# Schlüsseljoch: A Bucket-List Alpine Challenge
Perched at 2,212m (7,257ft) in the stunning Zillertal Alps, Schlüsseljoch is one of those legendary passes that separates the adventurous from the faint-hearted. Known locally as Col della Chiave or Passo della Chiave, this mountain gateway sits right on the border between Italy's South Tyrol and Austria, bridging the Val di Vizze to the west with the Valle Isarco to the east.
Here's where it gets interesting: the entire 14.1 km (8.76 miles) route is unpaved. This old military track, built with strategic purposes in mind, isn't your typical smooth mountain pass. We're talking narrow, rough, seriously damaged surfaces with steep sections and teeth-rattling hairpin turns. If you're bringing wheels, you'll absolutely need a high-clearance 4x4—and even then, you might want to reconsider.
The drive starts near the village of Borgone on the SP508 Road and finishes at the SS12 near Terme di Brennero. It's slow going, demanding every ounce of your vehicle's (and your) capability.
**Fair warning though:** many high mountain tracks in South Tyrol are now off-limits to regular vehicles. Before you pack the car, check local regulations around the Sterzing/Vipiteno area first. If it's closed to cars, don't worry—the Schlüsseljoch has become a legendary (and brutal) playground for mountain bikers and hikers.
Also worth knowing: this pass gets buried under snow from late October through June, and there's zero winter maintenance. Winter driving? Not happening.

hardBull Bridge is an old wooden bridge on Ireland's east coast
🌍 Ireland
Okay, picture this: You're cruising along Ireland's stunning east coast, just outside of Dublin, and BAM! You spot it – the Bull Bridge, also known as the Wooden Bridge. This isn't your average crossing; it's a seriously charming, old-school wooden structure linking Dublin to the wild beauty of North Bull Island in Dublin Bay. Built way back in 1821, this narrow bridge has a two-ton weight limit, so leave the monster truck at home. Originally, it was just a temporary structure to help build the Bull Wall. Can you imagine? Lucky for us, the locals loved it so much for their beach trips and seaside picnics that they fought to keep it around. Trust me, you'll be glad they did! The views are incredible, and it's a totally unique experience driving across this historic gem.
extremeWhere is the D219 road?
🇫🇷 France
Okay, thrill-seekers, buckle up for the D219! This 9km stretch of pure adrenaline is carved into the French Alps east of Grenoble, near epic spots like Alpe d'Huez and Les Deux Alpes. Think balcony road, but amped up! This baby's paved, but don't let that fool you. We're talking super narrow sections hugging the side of a cliff above the Romanche River, so if you're afraid of heights, maybe grab a postcard instead. Oh, and did I mention the 9 hairpin turns and 4 unlit tunnels? Yeah, bring a flashlight (and maybe a change of underwear). You can drive it year-round, weather permitting, but snow can shut it down in winter. And leave your RV at home – it's only open to vehicles under 15 tons, 7 meters long, and 3 meters wide. But the views? Absolutely breathtaking. Towering mountains, sheer drops, and that feeling of being right on the edge. Just a tiny stone wall separates you from the void, making for some seriously stunning photos. After emerging from the tunnels, the views just keep on getting better! This road is a must-drive for anyone craving an unforgettable alpine experience!
hardMittelbergpass, an awe-inspiring lonely road
🇨🇭 Switzerland
# Mittelberg Pass: Switzerland's Scenic Alpine Challenge Ready for some seriously fun mountain driving? Mittelberg Pass sits pretty at 1,633 meters (5,357 feet) in the Swiss canton of Bern, and it's absolutely worth the detour. Starting from Saanen, you've got a 10.6 km climb ahead that'll gain you 619 meters of elevation. The road is paved—thank goodness—but don't let that fool you. This route is legitimately twisty, with hairpin turns that'll keep your hands busy and a jaw-dropping 14.3% gradient on the steepest sections. The average gradient sits around 5.8%, so you're in for a solid alpine workout. The full pass stretches 19.7 km from north to south, connecting the charming village of Jaun in Fribourg canton to Saanen in Bern. It's one of those routes that combines technical driving with absolutely stunning mountain scenery—the kind of road that makes you understand why the Swiss Alps are legendary. If you're hunting for an adrenaline-pumping mountain drive with epic views, this is it. Just make sure your brakes are in top shape and you're ready for some serious curves!
hardGorges de Daluis is a balcony road in France
🇫🇷 France
# Gorges de Daluis: France's Thrilling Canyon Drive Ready for an adrenaline-pumping Alpine adventure? The Gorges de Daluis, tucked away in the Alpes-Maritimes department of southeastern France, is absolutely not your average scenic drive. This stunning canyon carves through the upper Var River in the Provence-Alpes-Côte d'Azur region, and locals have dubbed it the "Little Colorado of Nice" for good reason. The 11.2-kilometer D2202 road snakes through the six-kilometer-long gorge from Guillaumes to Daluis, and it's a wild ride. You'll navigate 17 unlit tunnels and cross the breathtaking Pont de la Mariée, a stunning quartzite bridge that's become iconic in its own right. The road's nickname? The Chocolate Canyon—and once you see the dramatic russet-colored cliffs towering above you, you'll understand why. Things get seriously intense as you venture deeper into the gorge. The route twists relentlessly through narrow rock cuttings and impossibly tight tunnels, hugging the precipice as it follows the river below. If heights make your palms sweat, fair warning: some sections literally hang out over the drop. The upside? Other sections cleverly tunnel through the rock face for a different kind of thrill. Most drivers tackle the route in 15-25 minutes, but honestly, you might want to linger. Winter's the best time to visit—when snowmelt transforms the Var River into a raging torrent that amplifies the whole dramatic experience. This is a bucket-list road that's part of the famous Route des Grandes Alpes, and it's fully paved, so you can focus on soaking in the spectacular landscape rather than worrying about road conditions.
