# 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.

moderateWhere is Col de la Traversette?
🇫🇷 France
Okay, adventure seekers, listen up! Let's talk about the legendary Col de la Traversette, a high-altitude beast of a pass nestled way up in the French Alps (Savoie department to be exact). We're talking 2,369m (7,772ft) above sea level! Some say this is the very spot where Hannibal and his elephant squad marched into Italy. You'll find this gem in the Auvergne-Rhône-Alpes region, practically straddling the Italian border, just south of Little St Bernard Pass. Now, don't expect a smooth ride. This road is strictly unpaved – think old military track territory, built for 4x4s and enduro bikes only. Why brave it? Well, the climb is surprisingly doable, and the views are simply breathtaking. Plus, you're standing on a piece of history! Imagine Hannibal himself leading his army, elephants and all, through this very pass into Italy back in 218 BC. Plus, it's on the way to Le Fort de la Redoute, an old mountain fort with some stunning history of its own. Heads up, the fort is sadly closed due to collapse danger. Keep in mind, winter is a no-go. This road, set high in the Cottian Alps, becomes totally buried in snow. Ready for a challenge? Starting from the D1090 road, it’s a 2.5km climb to the top. But hold on tight, because you’re gaining 324m of elevation along the way! The average gradient is a leg-burning 12.96%, with some sections hitting a crazy 30%.
hardWhere is Oituz Pass?
🇷🇴 Romania
Okay, picture this: You're cruising along DN11, Romania, winding your way up to 868 meters (2,847 feet) above sea level. This isn't just any road; this is Oituz Pass, a seriously historical shortcut! Spanning 12.2 km (7.58 miles) from Oituz to Brețcu, this path slices through the eastern part of the country. Oituz Pass is the OG gateway to Transylvania, dating back to ancient times! Armies marched, traders hustled, and empires clashed right here. Think medieval ruins, monuments whispering stories of the past, and countryside that screams "postcard-worthy." Built way back in 1847, the route delivers some serious scenic charm. Keep your eyes peeled for quirky roadside vendors hawking fresh mushrooms. But remember, the history here is intense. This pass has seen some major battles, especially during World War I. So, while you're soaking in the views, remember the echoes of history surrounding you. It's a drive that's beautiful, thought-provoking, and definitely worth adding to your Romanian road trip itinerary!
extremeWhere is Lac du Vieux Emosson?
🇨🇭 Switzerland
Okay, picture this: you're in Switzerland, near the French border, and you're itching for an adventure. Forget the usual tourist traps and head to Lac du Vieux Emosson, a stunning high-altitude reservoir sitting pretty at a seriously impressive elevation. You'll find it nestled in the shadow of Mont Blanc. Now, getting there is half the fun. Starting from a mere spot, the paved road snakes upwards for a good little distance. Don't let the "paved" part fool you, though—it's narrow, steep, and has some heart-stopping drop-offs that will definitely keep you on your toes. For the first part of the journey, you'll find yourself winding through a couple of tunnels – classic Swiss engineering! Keep in mind this road is not accessible to private vehicles, but the views of the lower reservoir are insane! Plus, with breathtaking panoramas of Mont Blanc unfolding around every bend, it's a drive you won't soon forget. And if you're feeling peckish, there’s a restaurant near the dam. Open only in the summer months, this is one hidden gem you need to add to your Swiss road trip itinerary!
moderateDriving the paved road to Wurzen Pass in the Limestone Alps
🇦🇹 Austria
Wurzenpass-Korensko Sedlo sits pretty at 1,073 meters (3,520 feet) right on the Austrian-Slovenian border, connecting Carinthia with Slovenia's Upper Carniola region. This mountain pass has serious history—traders were already using it back in the 15th century, and the first proper road rolled through in 1734. Today, you'll find this fully paved route carved through the stunning Karawanks mountains in the Southern Limestone Alps. Known as B109 Wurzenpass Straße on the Austrian side and Slovenian highway No. 201 across the border, it's an 11.2-kilometer drive linking the Austrian town of Radendorf to the Slovenian village of Kranjska Gora (sitting on the Sava Dolinka River). Fair warning: this isn't your straightforward mountain drive. The road is seriously twisty with some intense grades hitting 18 percent—your brakes will definitely get a workout. Summer is peak season here since it's one of the most popular crossings between the two countries, so expect plenty of company on the pavement, especially in warm months. But if you're after gorgeous Alpine scenery mixed with a bit of driving challenge, this pass delivers.
