# Chluse Gorge: Switzerland's Most Dramatic Mountain Drive
Tucked away in the southwestern Swiss Alps, Chluse Gorge is a bucket-list worthy canyon that's been drawing adventurers since ancient times. This narrow passageway serves as the gateway to the stunning Gasterntal Valley—a UNESCO-protected nature reserve that's absolutely breathtaking.
Here's where it gets interesting: the road is *so* narrow that traffic is strictly one-way in alternating directions. You get 20 minutes to head down, then the flow reverses for 20 minutes going up. It's a clever system, but it definitely adds to the adrenaline rush!
The 11.4 km (7.08 miles) route stretches from Gasterntal to Kandersteg, mostly unpaved and carved directly into the mountainside. You'll wind past the churning River Kander, navigating around dramatic arched bridges, tunnels, and carved galleries—all original 19th and early 20th-century engineering marvels that somehow still look incredible today. The first proper road was completed in 1912, and remarkably, it's barely changed in over a century.
Fair warning: this isn't a scenic cruise you can take your time with. The drive typically takes 30-45 minutes of focused, careful navigation. With sheer rock walls towering above and the mountain carved away beneath your tires, you'll definitely feel that pressure behind the wheel.
The gorge is typically open from mid-May through mid-October, depending on snow conditions. It's intense, it's historic, and it's absolutely unforgettable.

hardA very narrow road to Chew Reservoir in Greater Manchester
🇬🇧 England
Okay, adventure awaits in Greater Manchester! Let's talk about Chew Reservoir. Perched way up high at 1,600 feet, this beauty was England's highest reservoir for ages. You'll find it nestled at the top of Chew Valley. The road? Mostly paved, but keep an eye out for a bit of gravel thrown in for good measure. It's known as Chew Road, but here's the thing: private cars aren't allowed all the way up. Park up near Dovestone Reservoir and enjoy the final leg on foot. Trust me, the views of Saddleworth Moor are worth it! This climb, starting from the A635 near Greenfield, clocks in at just under 3 miles, but don't let the short distance fool you. You'll gain over 900 feet, making for a pretty solid 6% average gradient. Get ready for those legs to feel it!
hardWhere is Wurzen Pass?
🇦🇹 Austria
Wurzenpass-Korensko Sedlo: high five to this epic mountain pass straddling Austria and Slovenia! You'll find yourself cruising at a cool 1,073m (3,520ft) above sea level, right on the border between Carinthia (Austria) and the Upper Carniola region (Slovenia). This route has been a go-to since way back in the 15th century, with a proper road carved out in 1734. Winding through the Karawanks, part of the Southern Limestone Alps, the B109 Wurzenpass Straße (in Austria) and Slovenian highway No. 201 (in Slovenia) is fully paved. Hold on tight though, this 11.2 km stretch from Radendorf (Austria) to Kranjska Gora (Slovenia) is a rollercoaster of curves and steep climbs, with gradients hitting a max of 18%! And because it's a popular border crossing, especially during summer, expect some company along the way. The views? Totally worth it.
hardCol du Tronc
🇨🇭 Switzerland
# Col du Tronc: A High-Alpine Adventure in Valais Nestled in the Martigny district of Switzerland's Valais canton, Col du Tronc sits at a dramatic 1,612 meters (5,288 feet) above sea level. This pass—also called Col des Planches—is pure alpine adventure. Fair warning: this isn't your typical highway. The route to the summit is mostly gravel, narrow, and seriously steep. It's only open to vehicles under 18 tons, so don't even think about bringing that RV. Winter is when things get really tricky. The high altitude means heavy snowfall is practically guaranteed, and the road can shut down at a moment's notice when conditions aren't safe to navigate. If you're after that raw, authentic mountain experience with zero pretense, this wild unpaved road delivers. Just check conditions before you go—timing is everything up here.
moderateColle di Perascritta
🇮🇹 Italy
# Colle di Perascritta Ready for an alpine adventure? Colle di Perascritta sits pretty at 2,154 meters (7,066 feet) in Piedmont, Italy, and it's absolutely worth the journey. The route up—officially called Strada del Lago di Monastero, or Alpe Costapiana if you're feeling local—is a gravel road that doesn't pull any punches. Expect steep grades and surfaces that get sketchy when wet, so timing your visit for dry conditions is pretty important. Winter? Forget about it—this pass is completely inaccessible once the snow rolls in. But here's what makes the effort worthwhile: as you climb, you'll discover the stunning Lago di Monastero, a serene mountain lake near the summit that's the perfect reward for tackling those gnarly switchbacks. The scenery is legitimately gorgeous, with that classic high-alpine landscape that'll have you reaching for your camera constantly. What adds another layer of character to this drive is the presence of several war memorials scattered along the route—quiet reminders of the region's complex history. So grab a full tank of gas, check your tire tread, and head out on a clear day. This is the kind of road trip that sticks with you.
