# The Lærdal Tunnel: Norway's Underground Marvel
Hidden beneath the mountains of Sogn og Fjordane county lies the world's longest road tunnel—and if you're claustrophobic, you might want to skip this one!
Stretching an impressive 24.5 kilometers (15.2 miles), the Lærdal Tunnel is an engineering feat that'll blow your mind. This two-lane highway carries the European Route E16, connecting the charming villages of Aurland and Lærdal while bypassing the stunning 47km Aurlandsfjellet—a scenic mountain route that's now optional for travelers.
Tucked in southwestern Norway, the tunnel is surprisingly quick to traverse. At the 80 km/h speed limit, you're looking at about 20 minutes underground—and here's the best part: it's completely toll-free. No hidden costs, no surprise fees.
Built in the mid-1990s and opening in 2000, this tunnel was designed to revolutionize winter travel between Oslo and Bergen by eliminating treacherous mountain passes and ferry connections. Smart move!
Here's where it gets interesting: the tunnel has no traditional emergency exits. Instead, engineers divided it into sections with wider chambers every 6 kilometers that create the psychological illusion of traveling through multiple tunnels. It's genius design mixed with psychology. The team even brought in specialists from SINTEF to tackle the monotony factor—they installed special lighting and fluorescent panels throughout to keep drivers alert and comfortable.
It's a thrilling drive through one of the world's most impressive pieces of infrastructure.

moderateWhere is Selleries Refuge?
🇮🇹 Italy
Okay, adventure awaits! Let's talk about the road up to Selleries Refuge in the Metropolitan City of Turin, Italy. This mountain hideaway sits pretty at 6,637 feet above sea level within the Parco Naturale Orsiera Rocciavrè, cradled by the Susa, Chisone, and Sangone valleys – think stunning Italian scenery! You'll find it in the northwestern part of the country, near some wild ravines. The journey begins from Strada Provinciale 23 del Colle del Lis. Now, the road to Selleries Refuge is a mix of paved and unpaved sections, so get ready for a little off-road action! Initially, there's a string of hairpin turns on a consistent climb, heading towards the crossroads for Selleries Refuge. After a couple more curves, the road evens out, but don't let that fool you. The climb is one to remember, especially the middle part. Get ready for some amazing views!
hardLago Torrei
🇮🇹 Italy
Lago Torrei is a mountain reservoir perched at 874m (2,867ft) in the heart of Sardinia, Italy. The 4.8 km stretch leading up to this alpine gem sits within the stunning Parco Nazionale del Golfo di Orosei e del Gennargentu, and honestly? It's every bit as thrilling as it is beautiful. Fair warning though – this road has earned its notorious reputation for good reason. While the asphalt is decent enough, it's narrow and unforgiving, with those classic hairpin curves that'll have you gripping the wheel. The real kicker is the exposure: sheer dropoffs plunge hundreds of meters straight down on either side, and there's barely a guardrail in sight to ease your nerves. It's the kind of drive that demands your full attention and respect. If you've got the nerve and the driving skills to match, the views are absolutely worth the adrenaline rush. Just take it slow, stay focused, and you'll have an unforgettable Alpine experience in one of Italy's most dramatic mountain regions.
extremeIf you love to drive, you’ll love the road to Madone d'Utelle
🇫🇷 France
Okay, picture this: the Madone d'Utelle, a mountaintop sanctuary chilling at 1,177 meters (3,861 feet) in the Alpes-Maritimes, France. Getting there? It's an adventure! The M132 is paved, but seriously narrow. Think "hold your breath and pray no one's coming" narrow. Reversing skills? Essential. Motorbikers, you'll love this! The M32 and M132 are hairpin heaven, steep as heck, and wonderfully tight. Just brace yourself for some traffic until you hit Utelle. This road is so epic, it's been featured in the Paris-Nice race! The climb is a leg-burner, reaching a max gradient of 14% in spots. From the M32, it's a 5.6 km push, gaining 357 meters, averaging a 6.37% gradient. Once you reach the sanctuary, the road tempts you onwards another 800 meters, even narrower now, to an orientation table (1,194m) and the TDF antenna. The payoff? Killer views of the mountains, Nice, and the sparkling sea. Seriously stunning stuff!
moderateWhere is Serrù Lake?
🇮🇹 Italy
Okay, picture this: you're cruising along the Strada Provinciale 50 (SP50) in Italy's Piedmont region, heading toward Lago Serrù. This isn't just any lake; it's a stunning, high-altitude reservoir sitting pretty at 2,275 meters (that's 7,464 feet!). You're smack-dab in the eastern Graian Alps, right between the Aosta Valley and Piedmont, and inside the Gran Paradiso National Park – nature overload in the best way possible! The road itself is paved, but hold on tight – you'll be tackling some seriously steep sections, with gradients hitting up to 12.3%. Weekends in the summer can get crazy busy, so plan accordingly. Just a heads-up, this road is typically closed from October 15th to May 15th due to snow. And on Sundays in July and August, the last six kilometers are often closed to cars. But trust me, the views are absolutely worth the effort. You're surrounded by those amazing Alps, so get your camera ready!
