# Alto de Aitana: Spain's Hidden Mountain Challenge
Nestled in the sun-soaked province of Alicante, Alto de Aitana stands tall at 1,543 meters (5,062 feet) and claims the crown as the province's highest peak. Located in the southern reaches of Spain's Valencian Community, this mountain fortress has serious credentials—it's home to a Spanish military installation complete with communication towers, a radar dome, and TV antennas perched at the summit.
Here's the catch: the road is strictly off-limits to regular visitors. A barrier at the base makes it crystal clear that only authorized military personnel can drive up this mountain road.
But here's what makes it legendary among cycling enthusiasts: the climb itself is absolutely brutal in the best way possible. Starting from Port de Tudons, you're looking at 6.5 kilometers (4 miles) of relentless uphill action, gaining 516 meters of elevation along the way. The entire route is paved, which is nice, but don't let that fool you—sections hit a punishing 14.6% gradient that'll test your legs and your lungs. With an average grade of nearly 8%, this isn't a leisurely Sunday ride.
The road has earned its stripes as a stage in Spain's prestigious Vuelta race, proving this climb belongs among Europe's most challenging mountain passes. If you could drive it, the spectacular scenery amid the Sierra Aitana range would make every hairpin turn worthwhile.

extremeHow to drive the narrow Road B885 at the centre of the Isle of Skye?
🇬🇧 Scotland
Okay, buckle up, adventure seekers! The B885 on the Isle of Skye is calling your name! This isn't your average Sunday drive, though. We're talking a proper, nail-biting, single-track road that carves right through the heart of the island, from Bracadale on the west coast to Portree, the island's bustling capital. Stretching for just over 9 miles, this ribbon of tarmac winds its way through unbelievably narrow glens draped in forests. Picture this: sections so tight that two cars can absolutely NOT pass at the same time. Seriously, your reversing skills will be put to the ultimate test! But if you're up for the challenge, the views are simply breathtaking! Just take your time, use those passing places wisely, and get ready for an unforgettable Skye adventure.
moderateDriving through Vielha Tunnel in Spain's Pyrenees
🇪🇸 Spain
# Tunel de Vielha Nestled high in the Pyrenees at 1,635m (5,364ft), the Tunel de Vielha sits in Catalonia's northwestern corner in the Province of Lleida. This tunnel has quite the backstory—the Aran valley used to be seriously cut off from the rest of Spain, especially when winter snow decided to block access for weeks on end. Back in 1948, they built the Alfonso XIII Tunnel, a real engineering feat at 5.24km long—the world's longest road tunnel at the time. Fast forward to 2000, and it had earned a pretty dark reputation as Europe's most dangerous tunnel due to outdated safety features. That's why they opened the newer Juan Carlos I Tunnel in 2007. These days, the old tunnel mainly serves as a backup route for hazardous cargo trucks. Today's version connects Vielha (the valley's main hub) to the Alta Ribagorça area via the N230. The fully paved route stretches 5.2km (3.25 miles) with two southbound lanes and one northbound lane, with grades that climb up to 7.5%. You can generally drive it year-round, though expect occasional closures during gnarly winter weather. Want to tackle the approaches? From Vielha, it's a 12.3km climb gaining 664 meters (averaging 5.4%). Coming from Villaler? That's a slightly easier 18.7km push with 656 meters of elevation gain at a gentler 3.5% average gradient. Either way, you're in for some serious mountain scenery.
hardCol du Clergeon
🇫🇷 France
Okay, buckle up for Col du Clergeon, a killer mountain pass nestled in the French Jura Mountains! This one tops out at 979m (3,211ft) and the climb is a full 10km of pure adrenaline. We're talking asphalt (D55, if you're mapping it), but don't let that fool you - those middle two kilometers are BRUTAL, averaging a leg-burning 10.5% grade with some sections way steeper. Plus, it's narrow! And keep an eye on the weather, because snow can shut this beauty down in a heartbeat. But hey, all that effort is worth it for the views! You’re looking at a 7.3% average incline over the whole climb – a true test for you and your car.
hardAdventure along the wild road to Starkenburger Hütte in the Stubai Alps
🇦🇹 Austria
# Starkenburger Hütte: A Wild Alpine Adventure Tucked away in Austria's Stubai Alps at a breathtaking 2,237m (7,339ft), the Starkenburger Hütte is a serious mountain destination that'll test your driving skills. This historic refuge—built way back in 1900 by the German Alpine Club—sits high above the charming village of Neustift in Tyrol, and reaching it is half the adventure. The 12.6km (7.82 miles) journey from Neustift im Stubaital is no joke. You're climbing 1,225m with an average gradient of 9.72%, and the road is unpaved, narrow, and seriously steep. Fair warning: it's rough going in winter and turns sketchy after rain, so timing your visit is crucial. Also, private vehicles aren't allowed—you'll need to plan accordingly. Here's the good news though: the rewards are absolutely worth it. The views? Spectacular. You're surrounded by the stunning Stubai mountains with their jaw-dropping collection of 3,000-meter peaks stretching out in every direction. The hut itself only opens from early June through mid-October depending on conditions, and you'll want to keep tabs on avalanche forecasts before heading up. This isn't a casual Sunday drive—it's a serious alpine expedition for adventurous road-trippers ready for a real challenge.
