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!

🇨🇭 Switzerland
# Col de Bretaye Ready for an alpine adventure? Head to the Swiss Alps in Vaud canton and tackle Col de Bretaye, sitting pretty at 1,806m (5,925ft) above sea level. The route up—Chemin de Bretaye—is a paved path that doesn't mess around. This is a seriously steep climb that'll test your legs and your lungs, but the payoff is totally worth it. Once you've conquered the summit, reward yourself at the mountain restaurant up there. Nothing beats catching your breath with a hot drink while taking in those incredible alpine views.
hardRoad 626 is an awe-inspiring drive in the peninsula Westfjords
🇮🇸 Iceland
Road 626, or Hrafnseyrarvegur, is a coastal gem nestled in Iceland's Westfjords, specifically the Dýrafjörður fjord area. Think breathtaking scenery as you wind 30.6 km (19 miles) from Þingeyri to Dynjandi, passing by Hrafnseyri. Now, heads up, this isn't your typical paved road. It's all gravel, but most cars can handle it, though a 4x4 definitely makes things easier. This route can get feisty when the tide's high! Prepare for seriously stunning views of the coastline, mountains, and Hrafnseyrarheiði from both sides of the road. Plus, it's your access point for the gorgeous Gljúfurárfoss Waterfall. Just a heads-up: the road has some tight squeezes, a bumpy surface, steep climbs (up to a crazy 20% grade!), and drop-offs. You'll climb to a whopping 551m (1807ft) at the Hrafnseyrarheiði plateau. Because of the altitude, it's only open in the summer. Quick note: as of October 2020, the Dýrafjarðargöng tunnel (part of Road 60) offers an alternative route.
moderateLimni Gölü
🇹🇷 Turkey
Okay, wanderlusters, listen up! I've got a spot for you that's seriously off the beaten path: Limni Gölü in Turkey's Black Sea region. Picture this: a shimmering alpine lake perched way up high in the mountains. We're talking 2,407 meters (almost 8,000 feet!) of elevation, people. Now, getting there is part of the adventure. The road's gravel, so buckle up for a bumpy but beautiful ride. You'll definitely want a 4x4 for this one. Word to the wise: this road is typically closed from October to June due to snow, so plan your trip accordingly! But trust me, the panoramic views and the serene beauty of the lake are SO worth the trek. Get ready for stunning scenery!
moderateShell Island Causeway is covered by sea water at high tide
🇬🇧 Wales
Alright, adventurers, listen up! Ever dreamed of driving to a freaking ISLAND? Shell Island in Gwynedd, Wales, is calling your name! Picture this: you're cruising along a narrow causeway, with the wild beauty of Snowdonia National Park all around. But here's the kicker: this isn't your average road trip. Twice a day, the tide rolls in, and POOF! The road disappears under the waves. Seriously, it's underwater. So, timing is EVERYTHING. You gotta pay a toll to cross, and check those tide charts religiously (the official website is your best friend for this). Shell Island (also called Mochras) gets its name from the gazillions of seashells scattered across its beaches. The tidal causeway that links it to the mainland floods at high tide. Weather can also close access. Come during the summer and you’ll find it bursting with life. It’s a popular spot, and for good reason!
