Located between the Montsant range and the Prades Mountains, the pass is 21km (13.04 miles) long running south-north from Les Borges del Camp to Cornudella de Montsant. The road is steep in parts, hitting a 6-7% of maximum gradient through some of the ramps.

moderateThe Albanian Muhurr bridge is not for the faint of heart
🇦🇱 Albania
Okay, picture this: you're in northeastern Albania, near the tiny village of Muhurr in Dibër County. Get ready to cross the Black Drin River on one of the world's most spectacular bridges! This isn't your average overpass, folks. The Muhurr bridge is a cool mix of iron and wood, stretching 45 meters across the water. Now, the SH40 highway might as well be called "The Journey to Hell"—or, more dramatically, "The Wild Road to Qafe Vranice." This road is not for the faint of heart, but it's loaded with incredible views. Just keep your eyes on the road, and maybe say a little prayer!
moderateHow to drive the challenging access road to Pico del Teide?
🇪🇸 Spain
# Scaling Spain's Highest Peak: The Sendero Montaña Blanca Tenerife is home to Pico del Teide, Spain's most iconic volcano and the third-tallest in the world when measured from the ocean floor. On the island's eastern side, a rugged unpaved route climbs to 2,743 meters (8,999 feet)—making it one of Spain's highest roads and a serious mountain adventure. This is the Sendero Montaña Blanca, nestled in the heart of Teide National Park. It's a UNESCO World Heritage site that feels almost otherworldly, with lunar landscapes, dramatic geological formations, and hardy alpine vegetation clinging to life at extreme elevations. Here's the real talk: this isn't a casual Sunday drive. You'll need a 4x4 vehicle, and private cars aren't allowed—it's strictly regulated. Starting from the paved TF-21 road at 2,351 meters (7,713 feet), you've got a relatively short but seriously steep 4.6-kilometer (2.85-mile) push ahead of you. You'll climb 374 meters with an average gradient of 8.13%—so expect some intense switchbacks and rough terrain. The payoff? You'll finish near Refugio Altavista, perched impossibly high on the volcano's flank, with views that'll make your jaw drop and your legs ache in equal measure.

🇪🇸 Spain
# Collet de la Gralla: A Pyrenean Adventure Tucked away in the Ripollès region of Girona, Catalonia, near the Spanish-French border, sits the stunning Collet de la Gralla pass at 1,961 meters (6,433 feet). This isn't your typical paved highway—it's a rough-and-tumble mountain track called Camí de Fontlletera (GIV-5265) that demands respect and a proper vehicle. The 28.9 km route connects the charming villages of Ribes de Freser and Tregurà de Dalt, winding through the eastern Pyrenees with all the drama you'd expect from high alpine terrain. The scenery is absolutely worth it—think sweeping mountain vistas and that raw, untamed Pyrenean landscape that'll take your breath away (partly from the elevation, partly from the views). Here's the catch: this is serious mountain driving. The unpaved surface combined with frequent snow means you'll want to tackle this between late spring and early fall when conditions are most favorable. Definitely bring an SUV or proper all-road vehicle—regular cars need not apply. But if you're up for the challenge and prepared for mountain weather, this pass offers an unforgettable journey through some of Europe's most spectacular terrain.
hardThe road to Coll d’Honor is a hidden gem in Mallorca
🇪🇸 Spain
# Coll d'Honor: Mallorca's Thrilling Mountain Ride If you're looking for an adrenaline-pumping drive through Spain's Balearic Islands, Coll d'Honor in northern Mallorca is calling your name. Perched at 565m (1,853ft) in the stunning Tramuntana mountain range, this pass is pure driving adventure. The 19.3 km (11.99 miles) route stretches west to east between Bunyola and Alaró via the MA-2100 highway, and let's be honest—it's not for the faint of heart. You'll navigate 25 hairpin turns that'll keep your hands gripping the wheel and your eyes on the road. Fair warning: if you're sensitive to motion sickness, this might be the one to skip. The entire road is paved, though you'll notice some rough patches and cracked asphalt in spots—nothing that'll stop you, but definitely adds to the rustic character. Prepare yourself for some seriously narrow sections and steep climbs reaching up to 11.1% gradient. It's genuinely challenging, but in the best way possible. What makes this drive special is the scenery. You'll wind through beautiful woodland with views that make every hairpin turn worth it. Most drivers complete the route in 40 to 55 minutes without stopping—though you'll probably want to pull over for photos. The good news? It's open year-round, so you can tackle it whenever you please. Just head there outside peak summer and holiday seasons if you prefer fewer cars on the road. Otherwise, expect company and enjoy the ride.
