Year-round
Alright thrill-seekers, listen up! If you're ever cruising around Réunion Island (that little gem east of Madagascar), and you fancy a real adventure, you NEED to check out the Tunnel de Peter Both.
Carved way back in 1960, this tunnel punches a 166-meter hole through the mountains on the Route Nationale nº5, connecting Saint-Louis and Cilaos. Now, here's the kicker: it's NARROW. Think "cozy" rather than "spacious." Seriously, two cars at once? Forget about it! And with a height of only 3 meters, watch those oversized vehicles!
The road surface is paved, so that's a plus. But the real draw is the sheer audacity of the thing, and the killer views you get on either side. Just be prepared for a tight squeeze and maybe a little heart-pumping action. Trust me, it's worth it for the bragging rights!

moderateWhere is Pointe du Bouchet?
🇫🇷 France
Okay, buckle up, adventure lovers, because Pointe du Bouchet in the French Alps is calling! Perched way up high in the Savoie department, we're talking 3,229 meters (that's almost 10,600 feet!) of pure mountain majesty within the Vanoise National Park. This isn't your typical Sunday drive, though. The road to the top? It's a rugged, unpaved chairlift access road that starts from Plan-Bouchet. The climb stretches for about 5.6 kilometers (or 3.5 miles), and trust me, you'll feel every meter of the 818-meter climb! The average gradient hits almost 15%, so be prepared for a workout. Oh, and a heads-up: winter turns this road into a snowy wonderland that's completely off-limits. But come summer, the views are breathtaking, the air is crisp, and the bragging rights? Totally worth it!
hardPas de Cherferie
🇫🇷 France
Okay, adventure-seekers, listen up! Pas de Cherferie in the French Alps is calling your name! This insane gravel track in Savoie tops out at a cool 2,142 meters (that's over 7,000 feet!). Word to the wise: you NEED a 4x4 for this one, and forget about it in the winter – it's totally impassable. Expect some seriously narrow and steep bits as you climb. The views? Absolutely worth the white knuckles, but be prepared for a wild ride!
hardCampogrosso Pass
🇮🇹 Italy
# Passo di Campogrosso: A Heart-Pounding Alpine Adventure Nestled at 1,464 meters (4,803 feet) on the border between Trentino-Alto Adige and Veneto, Passo di Campogrosso is not for the faint of heart—or the queasy of stomach. This is a road that demands respect. The Strada provinciale 99 (SP-99) is a narrow ribbon of asphalt that clings to the mountainside with relentless hairpin turns and a punishing maximum gradient of 16%. Experienced drivers will find themselves gripping the wheel tightly as the road twists left, then right, then left again in a dizzying dance up the mountainside. Two small tunnels carved straight into the rock add an extra element of excitement to the journey. **Fair warning:** if anyone in your car struggles with motion sickness, this might not be the best choice for a family day out. The endless switchbacks and steep climbs can test even the strongest stomachs. You've got two options to tackle this beast. Coming from Recoaro, you're looking at a 12.19 km climb gaining 1,019 meters with an average gradient of 8.4%. Prefer a gentler approach? Start from Valli del Pasubio for a longer 17.53 km ascent with 1,122 meters of elevation gain averaging 6.4%. One heads-up: the Strada del Re section (km 11 to 14.8 on SP-99) is currently closed to traffic, so plan your route accordingly. This is mountain driving at its most thrilling—buckle up and enjoy the ride.
moderateAn old military road to Tremalzo Pass
🇮🇹 Italy
# Passo del Tremalzo: A WWI Adventure Road Want to drive through history? Head to Passo del Tremalzo, sitting pretty at 1,845m (6,053ft) in the Italian Alps, right where Trentino and Lombardy meet near the stunning Garda Lake. This isn't just any mountain pass—it's a piece of WWI heritage that'll blow your mind. Back in the Great War, Italian soldiers realized they needed a faster way to move artillery up the mountain to face the Austrians dug in on the northern side. So they transformed old footpaths into the "Strada della Grande Guerra" (Road of the Great War)—a rough, unpaved route that's still standing today. Fair warning: this isn't a drive for your regular sedan. You'll need serious off-road cred—think early Panda 4x4, Jimny, Defender, or similar beasts. The 10.6 km (6.58 miles) stretch from Rifugio Garda to Rifugio Alpini Passo Nota is pure dirt, beautifully rough, and demands respect. Expect hairpin turns with gradients up to 22%, a handful of rock tunnels, and jaw-dropping views of Garda Lake that'll make you forget how slowly you're crawling (seriously, 5-10 kph is the norm here). Here's the catch: only tackle this between late spring and early fall—snow dominates from November through April. Plus, the southern flank has been off-limits to vehicles since 2015. And proceed cautiously—rockslides are frequent, and maintenance is minimal. Worth it? Absolutely.
