Year-round
Cruising through the Serra da Estrela Natural Park in northeastern Portugal? You absolutely HAVE to tackle Regional Road 339 (R 339) up to Alto de Torre! This paved beauty winds for 50 km (31 miles) from Seia to CovilhĂŁ, ultimately delivering you to the highest point in Mainland Portugal at a cool 1,996m (6,548ft).
Fair warning, this isn't a Sunday drive for the faint of heart! Prepare for some seriously steep climbs; you'll be hitting gradients of up to 10.4% in places! The summit itself is a bit of a scene, with radar domes, a chapel, and even spots to grab a bite.
Usually, you can reach the top year-round, but be aware that winter can throw a wrench in the plans with closures due to crazy weather. In fact, this peak sees the lowest temps in all of Portugal! If you're lucky enough to be there during a cold snap, it's the only spot in the country where you can ski.
Oh, and the views? Forget about it! King John the 6th knew what he was doing when he ordered that stone monument ("Torre" - Tower) to be built up there. On a clear day, you can supposedly see the Atlantic Ocean way off in the distance - over 100 miles (161 km)! Seriously, this drive is worth every hairpin turn.

hardWhere is Tanarello Pass?
🇫🇷 France
Okay, buckle up, adventure seekers! Let's talk Tanarello Pass, perched way up high on the French-Italian border. We're talking serious altitude here! This isn't your Sunday drive. It's a Ligurian track, a relic from a time when salt was king, connecting Ventimiglia to Limone Piemonte. Now, picture this: a mostly unpaved road stretching from Limone Piemonte to Monesi di Triora. It's somewhat maintained, but don't let that fool you. This route is a wild one! You'll need a 4x4, good ground clearance, and nerves of steel. Trust me on this. Oh, and did I mention the road is often blocked by snow? Yeah, check the conditions before you even think about heading up there. There are hints of asphalt in some places, but mostly it's a rugged, bumpy ride. But hey, that's what makes it an adventure, right? Get ready for stunning scenery, but be prepared for a challenge!
extremeDriving the steep road to Berghaus Nagens
🇨🇠Switzerland
# Berghaus Nagens: A Serious Alpine Challenge Nestled at 2,172m (7,121ft) in Switzerland's Graubünden canton, Berghaus Nagens sits smack in the middle of the stunning Flims-Laax-Falera mountain playground. Fair warning: this isn't your typical Sunday drive. The 8km (4.9-mile) route from Flims is short but absolutely relentless. You'll be climbing 1,031 meters of elevation in those 8 kilometers—basically trading elevation for distance at a punishing rate. The gravel service track (used for chairlift maintenance and mountain infrastructure) hits a jaw-dropping 20% gradient at its steepest sections, with an average grade sitting around 13%. Buckle up for an intense mountain experience. Here's the catch: this road is off-limits to regular drivers. Only authorized mountain services and specialized vehicles can make the journey, so you'll need special permission or to hoof it on foot. The payoff? Absolutely breathtaking panoramic views. As you ascend these steep Alpine slopes, the entire Flims-Laax-Falera region unfolds beneath you—genuine, wide-open vistas of the Graubünden mountains in all their glory. One more thing to know: forget about visiting from September through June. Heavy snow blankets the track above 2,100m for most of the year, making it completely impassable. Plan your visit for the brief summer window when conditions allow.
hardConquering Theodul Pass on the Swiss-Italian Border
🇮🇹 Italy
# Theodulpass: Europe's Ultimate Alpine Challenge Want to experience one of Europe's most extreme mountain routes? Theodulpass sits at a jaw-dropping 3,336 meters (10,944 ft) on the Switzerland-Italy border, straddling the Valais canton and Valle d'Aosta. It's seriously high—and seriously intense. The pass goes by several names—Colle del Teodulo, Col de Saint-Théodule, Theoduljoch—but no matter what you call it, this is peak Alpine adventure. There's even a historic mountain hut, Rifugio del Teodulo, built back in 1920, waiting just above the summit. Here's the thing: this route is completely unpaved, and motorized traffic has been off-limits since 2009. But cyclists? You can still make it to the top if conditions are perfect and you're tackling it in midsummer. Before the ban, this was actually the highest motor-accessible point in the Alps. Talk about bragging rights. Starting from Breuil-Cervinia down in the Aosta Valley, you're looking at 10.5 km (6.5 miles) of pure climbing. You'll gain 1,308 meters of elevation with an average gradient of 12.45%—but here's where it gets gnarly: the steepest sections hit 30% gradient. The terrain? Loose stones that transition into increasingly rocky, unforgiving slopes as you climb higher. Nestled in the eastern Pennine Alps, this route demands respect and timing. You've got a narrow summer window—realistically only late August—when conditions are passable. This isn't a casual spin; it's the ultimate test for serious mountain enthusiasts.
moderateTiarms Pass: A Brutal 18% Gravel Climb in the Swiss Alps
🇨🇠Switzerland
# Tiarms Pass (Cuolm de Vi): Switzerland's Hidden Alpine Gem Want to skip the crowded main alpine routes? Then Tiarms Pass is calling your name. Sitting pretty at 2,161m (7,089ft) in central Switzerland, this local secret sits right above the famous Oberalp Pass and straddles the boundary between Graubünden and Uri cantons in the Glarus Alps. Here's the thing: this pass barely registers on most travelers' radars, overshadowed by its bigger sibling, but that's exactly what makes it so special for off-road adventurers and hikers seeking something genuinely wild. You'll be rewarded with stunning panoramic views stretching across the Surselva valley—the kind that'll make you forget why you ever bothered with the smooth, predictable main routes. The climb is short but absolutely brutal. Kicking off from the Oberalp Pass summit (2,044m), you're only facing 1.1 km (0.68 miles) of driving. Don't let that fool you though—this is one of the steepest, most intense short climbs you'll find anywhere in the region, and the entire road is a primitive gravel track that demands respect. Fair warning: this alpine playground stays buried under snow most of the year, so plan your visit between late June and October if you want a realistic shot at reaching the top. There's a cool bonus too—the climb starts near the world's highest lighthouse, a replica of the "Hoek van Holland" that marks the nearby source of the Rhine river.
