Just outside of Istanbul, Turkey, you'll find the Çatalca Tunnels, a pair of totally cool highway tunnels that made history!
Where? They're smack-dab in Istanbul Province, in a central spot within the Marmara Region, on the eastern side of Turkey.
These tunnels are completely paved and part of the Otoyol 7 (O-7) motorway, also called the Northern Marmara Highway. One tunnel is 549 meters (1,801 ft) long, and the other is 511 meters (1,677 ft). The toll highway itself is a whopping 243 km long between the Kınalı and Akyazı junctions, boasting eight lanes and bypassing Istanbul to the north.
These tunnels are famous because an Italian pilot named Dario Costa completed a crazy feat: flying an airplane through *two* tunnels!
Nobody had *ever* done that before. This was a complicated challenge he dreamed of for years, but he totally nailed it. It took him just 43.44 seconds, hitting average speeds of 245 kph and a top speed of 303.08 km/h (188.07 mph) in the second tunnel.
The flight was just 2.26 km, but it required insane precision, starting in one tunnel, going through a short stretch of open highway, and then diving into the second tunnel.
Over a year of prep and 40+ people went into making this record-breaking flight a reality!
The most critical moment? When Costa had to navigate the plane through a 360m gap between the tunnels, battling crosswinds. He totally crushed it and even did a loop afterwards!

moderateWhat’s the history of Old Tragjas?
🇦🇱 Albania
Old Tragjas, Albania is an eerie, ruined village with a powerful story. This town was abandoned after being bombed in 1943 because of partisan sympathies, so tread carefully among the ruins. Old Tragjas played a key role in Albanian history as the site of a battle where Albanian resistance fighters took down Italian troops. The village was bombed in 1943 due to its anti-fascist ties and has been deserted ever since. You'll find these ruins nestled on hills overlooking the Bay of Vlora, about 25 km from the city of Vlora. It was named a cultural monument in 1980 for its architecture – a classic representation of the region's cultural roots. Historians believe that Gjergj Arianiti, Donika Kastrioti’s father, founded the settlement around the turn of the 15th century. The mountain village has a fantastic location for both beauty and strategic reasons. Beautiful buildings with complex designs once stood here, blending into the landscape. However, three fires and WWII bombing runs left the village in ruins. Even after six decades, the village still holds secrets, with a long street and former homes. It’s a fascinating spot for history and architecture buffs. Artifacts found here hint at a long history dating back to ancient times. Now, about that road! Located in the south-western part of the country, the road to Old Tragjas is completely unpaved and treacherous, with lots of narrow sections. A 4x4 is usually best, but motorhomes should stay away. But the drive is visually rewarding! Starting from the new Tragjas village, the road is roughly 5.1 km (3.16 miles) long, climbing 263 meters with a 5.15% average grade. The road climbs to Qafa e Asters, named for the tombs scattered about. The pass offers views of ancient Orikum and the coast. Be careful and have a great trip!
moderateAn old military unpaved road to Sanson Pass in the Ligurian Alps
🇮🇹 Italy
# Sanson Pass: A Mountain Adventure Through Alpine History Ready for an unforgettable drive through the Alps? Sanson Pass sits pretty at 1,694 meters (5,557 feet) above sea level, straddling the France-Italy border in a seriously stunning corner of the world. Known locally as Colla di Sanson, Bassa di Sanson, or Baisse de Sanson, this 41.5 km (25.78 mile) gravel road connects the Alpes-Maritimes region of southeastern France with Liguria's Province of Imperia. This isn't your typical paved highway—it's a former military cart track that'll test your driving chops. The entire route is unpaved gravel, and conditions vary wildly depending on the season and recent weather. You'll need decent vehicle clearance and some genuine driving skills to tackle the rougher sections. The pass kicks off near La Brigue on France's D43 road and finishes near Molini di Triora on Italy's SP548. Along the way, you're basically time-traveling through pre-WWII history. The mountain pass is dotted with fascinating military relics—fortifications, small barracks, and old roads—all built when tensions ran high between France and Italy. But here's where it gets really cool: there are side routes worth exploring. Head toward Balcone di Marta and you'll discover an enormous fortress hidden beneath rolling meadows. Alternatively, veer off to the charming villages of Realdo and Verdeggia—picturesque shepherd settlements perched on the mountainside and part of Triora's commune. These ancient hamlets feel like stepping back centuries. Nestled in the Ligurian Alps, this gravel adventure delivers stunning mountain scenery mixed with layers of European history. Definitely one for travelers who want something beyond the standard tourist route.
moderateWhere is Popova Šapka?
🌍 Macedonia

The road to the summit, known as the R1209, is all paved and winds its way through the stunning Šar Mountains, a range that stretches across the Balkans. The journey starts in Tetovo, a city nestled at the foot of the Šar Mountain, bisected by the Pena River. From there, it's an 18km (11.18 miles) climb.

extremeWhere Is Col de Pause?
🇫🇷 France
Okay, so Col de Pause! This hidden gem is nestled in the French Pyrenees, right near the Spanish border. Think dramatic mountain scenery! Just be warned, you're going to be tackling the Route Forestière du Port d’Aula. This isn't your average Sunday drive. The road is narrow – seriously, two cars passing is a real challenge – and you'll be navigating hairpin after hairpin. It's said to be one of the trickiest drives in the Pyrenees. The whole climb is about , with a pretty significant elevation gain . The inclines can be pretty steep in sections. The views are definitely worth the effort!
