The pass carries some serious history too. It's named after Germain Sommellier, the engineer behind the legendary Fréjus railway tunnel that opened in 1871—and yep, you start your climb right where that tunnel begins.
A heads-up: this road is brutally seasonal. Expect it to be completely closed from late October through late June, with snow clearing not happening until late July. Even when it's open, Bardonecchia restricts traffic on Thursdays from July through September to protect the road.
This is pure, unfiltered mountain driving. Bring your A-game and a solid vehicle.

extremeWhich Roads in Crete Have the Most Hairpin Turns?
🇬🇷 Greece
# Crete's Epic Mountain Roads Welcome to Crete, Greece's largest and most mountainous island—a place where dramatic peaks plunge straight toward sparkling coastlines, leaving just slivers of land in between. It's basically nature showing off. The interior roads here are absolutely *wild*. We're talking tight hairpin turns that'll have your knuckles white on the steering wheel, all winding through impossibly steep terrain to connect tiny mountain villages that feel like they're perched on the edge of the world. These aren't just roads; they're engineering feats that'll make you question whether your rental car is up for the challenge (spoiler: it probably is, but your nerves might not be). The payoff? Some of the most breathtaking panoramic views you'll ever experience. Every switchback reveals another jaw-dropping vista of rugged cliffs, ancient gorges, and that stunning Cretan light hitting the landscape just right. If you're the type who gets an adrenaline rush from ambitious driving and want to see the *real* Crete—the untamed, gorgeous interior that most tourists miss—these mountain passes are calling your name. Popular routes include Libadas to Koustgerako, the Kouroutes to Toumpotos Prinos run, Simi through Omalos Viannou, and several other spine-tingling climbs through this spectacular island. The Therisos Gorge offers another legendary drive, while those seeking even more adventure can venture north to Mount Oeta in Central Greece.
hardCol de la Lariée: Driving the 1,964m unpaved military border track
🇫🇷 France
# Col de la Lariée: A Wild Alpine Adventure Just northwest of Basera Pass sits Col de la Lariée, a rugged 1,964m (6,443ft) mountain pass that sits right on the France-Italy border. This isn't your typical scenic mountain drive—it's a genuine slice of Alpine history and challenge rolled into one. This pass connects the Alpes-Maritimes in southeastern France with Piedmont's Province of Cuneo in Italy, following an old military route that traces the watershed line through the Ligurian Alps. On a clear day, the views are absolutely stunning—jagged limestone peaks dominating your windshield and glimpses of the Mediterranean coast in the distance. And yes, you'll spot remnants of early 20th-century military fortifications scattered around, adding a fascinating historical layer to the drive. Now, let's talk about what you're actually getting into. This isn't paved—it's a rough-and-tumble gravel and crushed rock track that demands serious respect. We're talking narrow, exposed sections with steep drops and zero guardrails. A high-clearance 4x4 is basically essential here. After rain, the loose rocky surface gets slippery fast, and patches of thin mountain soil turn into genuine mud. You'll need nerves of steel and excellent vehicle handling to navigate this properly. The stretch itself is surprisingly short—just 650 meters (0.4 miles) from Passo di Tanarello—but don't let that fool you. At this elevation with this terrain, those few hundred meters pack serious intensity. The pass typically opens late June and closes by October when heavy snow and ice shut down the high ridgelines. It's a short but genuinely technical section that connects the historic military roads linking Italy and France.

moderateSobrón Canyon road, a Spanish hidden gem
🇪🇸 Spain
# Sobrón Canyon Road Ready for one of Spain's most breathtaking drives? The Sobrón Canyon road is an absolute gem that winds through some seriously stunning landscape right on the border between the Basque Country and Burgos province in northwestern Spain. This fully paved route (A-2122 and BU-530) hugs the Sobrón reservoir for the entire 17.7 km (10.99 miles), carving through a dramatic gorge that the Ebro river spent centuries sculpting. The reservoir itself dates back to 1960, adding to the scenic charm of the area. Stretching from Barcina del Barco in Burgos to Puentelarrá in Álava, this route squeezes between the Montes Obarenes and Sierra de Árcena mountain ranges. Fair warning: the road gets narrow in sections, but that's part of what makes it so special. You'll be rewarded with jaw-dropping views at nearly every turn—seriously, bring your camera.
