Year-round
Nestled high in the Spanish Pyrenees, in Catalonia's wild northwest corner, you'll find the Tunel de Vielha. This isn't just any tunnel, though. We're talking about a 5.2km (3.25 mile) stretch of paved road boring through the mountains, connecting Vielha, the Aran Valley's main hub, with the Alta Ribagorça region.
A bit of history: Before this tunnel, the Aran Valley was pretty cut off, especially in winter. The original tunnel, once the world's longest, got a bit dicey safety-wise, so the updated Juan Carlos I Tunnel was opened in 2007.
The road itself? It's part of the N230, with two lanes heading south and one going north, so be aware of the traffic flow! Expect some steep climbs inside, with gradients hitting up to 7.5% in places. The elevation peaks at 1,635m (5,364ft) above sea level.
You can usually cruise through year-round, but keep an eye on the weather – it might close briefly in heavy winter storms. If you're coming from Vielha, it's a 12.3 km climb, gaining 664 meters in elevation (averaging 5.4%). Coming from Villaler, it’s a longer, gentler 18.7 km climb with an elevation gain of 656 meters (averaging 3.5%). Prepare for some beautiful mountain scenery!

moderateOuvrage La Déa
🇫🇷 France
Okay, so you're looking for an off-the-beaten-path adventure in France? Check out the road to Ouvrage La Déa, a seriously cool military fortress clinging to the mountains in Alpes-Maritimes! Perched way up high at 1,753 meters (that's 5,751 feet!), getting there is half the fun. Be warned: this isn't your typical smooth cruise. Expect a gravel and rocky track that can get a little tippy and bumpy in places. It's a mountain road, so yeah, there are some major drop-offs to keep you on your toes! Usually, snow makes it impassable from October to June, so plan accordingly. Not a fan of heights or unpaved roads? This one might not be for you. But if you're up for a challenge and love incredible views, the fortress (also called Petit Ouvrage de la baisse de la Déa, built back in 1934!) is totally worth the trek!
extremeA curvy scenic road to Col de la Couillole
🇫🇷 France
# Col de la Couillole Nestled in the Alpes-Maritimes region of southeastern France, Col de la Couillole sits at a whopping 1,678m elevation and serves as part of the legendary Route des Grandes Alpes. This fully paved route (D30, which becomes M30 after the pass) stretches 23.4km from Beuil to Saint-Sauveur-sur-Tinée and winds through the stunning Mercantour National Park. Fair warning: this road is seriously steep and curvy. You'll encounter hairpin turns, narrow sections, and charming tunnels that make for an exhilarating—but gorgeous—drive. The scenery? Absolutely breathtaking at every turn. Cyclists know this pass well; the Tour de France has tackled it multiple times. Starting from Saint-Sauveur-sur-Tinée at just 504m elevation, riders face 15.7km of climbing with 1,174 meters of elevation gain. The average gradient of 7.5% sounds reasonable until you realize there's barely a flat section below 6%, with several stretches hitting 8% and peaks reaching 11%. It's relentless in the best way possible. While you're in the area, don't miss the picturesque village of Roubion, perched near the road. It's truly a hidden gem—literally at the end of the road—with local hotels and stunning views. Fair note: if you're coming from the Beuil side, you won't see signs for it, so keep your eyes peeled.
moderateWhere is Kronplatz-Plan de Corones?
🇮🇹 Italy
Okay, so Kronplatz-Plan de Corones is this crazy-high mountain pass in the stunning Italian Alps of South Tyrol. You'll find it nestled right in the autonomous region of Trentino-Alto Adige/Südtirol. The road up? Well, it's paved but in two distinct acts. First, you're cruising up from Furkelpass - Passo Furcia. It starts off easy, lulling you into a false sense of security before throwing some serious steepness your way towards the end of the asphalt. Then comes the real challenge. Picture tons of hairpin bends, each one seemingly steeper than the last. We're talking max gradients of 21-24%! This climb has even tested the legs of pros in the Giro d'Italia bicycle race. If you're tackling it from St. Vigil in Enneberg, it's about long with serious elevation gain.
hardRoad trip guide: Conquering Śnieżne Kotły
🌍 Poland
Okay, adventure junkies, buckle up for Śnieżne Kotły, also known as the Snowy Pits! This peak straddling the Polish-Czech border punches way up to 1,486 meters (that’s nearly 4,900 feet!). You'll find this wild ride nestled in the Sudetes mountains, right in the heart of the Krkonoše National Park. Be warned: the road up is a gravelly beast riddled with potholes. A 4x4 isn’t just recommended, it's practically mandatory. Keep a weather eye out. Seriously, conditions can shift on a dime. Expect road closures, especially since fog and clouds seem to love hanging out up here for most of the year. Winter? Forget about it. This track is a total no-go, and snow often sticks around well into April. Think tough conditions, and avoid this road like the plague in the wet or dark. Oh, and did I mention you're dealing with altitude and the potential for seriously crazy weather, no matter what time of year? At the top, look for the radio television mast. Happy trails!
