Year-round
Okay, picture this: You're in Wales, exploring Snowdonia's stunning mountains, and you stumble upon this crazy little road leading up to Marchlyn Mawr Dam. This ain't your average Sunday drive, folks!
We're talking about a completely paved but seriously narrow ribbon of tarmac that climbs up to 643m (2,109ft) above sea level. It's one of the highest roads you'll find in Wales! Built back in the late '70s, this 5.31km (3.3 miles) climb from Deiniolen is no joke. It's got some seriously steep sections, with gradients hitting a whopping 12.6% in places – your legs will definitely feel it if you're cycling!
Starting at the foot of Elidir Fawr, you gain a massive 426 meters in elevation, averaging around 8%, as you wind your way up. Heads up, though: this road is owned by the local power company, and while cyclists are welcome to grind their gears all the way up, a gate keeps cars from reaching the top, with the final 2.89km (1.8 miles) being off-limits to private vehicles. But honestly, the views are worth the effort. Just plan ahead!

hardPresolana Pass
🇮🇹 Italy
# Passo della Presolana Tucked away in Bergamo Province in Italy's Lombardy region, Passo della Presolana sits at a cool 1,297 meters (4,255 feet) above sea level—and it's absolutely worth the drive to get there. The road up is fully paved (SPexSS671), but don't let that fool you into thinking it's a leisurely cruise. This route is serious business, with tight hairpin bends that'll keep you on your toes and grades that hit 14% in some sections. It's the kind of climb that'll get your adrenaline pumping—and your car working hard. You've got two main starting points, depending on your preference. Coming from Dezzo di Scalve, you're looking at a shorter but spicier 7.95 km push with 548 meters of elevation gain (averaging 6.9%). Prefer a gentler pace? Start from Rovetta instead, and you'll tackle 11.95 km with 651 meters of gain averaging 5.4%—still challenging, but a bit more forgiving. This pass has earned some serious street cred too—the legendary Giro d'Italia race has tested cyclists on these very roads, so you know you're on something special.
hardYork’s Hill is one of the steepest roads of England
🇬🇧 England
Okay, cycling fans, listen up! You HAVE to check out York’s Hill in Kent, England. Seriously, it's legendary! This isn't just any climb; it’s a ridiculously steep, winding ribbon of pavement that'll test your legs and lungs like never before. The road? Let’s just say it’s… intimate. Picture this: a super narrow, paved surface barely wide enough for you and your trusty bike. Forget cars; this is strictly two-wheeled territory. Starting at 120m and topping out at 202m, this 0.64km stretch packs a serious punch, boasting an average gradient of 13%. But hold on tight, because right at the end, BAM! You’re staring down a brutal 20-25% gradient that'll have you questioning all your life choices. Oh, and did I mention this hill is steeped in cycling history? It's hosted the Catford hill climb, the world’s oldest bike race, since way back in 1887. Talk about a challenging climb with a view and a serious dose of cycling heritage!
extremePeñón de Vélez de la Gomera road: Driving to the world’s shortest border
🇪🇸 Spain
# Peñón de Vélez de la Gomera: Where Spain Clings to Morocco Peñón de Vélez de la Gomera is a wild geopolitical oddity tucked on Morocco's northern coast. Here's the crazy part: this Spanish enclave used to be a legit island until a monster storm in 1934 dumped enough sand to create a land bridge. Now? You've got the world's shortest international border—just 85 meters of sandy isthmus separating Spanish territory from Morocco. It's the kind of thing that makes you wonder what the mapmakers were thinking. Getting there is where things get properly adventurous. You'll be threading through the dramatic Rif mountains on the Moroccan side via a rough dirt track that's definitely not anyone's idea of a leisurely Sunday drive. Heading out from Torres de Alcalá, this 5.8 km route is narrow, unpaved, and gloriously unforgiving. Expect steep climbs, hairpin turns, and some seriously exposed sections with jaw-dropping drops toward the Mediterranean below. The road is basically loose gravel and dust—think more "lunar landscape" than "scenic byway"—and wet season? Forget about it unless you're driving something with serious clearance. A 4x4 is basically mandatory here. Here's the critical bit: this rock is serious business. It's a active military zone run by Spain, and civilians absolutely cannot cross that border. The road ends at a high-altitude lookout point, which is actually perfect because the views are mind-blowing. From up there, you're staring down at a legitimate Spanish fortress literally anchored to Morocco by a beach, with the sparkling Med spreading out in every direction. The real magic is in the sheer remoteness and the bizarre geography of it all. You're driving through some of the Mediterranean's most breathtaking coastal terrain, and the whole experience feels like you've found the edge of the world. It's the ultimate combo: gnarly driving meets fascinating geopolitical history. Absolutely worth the adventure.
moderateWhere is Superbagnères?
🇫🇷 France
Okay, picture this: You're in the French Pyrenees, ready for an epic climb up to Superbagnères ski station. This isn't just any drive; it's a fully paved adventure on the D46, starting from Bagnères de Luchon. The road is in great shape, but be warned, there are some seriously steep sections – over 12.5% in places that’ll test your mettle! The whole climb stretches for 18.5 kilometers (almost 11.5 miles), and you'll gain a whopping 1,170 meters in elevation. That’s an average gradient of 6.3%, so get ready to work those gears. This road has even seen Tour de France finishes, though a bridge weight limit means it's off the route for now! But trust me, the views are worth every hairpin turn! Winding around the mountain, you get these incredible, ever-changing vistas. And the payoff at the top? A full 360-degree panorama surrounded by fifteen snow-capped peaks towering over 3,000 meters. On a clear day, it's absolutely breathtaking. This road really snakes its way up and up, promising amazing views. You absolutely have to experience it!
