# Susten Pass: One of the Swiss Alps' Most Iconic Drives
If you're a road trip enthusiast, the Susten Pass needs to be on your bucket list. Sitting pretty at 2,264 meters (7,428 feet) above sea level in Switzerland, this legendary Alpine route connects the Reuss Valley with the Hasli Valley, straddling the border between Uri and Bern cantons. Near Innertkirchen, it links up with the Grimsel Pass—making it part of the famous "Big 3" passes that every Alpine driver dreams about tackling.
The history here is seriously cool. What started as a 17th-century mule-train trading route evolved into something special. Construction began in 1938 and wrapped up in 1945, then the road officially opened on September 7, 1946, as the very first Alpine pass road purpose-built specifically for cars. And boy, did they build it right—25 bridges and 25 tunnels of engineering marvel, including a 300-meter tunnel right at the summit. At the time, people called it one of Europe's most beautiful roads, and honestly? They weren't wrong.
The 44-kilometer (27-mile) route runs east-west from Wassen to Innertkirchen on the fully paved Road 11, and it's a seriously fun drive. Expect plenty of hairpin turns, dramatic gradients hitting 10%, and some genuinely heart-pounding moments. Both approaches are equally thrilling, though the eastern side is slightly longer and a touch gentler. The real showstopper? The stunning views of the Stein Glacier on the southern slopes—absolutely worth the white-knuckle driving.
Fair warning though: the pass closes from November through June, and daily closures happen from 6 PM to 8 AM. Plan accordingly, and you'll have an unforgettable Alpine adventure.

extremeDriving the fantastically twisty road to Torri di Fraele
🇮🇹 Italy
# Torri di Fraele: A Mountain Adventure Not to Miss Want to experience one of Italy's most thrilling mountain drives? Head to the Torri di Fraele fortress in the province of Sondrio, nestled in Lombardy's Parco Nazionale dello Stelvio, near the Swiss border. This place has serious history—the towers were first built way back in 1391 to protect against invasions, then rebuilt in the 15th century. (Fair warning: the ravine below has a pretty grim nickname, "Burrone dei Morti," or ravine of the dead, so the stakes were real back then.) Starting from Turri Piano just west of Bormio, you've got 8.38km of pure adrenaline ahead. The road climbs 600 meters with an average gradient of 7.1%—and yeah, some sections get steep at 12%. The highlight? Those famous 18 hairpin turns that make this route the "Mini Stelvio." It's just as dramatic as it sounds, and since the road's been fully paved since 2010, you can actually enjoy the ride without worrying about your car. The drive takes about 25 minutes if you're moving, but honestly, you'll probably want to stop and soak it in. You'll pass through two short tunnels carved right into the mountainside before reaching the towers themselves. The views are absolutely spectacular—especially from in front of the towers where you get a panoramic shot of the entire road snaking down the mountain. Once you reach the towers, keep going another 1.6km on gravel (totally doable in any regular car) to check out Lago di Cancano and Lago di San Giacomo. These artificial lakes were built for hydroelectric power, and they're connected by a massive dam you can actually drive across. Fair heads-up: vehicle traffic is restricted here during July and August, so plan accordingly. This route was engineered between 1926 and 1927 as a feat of Italian construction genius, and it's even been featured in the Giro d'Italia. If you're already conquering the Stelvio and Gavia passes near Bormio, you absolutely have to add this one to your list.
hardHistory: The Destroyer of Pompeii and its Current Status
🇮🇹 Italy
Okay, picture this: you're in Southern Italy, gazing out over the Bay of Naples, and there it is – Mount Vesuvius. This isn't just any mountain; it's a notorious, active volcano, famous for *that* eruption that buried Pompeii and Herculaneum way back when. You can actually drive up this thing! The SP114 road winds its way up, giving you incredible views the whole time. The paved road takes you up to about 1,007 meters (3,303 ft), to a parking area. Here's the catch: you can't just drive all the way to the top in your own car. Private vehicles have to stop at a parking lot around the 800-meter mark. From there, you hop on a mandatory shuttle bus (yes, you gotta pay extra) for that final stretch to the top. And guess what? You can't even hike to the crater on your own. You need to book a ticket in advance and join a guided tour with the park rangers. They're your mandatory escort, making sure you don't wander off and become a geological statistic. A few things to keep in mind: definitely book your tickets online beforehand – they don't always sell them on site. Cell service is pretty much non-existent up there. Also, parking is super limited, so get there early, especially during the busy season. Basically, getting to Vesuvius is a mix of easily accessible driving and restricted access. You can get close but you have to surrender and follow the rules. This is all done to ensure safety!
extremeThe Extreme 4x4 Service Road Network
🇫🇷 France
Okay, picture this: you're in the French Alps, Haute-Savoie to be exact, near the super cool Flaine ski resort (think Bauhaus architecture meets Picasso sculptures!). But forget the slopes for a minute, because lurking above is a gnarly network of service roads that lead to Tête de Veret. This isn't your average Sunday drive! We're talking a 5.7 km (3.54 mile) ascent on a brutally unpaved track that's usually off-limits. But if you manage to get permission (and you *really* should have a good reason to be up there), prepare for a serious 4x4 adventure. The gradient hits a max of 21% in places, so high clearance and four-wheel drive are non-negotiable. Expect steep, rocky terrain and major exposure – this climb isn’t for the faint of heart. Strong winds are practically a year-round feature. The track connects a bunch of killer viewpoints. First, you'll hit Col de Vernant at 1,967 m (6,453 ft), the start of the serious climbing. Then you move on to Tête du Pré des Saix at 2,107 m (6,912 ft), which has some seriously narrow and exposed sections. Next is Col des Grands Vans at 2,198 m (7,211 ft) - this is a treacherous section prone to rockfall! Finally, you'll reach Tête de Veret itself at 2,309 m (7,575 ft)! It's the highest point, completely exposed, with 360-degree views that stretch as far as the eye can see (if the weather cooperates, that is!). Speaking of weather, this road is usually closed from October to June due to snow and ice. Even in summer, heavy mist can roll in, making visibility a nightmare. But if you catch it on a clear day? You're in for an unforgettable alpine experience!
hardRadomir
🇬🇷 Greece
# Radomir Pass: A Thrilling Alpine Adventure Perched at a breathtaking 2,031 meters (6,663 feet) above sea level, Radomir Pass sits right on the Bulgarian–Greek border within the stunning Belasica mountain range. This isn't your typical scenic drive—it's a genuine off-road adventure for those who live for rugged terrain. The journey to the summit is pure grit: think gravel, rocks, ruts, and bumpy stretches that'll keep you on your toes. This is definitely 4x4 territory, and honestly, it's not the place to learn mountain driving skills. The road gets genuinely steep in sections, and if you're uncomfortable with heights or unpaved mountain roads, you'll want to skip this one altogether. Expect dramatic Mediterranean-influenced weather that can throw curveballs your way. Wet conditions transform the muddy track into a serious challenge, and winter? Forget about it—the pass becomes virtually impassable when snow and ice roll in. Plan your trip for warmer months if you want any shot at making it through. The payoff? Incredible scenery and the satisfaction of conquering one seriously unforgiving road. Just know what you're getting into: this pass demands respect, a capable vehicle, and genuine off-road experience. Named after Bulgarian Emperor Gavril Radomir, who fought in the legendary battle of Kleidion in these very mountains, Radomir Pass is a route with real history—and a real challenge.
