# Greppon Blanc: Alpine Adventure in the 4 Vallées
Ready for some serious alpine thrills? Greppon Blanc is calling—a stunning 2,635m (8,645ft) peak sitting pretty above the Veysonnaz and Thyon resorts in Switzerland's legendary 4 Vallées ski area.
The views alone are worth the drive. On a clear day, you're treated to jaw-dropping 360-degree panoramas of the Pennine Alps, with the iconic Matterhorn and Dent Blanche dominating the horizon. The landscape is raw and unfiltered—limestone rocks, sparse alpine vegetation, and that biting mountain wind that never seems to stop.
Here's where it gets real: the 5.3 km (3.29 miles) ascent from Thyon is no Sunday drive. You'll climb 529 meters with an average gradient of nearly 10%, but don't be fooled by "average"—the steepest sections hit a whopping 30%+. The surface is basically loose stones and rocky gravel that gets increasingly sketchy the higher you go. Seriously, bring a proper 4x4 with low-range gearing. Traction issues? Basically guaranteed.
This narrow maintenance track (originally built to service chairlifts) offers zero safety barriers and demands serious respect. You can only tackle it summer months—late June through September, weather permitting. Even then, mountain storms can roll in fast with snow and fog, catching you off guard.
Only experienced mountain drivers should attempt this one. If you know your way around high-altitude, loose terrain and aren't fazed by steep drop-offs and potential service traffic, Greppon Blanc delivers an unforgettable experience.

hardMarchlyn Mawr Dam Road: A Scenic Journey Through Wales' Heartland
🇬🇧 Wales
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!
hardPuerto de la Mata, an epic road in Andalusia
🇪🇸 Spain
Alright, adventure seekers, let's talk about Puerto de la Mata! This high-altitude gem sits pretty at 1,670m (5,479ft) in Andalusia, southern Spain's Almería province. Think serious climbs - we're talking up to 18% gradients. Tucked away in the Sierra Mágina Natural Park, the road to the top (also called Puerto Torres) is a rugged, unpaved treat that forms part of the GR-7 trail. It's usually open year-round, though winter weather can sometimes throw a curveball with temporary closures. The pass stretches for 20.1 km (12.48 miles), running north-south from the JA-3107 road (near Torres) to the A-324 road (near Mata Bejid), serving up incredible vistas as you go. Heads up - it *might* be closed during the summer fire season. This route is a steady climb, long but not too brutal. From Cambil, it's a 15.1 km ascent with an average gradient of 5.7% (spiking to 11.8% in spots!). Coming from Torres? Get ready for 12.3 km at an average of 6.7%, with some sections hitting that intense 18% mark. Get ready to shift gears and soak in the scenery!
hardPorlock Hill is the steepest A road in England
🇬🇧 England
Okay, buckle up, road trippers, because Porlock Hill in Somerset is a wild ride! They say it's the steepest A-road in England, and I believe it. Just west of Porlock village, this paved beauty (and I use the term loosely!) is only about 2 miles long but packs a serious punch. We're talking super narrow sections, two crazy-tight 180-degree hairpin turns, and gradients that'll make your palms sweat. This stretch of the A39 connects Porlock to Lynmouth and climbs a whopping 1,300 feet onto Exmoor. Definitely not for caravans or big rigs – seriously, find another route. Cyclists, you might want to walk this one! It's a leg-breaker for sure, with that final stretch averaging 8% and hitting 25% in spots! You can practically smell burning brakes in Porlock from cars coming down. They've even got two escape lanes for runaway vehicles – yeah, it's that intense. Apparently, there have been plenty of accidents here. This crazy road opened back in 1843. If you're not feeling adventurous, there's a toll road alternative – smart move for caravans. Small cars and cyclists can find another way around too. But hey, if you're looking for a challenge and some incredible views, Porlock Hill is an unforgettable experience!
hardLabasar Refuge
🇪🇸 Spain
# Refugio de Labasar Nestled in the heart of Spain's Sobrarbe region in Huesca, Aragon, this mountain refuge sits pretty at 1,949m (6,394ft) above sea level, right in the Pyrenees. The drive up to get here? Yeah, it's an adventure. You're looking at a gravel and rocky road that can be tippy and bumpy—definitely not your typical smooth highway experience. Winter basically shuts this place down, so plan your visit for warmer months. If you've got some serious off-roading experience under your belt, you'll probably dig it. Here's the good news: the road is maintained, and a high-clearance 2WD vehicle can handle it just fine if you take it slow and steady on the dry stretches. The not-so-good news? Prepare yourself for some seriously steep climbing. And if you hit wet weather, all that mud turns this into a proper challenge. Washboarding, ruts, and dips are real here, so white-knuckling through them is part of the deal. Bottom line: this is one for drivers who know what they're doing and don't mind a little (okay, a lot) of bumping around to reach an incredible mountain destination.
