# Colla d'Onzo: A Thrilling Mountain Challenge
Ready for one of Italy's most intense driving experiences? The Colla d'Onzo mountain pass sits at 843m (2,765ft) in Liguria's Province of Savona—and it absolutely lives up to its reputation as a seriously demanding ride.
This 7.9 km (4.90 miles) stretch connecting Nasino to Capitolo-Costa runs straight up the mountainside with a relentless 10.24% average gradient. But here's the kicker: some sections kick up to a brutal 20%, making this pass no joke for unprepared drivers.
What makes it truly gnarly? The road is absurdly narrow—two medium-sized cars literally can't pass each other. You'd better be comfortable with tight reversing maneuvers, because you'll likely need them. Throw in mixed paved and unpaved sections, and conditions that get sketchy after rain, and you've got yourself a serious challenge.
Low-clearance vehicles? Skip this one entirely. The steep, winding terrain demands respect and solid driving skills. But if you're up for it, you'll experience one of northern Italy's most spectacular and unforgiving alpine routes—the kind of drive that gets your heart pumping and leaves you with an unforgettable story.

easyWhere is the Kalser Glocknerstrasse?
🇦🇹 Austria
Alright, adventure seekers, listen up! If you're cruising around the Austrian Tyrol, you NEED to experience the Kalser Glocknerstraße. Tucked away in the southwestern part of the country, inside the Hohe Tauern National Park, this paved beauty is only about 7km (4.34 miles) long, but packs a serious punch. Starting from Burg (a district of Kals) this well-maintained mountain road winds like crazy through forests and past seriously lush meadows. Trust me, you'll be snapping pics around every hairpin bend! It'll take you into the Ködnitz Valley, all the way to the "Glocknerwinkel" car park. The drive starts in Burg, and climbs up to around 1,920 meters above sea level. Heads up: It's open year-round, but winter driving equipment is a MUST when the snow flies. Is it worth the drive? A resounding YES! You'll soak in views of glacier-carved valleys, daunting peak summits, and wild, rugged landscapes. And the grand finale? Jaw-dropping views of the Großglockner – Austria's highest mountain. Seriously, it's an Alpine experience you won't forget!
moderateWhy is Stara Baska famous?
🇭🇷 Croatia
Okay, picture this: you're cruising along ŽC 5125, a sweet little paved road clinging to the southernmost tip of Krk Island in Croatia, near the village of Stara Baška. This isn't just any drive; it's a coastal dream! Think sweeping views of the Adriatic, the kind that make you want to pull over every five minutes to snap photos. The road stretches for about 13 kilometers (8 miles) from Kornić down to Stara Baška, a tiny, historic beach town. Fair warning: it's a bit of a roller coaster! You'll climb to 184 meters (603 feet) above sea level, tackling some seriously steep sections – we're talking gradients up to 14% in places! The hills here are bare, thanks to the winds, but the real hazard is parking. During summer, everyone wants a piece of that Stara Baška beach, so cars line the road. Watch out, or you might get a ticket. But hey, the incredible coastal scenery and island views definitely make it worth the adventure!

Also known as Colle del Piccolo Moncenisio, it's nestled in the Rhône-Alpes region and home to the charming Refuge du Petit Mont Cenis nearby. Here's the fun part—legend has it that Hannibal himself might have marched his elephants through this very pass during his epic Alps crossing. Whether that's historically accurate or not, it definitely adds some adventure vibes to your drive! The road itself is mostly paved but pleasantly narrow, keeping things interesting without being intimidating. You'll find the asphalt in solid condition, and traffic is typically light, so you won't be fighting crowds. The climb stretches 7.9 km (4.90 miles) starting from Col du Mont Cenis, with excellent scenery the whole way up. If you're feeling extra adventurous, there's a short gravel road just north of the pass that pushes even higher—all the way to 2,216m (7,270ft)—for those who want to squeeze out every last meter of elevation. It's the kind of drive that blends history, gorgeous mountain landscapes, and the satisfaction of conquering Alpine terrain without needing nerves of steel.
