# Col de l'Iseran: The King of the Alps

Perched at 2,764m (9,068ft) in the Savoie department of southeastern France, Col de l'Iseran sits pretty in the Graian Alps, right near the Italian border. This legendary pass connects Val-d'Isère in the north to Bonneval-sur-Arc in the south, forming a crucial stretch of the famous Route des Grandes Alpes. (Fair warning: that sign at the top claiming 2,770m? Don't believe it.)

Nestled within Vanoise National Park, this is the stuff bucket lists are made of. Bikers and cyclists dream about this place—it's wild, intimidating, and absolutely epic. The landscape is raw and untouched, sweeping and desolate in the best possible way. It'll take your breath away.

The fully paved D902 road runs a stunning north-south course, climbing to one of the highest accessible roads in France. The catch? It's only open summer months—typically May or June through October—and on certain summer days, it's cyclists-only from Val-d'Isère. That's when you know a road is serious.

This pass has serious history too. It started as a mule track centuries ago before a 1920s presidential decree transformed it into an official route. Construction took a whopping 34 years, finally opening in 1937 under President Albert Lebrun. It was a massive feat—600 workers labored to connect the Maurienne and Iseran valleys for the first time ever.

The ride itself is no joke. The north side features galleries and tunnels with grades hitting 12 percent. Since 1947, it's been a Tour de France favorite, and distance markers line both sides to keep you oriented on your way up.

# Col de la Paré: A Wild Alpine Adventure Want to experience some serious French alpine terrain? Head to Col de la Paré, a stunning mountain pass sitting pretty at 2,412 meters (7,913 feet) in the Savoie department of southeastern France, near its neighbor Col des Rochilles. Here's the deal: this route isn't your typical smooth highway. Built between 1902 and 1907 for military operations, the Route Militaire des Rochilles still feels like stepping back in time. The road is mostly unpaved and pretty gnarly, so bring a 4x4 if you've got one—trust us on this. Starting from the Parking de 3 lacs just off the D902 road south of Valloire, you're looking at a compact but intense 4.8 km (2.98 miles) of pure mountain magic. Narrow, steep, and featuring 16 hairpin turns that'll keep you on your toes, this isn't a drive for the faint-hearted. Once you've conquered the switchbacks, the payoff is worth it. At the summit, you'll find the Ouvrage Les Rochilles, a fascinating remnant of the Maginot Line's Alpine fortifications, plus the cozy Refuge du camp des Rochilles where you can catch your breath and soak in the views. Fair warning: come winter, this road gets absolutely buried in snow and becomes impassable. Plan your adventure for warmer months when conditions are actually manageable.

Why is it called Rosi Mittermeier Tunnel?

🇦🇹 Austria

Okay, picture this: you're cruising through the Austrian Tyrol, heading up, up, UP into the Ötztal Valley. You're on the Panoramic Glacier Road (or Ötztal Glacier Road if you're feeling German), a 15km stretch of pure alpine bliss. Then, BAM! You hit the Rosi Mittermeier Tunnel, named after the legendary ski racer. This isn't just any tunnel; at 2,830m (9,285ft) high, it's said to be the highest road tunnel in Europe! It's a 1.729m paved tube connecting the Rettenbach and Tiefenbach Glaciers, both rocking huge car parks. Built back in '82, it's designed for two lanes each way, so even buses and trucks (up to 38 tons) can handle the 11% incline. But hey, a word of warning: this is serious mountain territory. The weather can flip on a dime, so be prepared for anything, especially snow. Snow chains are a smart move, and keep an eye out for potential road closures due to avalanche risk. Steel tracks may be required throughout the year. But trust me, the views are worth it!

🇦🇹 Austria

# Nockalmstrasse (Nockalm Road) If you're craving one of Austria's most stunning Alpine drives, head to Carinthia in the Karnten region and prepare yourself for the Nockalmstrasse. This 34km (21.12 miles) toll road stretches north-south from Innerkrems to Ebene Reichenau, winding through the incredible Nockberge National Park. Completed back in 1981, this lower alpine route is an absolute dream for drivers who love curves. We're talking 52 hairpin bends here—double that if you're doing the round trip! The road is silky smooth with beautifully spaced turns that make the whole experience feel effortless, even as it climbs at gradients up to 12%. Sitting in the heart of Carinthia's Nock Mountains, the road peaks at 2,042m (6,699ft) near Eisentalhöhe. You can tackle it from early May through late October, though fair warning: motorcycles are banned between 6:00 pm and 8:00 am. Weekends and holidays get pretty crowded, but if you go on a quieter day, you'll have plenty of chances for those jaw-dropping photographs. What makes this drive truly special is the landscape itself. The Nockbergs are famous for their distinctive rounded summits called 'Nocken'—you won't see anything quite like them elsewhere in the Alps. You're driving through Europe's only national park set in high mountains, surrounded by spruce and stone pine forests. Scattered along the route are charming mountain huts dishing up authentic Carinthian specialties, and viewpoints offering 360-degree vistas that'll take your breath away.

Where is Congosto de Jánovas?

🇪🇸 Spain

Okay, picture this: You're cruising through the Spanish Pyrenees on the N-260, aka the "Eje Pirenaico," and suddenly you're plunged into the Congosto de Jánovas. This canyon, carved by the Ara River, is seriously dramatic. The road hugs the cliffside, twisting and turning with hundreds of bends that locals affectionately call it the "Ruta del Retrovisor" (Rearview Route). Why's it so darn narrow? Blame a planned dam that never happened! Back in the day, they were gonna flood the whole area, so why bother improving the road? Now, it's a crazy-narrow 19.5 km (12.11 miles) stretch between Fiscal and Jánovas— barely wide enough for two cars to pass. Reversing skills? You'll need 'em! It's paved, thankfully, but watch out for rock slides! Despite the hazards, it’s popular, especially in summer, so expect some traffic. The scenery, though, is epic! Don't miss the viewpoint at Jánovas for killer views. Trust me, this drive is an adrenaline rush and a feast for the eyes!
