# Col de Joux Plane: A Northern Alps Beast Worth the Suffering
If you're hunting for one of France's most legendary cycling climbs, Col de Joux Plane needs to be on your radar. Sitting at 1,697m (5,567ft) in Haute-Savoie, near the Swiss border, this pass shares elite company with the Galibier, Izoard, and Alpe d'Huez as one of the six major peaks that define the French Alps cycling scene.
The paved D354 connecting Morzine to the south and Samoëns to the north is deceptively short at 23.7 km (14.72 miles), but don't let that fool you—this road is a proper gut-check. From Morzine, you're looking at 10.9 km with 711m of elevation gain (6.5% average). From Samoëns? That's 11.6 km gaining 989m with a punishing 8.5% average. Some sections hit a brutal 15% gradient, and the road's narrow, often single-lane character makes it feel even more intense.
Here's the kicker: the entire slope faces south. If you're planning a summer attempt, seriously get an early start or you'll be cooking in the heat with nowhere to hide.
Reach the summit and you'll find Le Relais des Vallées bar and a parking area. Push a bit further on the gravel road north and you'll hit the true summit at 1,714m, where views of Mont-Blanc will make every painful pedal stroke worthwhile.
Tour de France directors love throwing this at cyclists for a reason—it's relentless from either direction, but the Samoëns side is genuinely one of Haute-Savoie's toughest climbs. While it might not have the star power of its southern cousins, Joux Plane absolutely belongs in the conversation of Northern Alps legends.

hardA delightful yet challenging drive to Forcella Chiandolada
🇮🇹 Italy
# Forcella Chiandolada Hidden in the scenic mid-Boite valley, Forcella Chiandolada (also called Forcella Ciandolada) sits at 1,582 meters (5,190 feet) and serves as a stunning gateway between two Dolomites giants—Antelao and Pelmo. Located in Belluno province in Veneto, it's about 68 miles north of Venice and just 30 kilometers from Belluno town. The 6.3-kilometer climb from Vodo di Cadore is no joke—expect an average gradient of 12%, with some sections pushing past 17%. The steepest pitches hit a brutal 25-26%, so bring your A-game. The road is mostly paved with stretches of gravel, but here's the thing: it gets *narrow*. Like, uncomfortably narrow for passing other vehicles. If you're not confident reversing a car, you might want to reconsider or time your visit carefully. Once you reach the top, you'll find Rifugio Giampietro Talamini waiting for you—recently rebuilt and perfect for catching your breath and refueling. It's the kind of reward that makes the white-knuckle drive absolutely worth it.
hardWhere is Lake Kapetan?
🌍 Montenegro
Lake Kapetanovo, nestled in Montenegro's Morača region, sits pretty high up there! You'll find this beauty in the western part of the country, tucked into the Moracke Planine mountains. Bonus: there are restaurants and mountain huts around the lake. So, what's the road like? Well, it's got a split personality! A 4x4 is highly recommended, but a high-clearance 2WD SUV can make it if you're careful and the weather is dry. There are two tricky climbs to watch out for — one steep, rocky climb right after the pavement ends, and another up the slopes of Lukavica, also loose and rocky. Things are changing fast, though! More and more of the road is being paved because Kapetanovo is getting super popular. It's *technically* possible to get there mostly on pavement and easy gravel if you know the secret routes, but most maps will send you on the off-road adventures. From Nikšić, the second-biggest city, it's quite a journey. The road starts paved and marked along the Gračanica River. Once you head towards Dragovoljci, things get narrow and steep — barely wide enough for one car, with switchbacks galore. Then, after a small village, the pavement vanishes! That first off-road bit has loose rocks, deep ruts, and some technical climbs. High clearance and 4WD are your friend here, but a careful 2WD SUV with good clearance might manage. A few miles later, the trail smooths out. You'll cruise through shaded forest with the occasional rut and tight bend, which might be a challenge if you’re driving something over 16 feet long. After about 10-15 minutes, the trees open up, revealing wide meadows, and the climb gets easier along Lukavica. Keep an eye out for hidden ruts in the grass and some steeper, rockier patches. On a clear day, you can even spot distant mountains! That scenic stretch takes about 20 minutes. Eventually, you'll hit pavement again, and it’s smooth sailing (mostly) to the lake. The road's narrow and a bit potholed, but it's in pretty good shape. The final push to Kapetanovo is fairly steep. Heavier vehicles might need to gear down for a bit. The last little bit is too narrow for passing, so watch for oncoming traffic. But trust me, once you conquer that final climb, you're rewarded with views of the gorgeous plateau and the turquoise waters of Kapetanovo Lake. It's a wild and beautiful place, totally worth the drive!
moderateMazalat
🌍 Bulgaria
Alright, thrill-seekers, buckle up for Mazalat, a heart-pumping peak experience in south-central Bulgaria's Stara Zagora province! Perched way up in the Stara Planina mountains at a cool 2,269 meters (7,444 feet), this isn't your average Sunday drive. The road? Think gravel, rocks, and a whole lotta shaking and bumping. You'll definitely want a 4x4 for this adventure! And heads up: being high up means you're at the mercy of Mother Nature. Expect strong winds, crazy-fast weather changes, and potentially even snow, even in summer! The cold here is no joke, especially in winter. But trust me, the views from the summit, ominously named Evil Peak, are SO worth it. Picture panoramic vistas of the Central Balkans stretching out in every direction. Seriously epic stuff!
moderateThe Road to Coll de Jou is a Chillout in the Pyrenees
🇪🇸 Spain
Coll de Jou is a high mountain pass sitting pretty at 1,637m (5,370ft) in the province of Girona, nestled in the heart of Catalonia's Pyrenees in northern Spain. At the summit, you'll find free parking and Refugi De Sant Jordi, a mountain shelter that's seen better days—it's unmaintained with two separate rooms, one featuring a fireplace that's more decorative than functional (it leaks!). The 14.7 km (9.13 miles) route runs west-east from Bruguera to Ogassa through the Serra Cavallera range, and it's a proper adventure. The road is fully paved with some concrete sections, but don't expect smooth sailing—this climb is steep and chunky, with a punishing 16.0% maximum gradient in places. The gradient keeps you guessing too, mixing steep ramps with gentler stretches throughout. Fair warning: it's narrow and twisty, so caravans need not apply. But here's the payoff: you're climbing through some seriously gorgeous mountain scenery in one of Europe's most stunning ranges. Just take your time, enjoy the views, and maybe skip the mountain refuge unless you're desperate for a chat with the fireplace.
