# Port de Lers: A Pyrenean Gem Worth the Climb
Nestled in the French Pyrenees at 1,517 meters (4,977 feet), the Port de Lers is a stunning high mountain pass that'll make any road tripper's heart sing. Located in Ariège, this beauty is also known as Port de l'Hers or Port de Massat, and it's been tough enough to feature in the Tour de France multiple times.
The D18 is a fully paved route that connects three charming communities—Aulus-les-Bains to the west, Massat to the north, and Vicdessos to the east—with plenty of hairpin turns to keep things interesting. Fair warning though: you'll encounter some seriously steep sections (think double-digit gradients), so bring your A-game.
You've got two solid options for tackling this climb. Coming from Vicdessos is the shorter but spicier route at 11.5 km with 807 meters of elevation gain and some gnarly 10.9% stretches. If you prefer a steadier pace, head up from Massat's 16.6 km approach with 868 meters of elevation gain and more manageable 5.2% average grades (though the steepest bits still hit 8.9%).
Here's the best part: this is a year-round pass, so you can chase it in any season. Just keep in mind that winter can throw some curveballs with temporary closures, so check conditions before you go. About 3.8 km from the summit, you'll spot a junction with the Col d'Agnes climb if you're feeling extra adventurous.

extremeA wild balcony road through Gorges de Galamus in France
🇫🇷 France
# Gorges de Galamus: France's Heart-Pounding Canyon Drive Picture this: you're winding through the stunning Occitanie region in southern France, straddling the border between the Aude and Pyrénées-Orientales departments, carved into cliffs by the Agly River. Welcome to Gorges de Galamus, one of France's most legendary balcony roads. The D7 stretches a thrilling 9.7 km (6 miles) between Cubières-sur-Cinoble and Saint-Paul-de-Fenouillet, and honestly? It's not for the faint of heart. This paved road gets genuinely narrow—we're talking two-car-passing-impossible narrow. Those 1,000-foot drops to the river below are real, and the stone walls offer minimal reassurance. High winds are pretty much guaranteed, making it a road that demands respect and attention. Summer traffic can be intense. July and August bring afternoon traffic lights and potential 15-minute waits, thanks to alternating traffic regulations in place since 2003. Year-round driving is possible, but expect challenges. The road narrows so dramatically in places that you might need to reverse around blind corners, and beginner riders should honestly skip this one. The good news? Approximately every 100 meters there's a passing spot—handy since this road was originally built for horse-drawn carriages that literally couldn't turn around. The scenery is absolutely stunning, especially from the restaurant and parking area near Saint-Paul-de-Fenouillet. Just remember: you can't stop safely for the driver to enjoy the views while driving. Nearby, you can tackle two impressive castle ruins—Château de Peyrepertuse and Château de Queribus—plus the scenic "Grau du Maury" with its panoramic mountain vistas. All within 40 km of breathtaking driving. Just bring water on hot days, and watch out for storm winds.
extremeA narrow road with a 15% slope to Turó de l'Home
🇪🇸 Spain
# Turó de l'Home: Catalonia's Brutal Mountain Challenge Perched at 1,697 meters (5,567 feet) in Barcelona's Montseny Natural Park, Turó de l'Home—"The Mountain of Man" in Catalan—is one of those roads that'll test your nerves and your car's suspension in equal measure. The 5.5-kilometer climb from the BV-5119 is notoriously steep, with sections ramping up to a jaw-dropping 15%. Think of it as Catalonia's answer to Mont Ventoux, and it holds the unofficial title of the region's only hors catégorie pass outside the Pyrenees. You're looking at an elevation gain of 459 meters with an average gradient of 8.34%—basically, it's relentless. Here's the thing: the road is paved, but don't expect a smooth ride. Potholes and loose gravel litter the surface, and sections are genuinely narrow—rock walls on one side, sheer drops of hundreds of meters on the other. Not ideal if you're white-knuckling it already. Weekend traffic, especially during summer, can add another layer of chaos given its proximity to Barcelona. Winter brings its own drama: snow, ice, fog, and vicious winds can shut things down. The final 1.3 kilometers from Plana Amagada parking area (1,680m elevation) is gated off for cars but open to cyclists—though you'll have to hoof it with your bike for the final stretch to the actual summit. Up top, there's a weather observatory and a small bar where you can catch your breath. On clear days, the views stretch from the Mediterranean to the Pyrenees and even across to Mallorca's Serra de Tramuntana. Just remember: the mountain carries dark history. A Transair Dakota crashed here in 1959, killing all 32 aboard—a sobering reminder of these peaks' power.
hardDriving the wild road to Col de Balme
🇨🇭 Switzerland
# Col de Balme Want to experience some serious Alpine drama? Col de Balme sits pretty at 2,209 meters (7,247 feet) right on the France-Switzerland border, and it's absolutely worth the adventure. Here's the deal: the French side is where things get real. Think narrow, gravel roads with some seriously steep switchbacks that'll keep you on your toes. The Swiss side? That's basically hiking territory—just a walking path, really. You're connecting Trient (in Switzerland's Valais canton) to Argentière (French Haute-Savoie), so you've got a proper international crossing happening. The best part? There's this iconic stone alpine restaurant sitting right at the pass—you literally can't miss it. It's the perfect spot to grab hot chocolate, catch your breath, and soak in those jaw-dropping mountain views. Just a heads-up though: they're only open from late June through mid-September, so plan your visit accordingly. If you're into dramatic mountain scenery and don't mind a challenging drive on the French approach, this pass absolutely delivers.
moderateHarthope Moss is a very famous climb in England
🇬🇧 England
Okay, buckle up, fellow adventurers! Let's talk about Harthope Moss, a seriously epic mountain pass chilling at 2,060 feet above sea level in County Durham, England. Word on the street is, it's one of the highest paved roads you'll find in the country! Tucked away in the northeast, this pass splits Weardale from Teesdale and carves its way through the stunning North Pennines. The road to the top (also known as Chapel Fell) is paved, but don't let that fool you – it's STEEP! We're talking about a 4.8-mile stretch from the charming village of St John's Chapel (right on the River Wear) to Langdon Beck. Now, you can tackle this beast from either the west or the east, but either way, get ready for a climb! Coming from St John's Chapel? It's a 2.5-mile ascent with a whopping 1,119 feet of elevation gain! That's an average gradient of 8.3%, but hold on tight because you'll hit a brutal 16% in some spots. If you're starting from Langdon Beck, it’s a slightly longer 2.9-mile climb with 896 feet of elevation gain, averaging 5.3% with ramps up to 11%. But trust me, the views are worth every ounce of effort! You'll be treated to panoramic vistas of the Pennines. Just a heads up, the landscape is pretty wild and exposed, so expect some serious wind as you make your way up!
