# Observatorio de Sierra Nevada
Tucked away in the mountains of Granada, Andalusia, the Observatorio de Sierra Nevada sits at a breathtaking 2,885 meters (9,465 feet) above sea level. This is serious altitude territory—the kind of place where the air gets thin and the views get infinite.
Getting up there is an adventure in itself. The road is pure gravel and rock, often tippy and bumpy, and it's basically off-limits from October through June unless conditions are perfect. When Mother Nature says no, she really means it. The steep grades, unpredictable weather, and extreme elevation make this route genuinely challenging and not for the faint-hearted.
Once you make it to the top (if you dare), you'll find an impressive setup operated by the Instituto de Astrofísica de Andalucía. The main building houses two seriously powerful optical telescopes—a 1.50-meter and a 0.90-meter—plus various other astronomical equipment and research facilities.
Good news for stargazers: the observatory actually welcomes visitors during the summer months of July and August, so you don't have to be an astronomer to experience this incredible place. Fair warning though—this is legitimately one of Spain's highest mountain roads, so come prepared for thin air, dramatic weather shifts, and a genuinely thrilling drive.

moderateThe road with 25 hairpin turns to Macahel Gecidi
🇹🇷 Turkey
Okay, adventure seekers, listen up! I've got a killer road trip idea for you: Macahel Gecidi, a mountain pass that'll blow your mind. Picture this: you're cruising through Artvin Province in Turkey's Black Sea region, almost close enough to wave at Georgia. This isn't your grandma's Sunday drive though! We're talking about a fully paved road – Borçka Camili Yolu – that climbs to a dizzying 1,821m (5,974ft). Get ready for a wild ride packed with hundreds of twists and turns, including a whopping 25 hairpin bends. If your travel buddies get carsick easily, maybe pack some ginger ale! The pass stretches for almost 40km (25 miles) from Borçka up to Düzenli. Word of warning: winter can be brutal up here, so expect closures. And hold on tight, because this route gets seriously steep in places, hitting gradients of up to 25%! But trust me, the incredible scenery makes it all worthwhile.
extremeWhere is Mortirolo Pass?
🇮🇹 Italy
Mortirolo Pass: Prepare for a challenge in the Italian Alps! This road, also known as Strada del Mortirolo or SP81, snakes its way between Brescia and Sondrio provinces, topping out at a lung-busting 1,878m (6,161ft). Located in the Lombardy region near the Swiss border, this 23.7 km (14.72 mile) stretch from Mazzo di Valtellina to Monno isn't for the faint of heart. The Mortirolo climb is notorious for its savage gradients, hitting a maximum of 26%! Forget about easy turnarounds; this narrow road doesn't allow them, and 3-axle vehicles are a definite no-go. This is serious cycling territory, a favorite of the Giro d'Italia. You'll average over 10% gradients, making it arguably Italy's hardest climb. Look out for the memorial to Marco Pantani, "il Pirata," near the summit. Allow about an hour to drive it non-stop. The views are amazing. For an even wilder ride, a super-narrow, extremely dangerous road branches off at the summit towards Aprica (Valico di Trivigno). This insane 28.5km (17.70 mile) route is paved (barely!) and crazy steep, with sections around 20%. Keep your speed under 20 km/h – and definitely leave the trucks at home. Closed in winter, this old military track rewards the brave with incredible vistas.
moderateWhere is the road to Passo Castrin?
🇮🇹 Italy
Okay, buckle up for Passo Castrin (aka Hofmahdjoch) in stunning South Tyrol, Italy! This hidden gem sits way up in the Ortler Alps at 1,781m (5,843ft). So, where does SP-86, the road across Passo Castrin, take you? It's a sweet 17km stretch linking the charming villages of Laurein and Santa Valburga. Think modern marvel, because the tunnels carved out in the 90s made this route a breeze compared to the olden days. Now, don't let the smooth pavement fool you; this road is a BEAST! We're talking hairpin turns and a gut-punching maximum gradient of 19%! Seriously, double-check those brakes before you head down. Despite the challenge, the pavement is pristine, making it a haven for cyclists and drivers chasing an adrenaline rush in the Dolomites. But here's the kicker: forget sweeping vistas at the summit. Passo Castrin's highest point is actually INSIDE a tunnel! Yep, you read that right. The peak elevation is at the south entrance of the main tunnel, making it a truly unique Alpine experience. Pro tip: control your speed and use engine braking on those crazy steep sections. The tunnel's well-lit, but be ready for the light change as you blast in from the bright Italian sun. It's a super direct and scenic shot through the mountains, giving you a fast and unforgettable drive through the Bolzano province.
moderateGerlitzen Alpine Road is a sensational drive south of the Alps
🇦🇹 Austria
# Gerlitzen Alpe Panoramastraße Tucked along the northern shore of Lake Ossiach in Carinthia, Austria, the Gerlitzen Alpe Panoramastraße is a scenic toll road that's absolutely worth the drive. The name itself has a fiery backstory—it comes from the ancient Slavonic word "Gorelice" (goreti = to burn), a nod to the region's history with wildfires. This 12km (7.45 miles) route starts near Bodensdorf, right by the lake, and climbs steadily upward to a panoramic car park perched at 1,773m (5,816ft) elevation. You'll gain a serious 1,258 meters of elevation along the way, which translates to an average gradient of about 10.48%—with some sections hitting a punchy 13%. The road itself is fully paved (though it's seen better days) and pretty narrow at just 5 meters wide, but that's part of its charm. As you wind your way up, you're treated to gorgeous views of the Ossiacher Sea below and the stunning Carinthian landscape unfolding around you. The drive culminates near the Mountain Resort Feuerberg, where that panoramic car park offers some truly breathtaking vistas of central Carinthia. It's the kind of road that justifies a leisurely afternoon—take your time, soak in the views, and enjoy one of Austria's most scenic drives.
