# Col du Glandon: A Alpine Classic Worth the Climb
Nestled high in the Dauphiné Alps at 1,930m (6,332ft), Col du Glandon is one seriously impressive mountain pass that'll test even experienced drivers. Located in the Savoie department of southeastern France, this beauty stretches a whopping 46.4 km (28.83 miles) between Barrage du Verney and La Chambre, and it's fully paved on road D927.
Here's the deal: this pass has serious credentials. Built way back in 1898, it first appeared in the Tour de France in 1947 and has been a favorite challenge ever since. Every July, it kicks off La Marmotte sportive as the first climb, and summer brings decent traffic as riders and drivers flock here for the stunning views.
The climb is no joke though. Those last seven kilometers? They're where things get real, with gradients ramping up to a brutal 15.5% max. The final two kilometers are relentless—mostly over 10% with stretches hitting 12%. Coming from Barrage du Verney, you're looking at 24.12 km gaining 1,152m (average 4.8%), while the La Chambre approach is 21.3 km with 1,472m elevation gain (average 6.9%).
At the summit, you'll find a proper parking area and a bar-restaurant where you can catch your breath and soak in those incredible alpine views. Fair warning though: the road typically closes from early November through mid-May, so plan your visit for the warmer months.

moderateZekari Pass: Ultimate 4wd destination
🇬🇪 Georgia
Alright, adventure junkies, buckle up for Zekari Pass in Georgia! This wild ride straddles the Imereti and Samtskhe-Javakheti regions, hitting a lofty 7,076 feet above sea level. Forget smooth asphalt – this is a 24.35-mile rollercoaster of a dirt track winding from Sairme in the north to Abastumani, the old Soviet sanatorium area, down south. We're talking SH14, folks! Seriously, you'll want a proper off-road vehicle for this one. The road is rough, like REALLY rough, and heavy rain can turn it into a mud bath. Allow 2-3 hours to crawl your way through. Keep an eye out for the Georgian Academy of Sciences observatory near the pass, a relic from the USSR days. You can even hitch a ride up via cable car (hit them up to register first). Expect shepherd camps dotting the landscape as you weave through the Meskheti Range. Word to the wise: this route is usually snowed in from October to June, weather depending. But when it's open? Prepare for some amazing mountain vistas and seriously epic off-roading. The highest point is actually *north* of the pass itself, peaking at 7,463ft.
extremeA brutally steep road to Alto del Gamoniteiro
🇪🇸 Spain
# Alto del Gamoniteiro: Asturias' Brutal Mountain Gem Tucked away in the Sierra del Aramo mountain range in northern Spain, Alto del Gamoniteiro sits at a whopping 1,776m (5,826ft) and claims the title of Asturias' highest paved road. If you're planning a visit, prepare yourself for one seriously epic ride. This isn't your average scenic drive. The 6.4 km (3.97 miles) climb from AS-230 packs 625 meters of elevation gain into its narrow, winding route—and it doesn't hold back. With an average grade of 9.76%, this road gets downright vicious in places, hitting a brutal 17% through the steepest sections. The final 1.5 km? Relentless suffering, averaging 12% with virtually no mercy. Fair warning: the road surface is sketch. We're talking crumbly asphalt, concrete patches, potholes, and hairpin turns that'll test your nerves. And if heights make you queasy, maybe don't look too far over the edge—the views are stunning, but they're also *very* long down. The climb is broken into three progressively harder sections, with that nail-biting final kilometer averaging 13.3%. Some call it Spain's answer to Mont Ventoux, minus the tourist hordes. At the summit, you'll find a small parking lot and communication towers—plus access to a short 2 km unpaved road leading to Lago de Cueva, a gorgeous high-altitude lagoon with 11 hairpin turns of its own. This is genuinely one of the most beautiful climbs in the region. Just bring your legs, your determination, and your sense of adventure.
hardRoad trip guide: Conquering Mannlichen in the Swiss Alps
🇨🇭 Switzerland
# Männlichen: A Swiss Alpine Adventure Perched at 2,343 meters (7,687 feet) in the heart of the Jungfrau region, Männlichen is one of those bucket-list drives that'll have you questioning your life choices—in the best way possible. Located in Switzerland's Canton of Berne, this mountain peak sits smack in the middle of the spectacular Bernese Alps. Here's the thing: the road to the top is completely unpaved, and it's not for the faint of heart. You'll need a serious 4x4 to handle the relentless steepness—we're talking maximum gradients that hit 16% on some stretches. The route, dubbed the Männlichen Royal Walk, is a 750-meter push uphill from Berghaus Männlichen, climbing 81 meters with an average grade of 10.8%. And fair warning: it's a dead-end, so whatever you drive up, you're driving back down the same way. But here's why it's worth every white-knuckle moment: the views are absolutely unreal. On a clear day, the panorama across the Alps will leave you speechless. As you wind through the Bernese Oberland on your approach, the Jungfrau massif looms larger with every turn, and you'll understand why this region is legendary. One heads-up: private motorized vehicles aren't allowed, so you'll need to arrange appropriate transport. But whether it's summer wildflowers or winter wonderland, a trip to Männlichen offers those rare moments where you're genuinely connected to the raw beauty of nature.
hardFort de Pattacreuse
🇫🇷 France
# Fort de Pattacreuse: A High-Alpine Adventure Tucked away in the Savoie department of southeastern France's Rhône-Alpes region sits Fort de Pattacreuse, perched dramatically at 2,385 meters (7,824 feet) above sea level. This isn't your typical Sunday drive—it's a genuine mountain expedition. The path to this fortress is pure gravel, a rugged route that's been around since 1891. Along the way, you'll spot fascinating military structures dotting the landscape, remnants of the area's strategic past. Fair warning though: this road is only passable from July through August. Come winter (or basically any other season), Mother Nature closes the door—erosion and snow make it completely impassable from September through June. Even during the brief summer window when you can actually drive it, expect a genuinely bumpy, washed-out experience. The decades haven't been kind to this mountain road, and it shows in every pothole and ridge. It's the kind of drive that tests both your vehicle and your patience, but rewards you with some seriously stunning high-altitude scenery and the thrill of reaching a genuine fortress in the clouds.
