Okay, adventure-seekers, buckle up for the F337 (Hlöðuvallavegur) in Southern Iceland! This isn't your average Sunday drive. Nestled near Þingvellir National Park, this 28.9 km (17.95 miles) stretch is one of Iceland's steepest and most scenic.

Forget the pavement; this is pure, unadulterated Icelandic wilderness. Think lunar landscapes and a totally rough track that demands a 4x4 with serious ground clearance. Seriously, leave the family sedan at home. We're talking big stones, sandy patches, and a relentless climb. Get ready to ascend a whopping 500 vertical meters in just 4 km, hitting an average gradient of 15%!

You'll be soaring to 681m (2,234ft) above sea level, so get ready for those views! Keep in mind this road is typically closed from late October to late June/early July due to snow. This is a remote route; passing traffic is rare, and cell service can be spotty. Be prepared to be self-sufficient, and enjoy the raw, untamed beauty of Iceland!

Can you drive through Gorges de Galamus?extreme

Can you drive through Gorges de Galamus?

🇫🇷 France

Okay, picture this: the Gorges de Galamus, a canyon carved by the feisty Agly River right on the border of Aude and Pyrénées-Orientales in France. This isn't just any road; it's a balcony road, clinging to the cliffside like a daredevil. We're talking a 9.7 km (6.02 mile) stretch of pure driving adrenaline on the D7, connecting Cubières-sur-Cinoble to Saint-Paul-de-Fenouillet. It's paved, sure, but don't let that fool you. This road is NARROW. Like, squeeze-your-side-mirrors-in narrow. Think old-school charm meets modern-day driving challenge. You'll be winding along cliffs that plunge a cool 1,000 feet straight down. The views? Unreal! But fair warning: the driver might miss them because keeping your eyes on the road is a must. Heads up for summer travelers: July and August get crazy busy. They've got a system with traffic lights in the afternoons, so you might be chilling for 15 minutes waiting for your turn. Built way back in the 1890s by folks dangling from ropes (seriously!), this road demands respect. Be ready for anything – sudden winds, wandering pedestrians, and maybe even a few rafters heading for adventure. Small cars are best; leave your big SUV at home. But don't stress - there are regular passing places. Pro tip: Stop at the restaurant near Saint-Paul-de-Fenouillet for a jaw-dropping gorge viewpoint. And, 200 meters after the start of this amazing part of the D7 there is a hermitage that can be visited (no one is living there anymore) Make it a day trip by linking up with the D14 and D19 to visit the Chateau de Peyrepertuse and Château de Quéribus ruins and Grau de Maury, three amazing places to visit. The Gorges de Galamus? It's not just a drive; it's an experience!

Col de Saint Georges-Chalet Josserandhard

Col de Saint Georges-Chalet Josserand

🇫🇷 France

# Col de Saint Georges-Chalet Josserand Perched high in the French Alps at 2,245 meters (7,477 feet), this mountain pass in Hautes-Alpes is seriously not for the faint of heart—literally. The road to the summit is a rough gravel and rocky affair that'll test your nerves with its steep grades and bumpy sections that'll rattle your teeth. Fair warning: this isn't a summer-long destination. Weather usually keeps the road locked down from October through June, so you're looking at a pretty narrow window to tackle it. And when conditions permit, you'll need serious driving chops to handle it—experienced off-roaders only, please. No SUV? You'll need a 4x4 to make it happen. If unpaved mountain roads aren't your jam, do yourself a favor and skip this one. The elevation, the steepness, and the sheer exposure mean that vertigo sufferers should definitely steer clear. But if you've got the skills, the vehicle, and the guts, this Alpine adventure delivers a wild ride through some truly spectacular scenery.

Be prepared to drive the F910 road in the Highlands of Iceland

🇮🇸 Iceland

F910 (Austurleið) is a challenging mountain road located in the Northeastern Region of Iceland. It’s one of the famous F Roads of the country. The road is located in the northern part of the island, in the remote Highlands of Iceland. The road is quite challenging. It has paved sections but also very demanding parts. Most people only drive a small part of Austurleið – the section leading to Askja. However, F910 continues a long way through the central highlands. To drive on this road, you need a high clearance vehicle. It's only open in the summer for 4x4 vehicles. Snow and sandstorms might occur. Expect to be alone; this track is not very busy and is very remote. Travelers need to be well-prepared with enough food, water, and fuel for the drive ahead. This trail goes through complete wilderness without any services whatsoever; travelers have to bring all fuel and supplies. The road is 170 km (105 miles) long. It can be traversed with a decent 4WD vehicle, but it can be slow-going because parts of the road are bumpy. Some sections are extremely rough, especially where it passes over fields of solidified lava. Sand and snowstorms may cause serious problems, even in the summer, as well as several river crossings. It's recommended to travel together with other vehicles.Road suggested by: Glenn FantPic&video: Bas Brand Embark on a journey like never before!

The Unpaved Road to Monte Corrasi in Sardinia Runs Through a Lunar Landscapehard

The Unpaved Road to Monte Corrasi in Sardinia Runs Through a Lunar Landscape

🇮🇹 Italy

# Monte Corrasi: Sardinia's Wild Mountain Drive Buckle up for one of the Mediterranean's most thrilling and remote adventures! Monte Corrasi rises to 1,463m (4,799ft) on the rugged eastern coast of Sardinia, nestled within the stunning Parco Nazionale del Golfo di Orosei e del Gennargentu in Nuoro province. The Strada del Monte Corrasi is seriously not for the faint of heart. This completely unpaved, wickedly narrow road climbs relentlessly with 25 hairpin turns that'll keep your knuckles white the entire way up. You'll need a high-clearance vehicle—there's no way around it. The route follows old forest roads and occasionally cuts across the switchbacks, making for an intense 6.2 km (3.85 miles) push upward with a brutal 751m elevation gain and an average gradient of 12.11%. Starting from Strada Provinciale 22 (SP-22), the road is drivable all the way to a parking area near the summit, where private vehicles have to call it a day. And the payoff? Absolutely worth it. The summit looks like you've landed on another planet—high winds have stripped it bare, creating a lunar landscape scattered with karst formations, caves, gullies, and dramatic rock pinnacles in wild shapes. The views down into the valley below? Utterly breathtaking. This is a bucket-list drive for serious road-trippers who crave remote, raw adventure.
