# Lac de Plan d'Aval: A Short but Seriously Steep Alpine Climb
Tucked away in the Savoie department of France, Lac de Plan d'Aval sits pretty at 2,041m (6,696ft) elevation within the stunning Vanoise National Park. The drive up here? It's short, sweet, and absolutely brutal in the best way possible.
This scenic alpine route starts in the charming village of Aussois and climbs 6.8 km (4.22 miles) with a whopping 558 meters of elevation gain. Don't let the distance fool you—the average gradient hangs tough at 8.20%, with sections pushing up to 11.8%. It's the kind of road that'll make your calves (and your brakes) work for every meter of altitude.
Built between 1945 and 1956 as part of the region's hydroelectric boom, the D108 (Route des Barrages) has evolved into a favorite playground for hikers, mountain bikers, and anyone who loves a challenge. The road itself is fully paved and well-maintained, winding through some seriously gorgeous mountain scenery as you climb toward the twin dams.
When you finally reach the parking area between the two reservoirs, the payoff is worth every switchback. Picture turquoise waters surrounded by the dramatic peaks of the Massif de la Vanoise—it's absolutely breathtaking.
One heads-up: this southern-facing route gets hammered by winter snow, so expect closures during the colder months. And if you're coming down on a bike or in a vehicle with manual transmission, go easy on those brakes—they'll be smoking by the time you hit Aussois again.

moderateIs the Road to Tris Ekklisies Crete's Most Thrilling Coastal Drive?
🇬🇷 Greece
# Tris Ekklisies: A White-Knuckle Adventure to Paradise Tucked away in southern Crete, about 60-65 km south of Heraklion, the tiny beach town of Tris Ekklisies (literally "Three Churches") is one of Greece's best-kept secrets. And getting there? Well, that's half the adventure. The 5.6 km road from Paranimfi to this hidden gem isn't playing around. Yes, it was paved in 2017, but don't be fooled—this isn't your typical coastal drive. You're climbing 458 meters with an average gradient of 8.17%, hitting peaks of 10% on some of the steeper sections. Oh, and there are 19 sharp hairpin turns waiting to test your driving skills. Fair warning: if anyone in your car gets motion sickness easily, this probably isn't the trip for them. The dramatic backdrop? Totally worth it. As you snake through the wild, barren Asterousia Mountains, you'll get jaw-dropping coastal vistas of the Libyan Sea that'll make every hairpin turn feel like a small price to pay. The payoff is a stunning, relatively untouched beach with coarse sand and impossibly clear, deep waters—the kind of place that makes you feel like you've discovered something special. One heads-up: the road can close unexpectedly due to rockslides, so it's worth checking conditions before you head out. But if you're an adventurous driver who doesn't mind a bit of an adrenaline rush, Tris Ekklisies is calling your name.

🌍 Denmark
Okay, picture this: You're cruising along Route 70 in the Faroe Islands, and BAM! Instant postcard-worthy views. This road is a stunner, hugging the dramatic coastline for almost 16 kilometers. You'll start near Klaksvík, a busy fishing town on Borðoy island, and wind your way to Viðareiði, hands down one of the prettiest villages you'll ever see. Seriously, it's the northernmost spot on the islands, perched on Viðoy. Now, heads up! You'll be navigating a couple of those classic Faroese one-lane tunnels—the Hvannasundstunnilin (2.1 km) and the Árnafjarðartunnilin (1.7 km). Keep your eyes peeled and be ready to yield—it's all part of the adventure!

hardA scary road from Carzano to Peschiera Maraglio
🇮🇹 Italy
# The Lakeside Road That'll Make Your Heart Skip a Beat Want to test your nerves? Head to Monte Isola on Lake Iseo in Brescia province, where the tiny road connecting Carzano and Peschiera Maraglio will do exactly that. At just 2.3km long, this narrow asphalt strip is barely wide enough for one vehicle—and here's the kicker: there are no guardrails between you and the water. This isn't your typical scenic drive. As you creep along the shoreline, you'll feel like you're practically *in* the lake rather than driving beside it. The views are genuinely stunning—water stretching out on one side, mountains on the other—but if you're the type who gets queasy near heights or exposed edges, you might want to skip this one. There's nowhere to pull off and decompress either, so you're committed once you start. The road itself is paved and relatively smooth, but the real challenge is psychological. Your wheels have plenty of clearance, but the mind plays tricks when there's nothing between you and a water drop-off. Most drivers who aren't bothered by exposure breeze through without a second thought. For everyone else? Well, let's just say those 2.3 kilometers will feel like the longest drive of your life. If you can't handle no guardrails and lake dropoffs right at your door, do yourself a favor and take a different route. Your stress levels—and your passengers—will thank you.
