elevation gain of 634 meters

average gradient of 11.32%

hardFronza alle Coronelle Refuge
🇮🇹 Italy
Okay, adventure seekers, listen up! Rifugio Fronza alle Coronelle – or Kölner Hütte if you're feeling German – is calling your name! Perched way up in the Italian Dolomites at a lofty 2,341 meters (that's 7,680 feet!), this mountain refuge is an absolute must-see. Now, getting there is... an experience. Think gravel, rocks, and a whole lot of bumpiness. Seriously, this isn't a Sunday drive in the park. It's more like a chairlift trail repurposed as a road. And a steep one at that! Be warned: this route is typically snowed in from October until June, so plan accordingly. Also, if heights aren't your thing, maybe skip this one. But the views? Totally worth the white knuckles. Prepare for some seriously breathtaking scenery!
hardHow Long is Dasdana Pass?
🇮🇹 Italy
Okay, picture this: you're cruising through the Italian Alps in Brescia province, and you stumble upon the Passo del Dasdana. This isn't your average Sunday drive, folks. We're talking about Strada Provinciale 345B, or as the locals call it, Delle Tre Valli, a wild 17.4 km (10.81 miles) stretch of road that will leave you breathless – both from the views and the sheer drop-offs. Most of the road teeters over 2,000 meters, clinging to the mountainside. Imagine soaring above it all! But fair warning: this road can get narrow, sometimes only wide enough for a single car, and those "guardrails"? Yeah, not so much. The road starts and ends paved, but the middle throws a little gravel curveball at you. It's still totally doable, just watch out for those rocks, especially when you're hugging the curves. And hey, keep it slow and steady at 20 km/h; no passing allowed and pull over only where you're supposed to, okay? But seriously, the scenery is absolutely worth it. Prepare for some major wanderlust!

And get this, the river is called "Gritos" (shouts) because of the awesome echoes in the canyon! The drive is only about 6.8 km (4.22 miles) from Valeria to Valeria de Abajo, but every kilometer is pure magic. You're surrounded by towering mountains and sprawling valleys, a total feast for the eyes. The landscapes have got a contrasting topography, with its vast plains and exquisite valleys, amplifies the region's immense beauty and allure. This road is a must-do if you're anywhere nearby!

It can be visited by making an appointment at the Deifontes town hall and with a guide service. The summit hosts a natural viewpoint called Mirador Cañada Larga, with stunning views.

Starting from Collado del Torreón (Camino a Iznalloz) the road to the summit is 6km long. The average gradient is 9.6% hitting a maximum gradient of 10% through some of the ramps.It's a really tough climb.
