Year-round
Cruising through the Italian Piedmont region, just outside Turin, you'll find the wild Ceresole Tunnel. Nestled way up in the Graian Alps, right in Gran Paradiso National Park, this baby is a thrill!
Clocking in at 3.5km, this paved tunnel is part of the SP460 road. It's well-lit and roomy, but hold on tight because it's rumored to be the steepest tunnel in the Alps, with sections hitting a crazy 14-16% grade! You start at 1172m above sea level and climb to 1456m, gaining 284 meters in elevation. That's an average gradient of 8%!
If you're feeling adventurous, ditch the tunnel and take the old service road to the left. It's a repaved beauty (thanks, Giro d'Italia!) with three hairpin turns and views for days. Prepare for a challenging 10-15% slope, but the waterfalls, overhangs, and the Orco stream will totally make up for it. Get ready for an epic Alpine experience!

moderateA Paved Road to Rifugio Sapienza on Mount Etna
🇮🇹 Italy
# Rifugio Sapienza: Sicily's Gateway to Europe's Mightiest Volcano Perched at 1,935 meters (6,348 feet) on the southern slopes of Mount Etna, Rifugio Sapienza is the ultimate launchpad for volcano adventurers. This mountain lodge sits in Catania's Metropolitan City on Sicily, and it's where the magic happens—from here, you can catch the cable car up to even loftier heights on Europe's most active volcano. Getting there is half the fun. The fully paved Strada Provinciale 92 (SP92) stretches a solid 36.5 kilometers (22.68 miles) connecting Nicolosi and Zafferana Etnea. Don't let that distance fool you—this route is no casual Sunday drive. The road climbs relentlessly with some gnarly 13% grades in the steepest sections. Coming from Nicolosi? Buckle up for 19 kilometers of climbing with 1,223 meters of elevation gain (averaging 6.4% gradient). The Zafferana approach is even more intense—18 kilometers gaining 1,305 meters at an average 7.2% grade. The Giro d'Italia has tested cyclists here, and for good reason. The good news? The pavement is solid, and once you climb higher, the panoramic views are absolutely stunning. The not-so-good news? You're driving on the slopes of one of the world's most restless volcanoes. Etna's in a nearly constant state of activity, which means the road can shut down without warning. It technically stays open year-round, but Mother Nature has the final say. That's all part of the thrill.
hardHorcadina de Covarrobres
🇪🇸 Spain
Get ready for an off-road adventure in Northern Spain! Horcadina de Covarrobre is a high mountain pass sitting pretty at 1,930m (6,332ft) in Cantabria's Picos de Europa mountains. This isn't your average Sunday drive, folks. The road's gravel, rocky, bumpy, and can get pretty dicey. Snow usually hits hard from October to June, so plan accordingly. This trail is strictly for experienced 4x4 drivers only. If unpaved mountain roads aren't your thing, steer clear! The weather's super unpredictable (think freezing temps out of nowhere), so be prepared for anything. You're in the Picos de Europa National Park, so expect some serious elevation gain. A 4x4 isn't just recommended – it's a must. And if heights make you queasy, maybe skip this one. Keep an eye on the sky, thunderstorms can turn the roads impassable in a heartbeat. Plus, this place is teeming with wildlife – wild boar, ibex, chamois, and even wolves and bears! The road’s a constant rollercoaster of twists and turns that will test even seasoned drivers. On your way up, you'll pass Chalet Real, a mountain hotel with a royal history – King Alfonso XIII himself stayed here back in 1912! And at the start of the road, you’ll find Hotel Áliva. The views are insane, with Olvidada, Peña Vieja, Pico de Santa Ana, and Torre de los Horcados Rojos creating a stunning backdrop.
hardPuerto de la Morcuera
🇪🇸 Spain
# Puerto de la Morcuera Ready for some serious elevation gain in central Spain? Head to Puerto de la Morcuera, a mountain pass sitting pretty at 1,796 meters (5,892 feet) in the northern reaches of Madrid. The road up is called M-611, and while it's paved, don't expect smooth sailing—it's rough around the edges and gets genuinely steep in spots, with some sections hitting 11% grades. This climb has even been featured in Spain's legendary Vuelta race. You've got options depending on where you're starting from. Coming from Rascafría? That's a 14 km grind with 658 meters of elevation gain (average 4.7%). Prefer the shorter route from Miraflores de la Sierra? Go for the 9.2 km push that climbs 603 meters at a steeper 6.6% average. Or tackle the beast from Guadalix de la Sierra—17 km and 926 meters of elevation gain (5.4% average). Fair warning: this is high-altitude territory, so winter snowfalls are no joke. The road can shut down completely when snow takes over, so check conditions before you head up. It's all part of the adventure though, right?
extremeA brutally steep road to Alto del Gamoniteiro
🇪🇸 Spain
# Alto del Gamoniteiro: Asturias' Brutal Mountain Gem Tucked away in the Sierra del Aramo mountain range in northern Spain, Alto del Gamoniteiro sits at a whopping 1,776m (5,826ft) and claims the title of Asturias' highest paved road. If you're planning a visit, prepare yourself for one seriously epic ride. This isn't your average scenic drive. The 6.4 km (3.97 miles) climb from AS-230 packs 625 meters of elevation gain into its narrow, winding route—and it doesn't hold back. With an average grade of 9.76%, this road gets downright vicious in places, hitting a brutal 17% through the steepest sections. The final 1.5 km? Relentless suffering, averaging 12% with virtually no mercy. Fair warning: the road surface is sketch. We're talking crumbly asphalt, concrete patches, potholes, and hairpin turns that'll test your nerves. And if heights make you queasy, maybe don't look too far over the edge—the views are stunning, but they're also *very* long down. The climb is broken into three progressively harder sections, with that nail-biting final kilometer averaging 13.3%. Some call it Spain's answer to Mont Ventoux, minus the tourist hordes. At the summit, you'll find a small parking lot and communication towers—plus access to a short 2 km unpaved road leading to Lago de Cueva, a gorgeous high-altitude lagoon with 11 hairpin turns of its own. This is genuinely one of the most beautiful climbs in the region. Just bring your legs, your determination, and your sense of adventure.
