# Col de la Pierre Saint-Martin: Spain and France's Hidden Pyrenean Gem

Ready for one of the most thrilling drives in the Pyrenees? The Col de la Pierre Saint-Martin sits at 1,760 meters (5,774 ft) on the French-Spanish border, connecting the Pyrénées-Atlantiques in southwestern France with Navarre in northern Spain. And trust us—this isn't your typical scenic mountain pass.

Spanning 52 kilometers (32 miles) between the French town of Arette and the Spanish village of Isaba, this fully paved route (D132 on the French side, NA-1370 on the Spanish side) is an absolute masterclass in dramatic driving. We're talking narrow sections, endless switchbacks, and a seriously famous pigtail turn called the *Nudo de Corbata*—a mind-bending 270-degree loop that passes under itself. It's the kind of curve that makes you laugh and white-knuckle the steering wheel simultaneously.

The climb is genuinely steep: 11% max gradient on the French side, 7.4% on the Spanish side. You'll earn every meter of elevation gain. Though it might not quite rival legends like Tourmalet or Hautacam in difficulty, the jaw-dropping scenery—dramatic western Pyrenean peaks, contrasting landscapes, and endless panoramic views—absolutely matches them.

The payoff? A huge parking lot at the summit and the bragging rights of conquering one of Europe's most spectacular mountain roads. Fun fact: cyclists have tackled this beast during Tour de France stages, and it's one of only five Spanish roads featuring a pigtail turn.

Cerrada de la Magdalenamoderate

Cerrada de la Magdalena

🇪🇸 Spain

Okay, picture this: you're cruising along the sun-drenched Sierra de Cazorla, just north of Granada, Spain. The road? Cerrada de la Magdalena. It's not paved – think gravel, and pretty darn narrow at that. This isn't a Sunday drive; it's an adventure! The drop-offs are real, so keep your eyes on the road, especially around those blind corners. You don’t want to meet another car head-on! Nestled inside the Sierra de Castril Natural Park, it's usually manageable when dry, but after rain? Mud city! It can get seriously slippery, even impassable, so check the weather before you go. The whole stretch is only about 11.3 km, but those kilometers are packed with thrills and unbelievable views. Trust me, you'll want to stop and snap a ton of photos. And keep an eye out for wildlife! You might spot tracks from wild boar, foxes, beech martens, or even wildcats. It’s an incredible, unforgettable experience. Get ready for a road trip you won't soon forget!

Crossing the scenic Puente del Embalse de la Peñamoderate

Crossing the scenic Puente del Embalse de la Peña

🇪🇸 Spain

# Puente del Embalse de la Peña Okay, so picture this: you're cruising through Aragon in northeastern Spain, and you stumble upon one of those bridges that makes you actually pull over to soak it all in. Welcome to Puente del Embalse de la Peña. This stunning iron bridge stretches nearly 192 meters (that's about 630 feet) across the shimmering Peña reservoir, and it's honestly one of those views that reminds you why road trips exist. Built way back in 1913, this beauty connects the sleepy villages of Santa María de la Peña and Murillo de Gállego via the A-132 road. Here's the thing though—this isn't your typical highway bridge. It's narrow. Like, *really* narrow. Only one vehicle can cross at a time, so if you meet someone coming the other way, someone's backing up. But that's half the charm, right? It forces you to slow down and actually appreciate where you are. And the scenery? Absolutely unreal. You're basically driving through the Pre-Pyrenees with this dramatic mountain landscape sprawling out in every direction. The road is paved and well-maintained, but that single-lane setup means you need to stay alert and take your time. This is the kind of drive that ends up in your travel diary as one of those unforgettable moments—where engineering meets nature in the most spectacular way possible.

Driving the Exciting ER338 Road in Serra da Estrelamoderate

Driving the Exciting ER338 Road in Serra da Estrela

🇵🇹 Portugal

Get ready for a thrill ride! High up in Portugal's Serra da Estrela mountains, in the Guarda district, awaits the incredible ER338. This paved beauty winds for 28.1 kilometers (about 17.5 miles) between Col de Zezere and Manteigas, promising breathtaking scenery. Keep an eye out, though – this stunning road can close without warning. Landslides, especially after storms or fires, are a real possibility thanks to the unstable mountain terrain. And, of course, winter snowfall can shut it down completely. You'll spot signs reminding you to "Test Your Brakes" and "Use Low Gears," hinting at the road's steepness – some sections hit a maximum gradient of 10%! But the views? Absolutely worth it! There are plenty of viewpoints to soak in the panorama. Plus, you'll be driving along the Zêzere glacier valley, a prime example of how glaciers shaped this landscape. This valley, the largest of the Estrela glacial valleys, stretches for around eight kilometers and boasts a classic U-shape carved by the ice age. Word of warning: this isn't a route for big rigs. The middle part gets super narrow, turning into a single lane in spots due to those pesky rockfall risks. Pro tip: Before you go, double-check if the road is open! With the potential for closures after storms, fires, and winter weather, knowing the conditions is crucial for a safe and unforgettable adventure.

Seostik

🌍 Montenegro

Okay, adventure junkies, listen up! You HAVE to experience the Seostik Pass in Montenegro. Seriously, this mountain road, also known as the M2.3, climbs from the bustling coast near Budva all the way up to 876m (2,874ft). Starting near Budva, with its crazy-popular beaches and nightlife, the climb stretches for 17.3 km and gains a whopping 873m in elevation. That's an average gradient of 5.04%, so hold on tight! The pavement is decent, but this route is STEEP! Plus, it’s part of the stunning Budva Riviera, so expect major drop-offs and enough hairpin turns to make you question your life choices (in a good way!). Trust me, the views are worth it. Think panoramic shots of Budva's Old Town, the islands of St. Nicholas and St. Stephen, and the whole Riviera spread out beneath you. Seriously, pack your camera, charge those batteries, and clear some memory space – you’re going to need it! This drive is unforgettable.
