Hey adventurers, get ready to cross the Cho La Mountain Tunnel in western Sichuan, China! This high-altitude passage cuts through the Cho La Mountains at a whopping 4,378m (14,363ft) above sea level, connecting Chengdu to Nagqu on the G317 highway.
It's no quick jaunt – this 7km tunnel with its 5km of access roads, takes about 10 minutes at a leisurely 40 kph. But trust me, it's worth it.
Before this tunnel opened in 2017, drivers faced a harrowing climb over the Chola Shan Pass at 4,920m (16,141ft), battling landslides, avalanches, and treacherous ice. Now, you can bypass that crazy section and save a solid 2 hours! The scenery is breathtaking, but remember the altitude can make things challenging. Prepare for thin air and chilly temps!

extremeThe rugged road to Dza La: a high mountain drive in Qinghai province
🇨🇳 China
Okay, adventure junkies, listen up! Let me tell you about Dza La, a wild mountain pass chilling at a whopping 4,690 meters (that's 15,384 feet!) in Qinghai Province, China. You'll find it tucked away in Yushu City County. Now, this isn't your average Sunday drive. This 11.7 km (7.27 mile) stretch, also called Chumarleb or Qumalai, is a totally unpaved beast! Think narrow, steep, and edges that drop off into oblivion. Seriously, this road demands respect. Heads up: because this route is so remote and, let's face it, a bit hairy, they built a tunnel as part of the G215. So, if you're just trying to get from Yushu to Longbaozhen, take the paved road. But for the true thrill-seekers? Dza La awaits.
hardWhere is Terkhiin Tsagaan Lake?
🌍 Mongolia
Okay, picture this: Terkhiin Tsagaan Lake – a shimmering "White Lake" way up high in central Mongolia's Terkhiin Tsagaan Nuur National Park. Seriously, we're talking some altitude here! Is it worth the trek? Absolutely. Imagine this: the lake is sparkling against a stunning vista of pine-covered lava fields. Legend says the lake was made when an old couple forgot to cap a well, flooding the valley until a hero capped it with a mountaintop! Now, the road in? It's roughly entirely long, and goes east to west. Just remember the Khovd River bridge isn't easy, so get ready for an adventure.
extremeHow long is the road through Chun La?
🇨🇳 China
Get ready for Chun La, a seriously epic mountain pass in Tibet's Nyingchi Prefecture! Part of the legendary Chacha Highway (aka the Bingchacha Line), this is raw, untamed overland travel at its finest – think Yunnan to southeastern Tibet, but way more hardcore. We're talking pure, unadulterated off-road, stretching between Murub and Kaidag. Forget pavement, this is mud, scree, and maybe a little quicksand thrown in for good measure. Maintenance? Non-existent. The real test comes with a 14 km stretch packed with 23 hairpin turns that’ll make your head spin. The road's basically carved into the side of unstable slopes, so expect a constantly shifting track with deep ruts and the occasional boulder surprise from above. Think you can tackle Chun La in winter? Think again! Perpetual snow patches and crazy high-altitude ice mean it’s a seriously dicey proposition. Even in summer, a rogue storm can turn those steep climbs into a muddy nightmare. Tire chains and recovery gear are absolute musts. So, what's the worst that can happen? Geological instability and thin air, my friends. Sections of “rolling stone” slopes can turn into a trap after it rains, and those cliffs are long, unprotected, and the road is often just wide enough for one vehicle. Oh, and at 4,500 meters, your engine's gonna lose about 30% of its power, making those steep, muddy hairpins a real challenge. Keep your eyes peeled for falling rocks – they're everywhere after seismic activity or bad weather. Heads up: you're on your own out here. There's zero fuel, repair shops, or medical help between Murub and Kaidag. Pack at least two spare tires, a high-lift jack, and seriously consider rolling with a convoy of at least two vehicles. And make sure your cooling system is in top shape because that sustained low-gear climb will put it to the ultimate test.
moderateDriving a military road to the summit of Qandil Mountain
🇮🇷 Iran
Okay, adventure junkies, listen up! Ever heard of Qandil Mountain? This bad boy sits right on the Iran-Iraq border, clocking in at a hefty 11,190 feet. A new road – and I use that term loosely – winds its way to the top, built by the Iranian army. This isn't your Sunday drive, folks. We're talking completely unpaved, rough and ready terrain connecting West Azerbaijan in Iran to the Kurdistan Region of Iraq. Now, here's the serious bit: this area is considered unsafe. Word on the street is there's a landmine risk on the way up. Plus, this region is seriously off the beaten path. You're basically right on the border between two countries, and there are whispers of military outposts dotted around. Stunning views? Probably. A relaxing road trip? Definitely not. Tread carefully, my friends.
