Cruising through western Sichuan Province, China? Buckle up for the Cho La Mountain Tunnel, a mind-blowing shortcut through the Cho La Mountains! This beast of a tunnel sits at a staggering 4,378m (14,363ft) above sea level.
Opened in 2017 after a 15-year build, this 7km tunnel (plus 5km of access roads) is part of the G317 highway, linking Chengdu to Nagqu in Tibet. Imagine the challenge of building something like this at such an altitude, where the air is thin and the temperatures plummet!
The tunnel, also known as Que'ershan Tunnel, cuts through the mountains between 4,232m and 4,378m above sea level. The tunnel is paved, speed is limited to 40 kph, and it takes around 10 minutes to cross.
Before this tunnel existed, drivers faced a harrowing journey over a treacherous mountain road, dodging landslides, avalanches, and all sorts of nasty weather on the Que'ershan Mountain Pass at 4,920m (16,141ft)! This tunnel slices two hours off the trip and bypasses the scariest parts of the old road. Trust me, you'll be grateful for this engineering marvel when you see the views!

extremeWhere is Mianah Pass?
🌍 Afghanistan
Okay, buckle up, adventure junkies! We're heading deep into the heart of Afghanistan's Bamyan Province, to tackle the legendary Mianah Pass (Kotal-e Mianah). Think hardcore. This isn't your Sunday drive; it's a serious expedition across the Hindu Kush mountains. Picture this: you're smack-dab in the Bande Pitaw Wildlife Refuge, surrounded by massive valleys and jagged, rocky peaks. It's stunning, raw, and seriously isolated. This road – and I use that term loosely – follows ancient paths, untouched by modern upgrades for decades. We're talking total wilderness vibes. The route itself is a 121 km (75 miles) north-south beast, linking Nargis and Nowjok. Forget smooth tarmac; this is a relentless gauntlet of deep potholes, brutally steep climbs, and narrow, exposed ledges that will test your nerve. Hairpin turns? You'll be dizzy from them! Plan for several days to conquer this stretch – help is virtually non-existent, so you're on your own. Now for the reality check: Afghanistan comes with significant security concerns. The threat of conflict is real, especially in remote areas like this. Emergency services? Fuel stations? Medical help? Don't even think about it. If you absolutely HAVE to travel this route, do it in a convoy and be hyper-vigilant. Vehicle-wise, a seriously prepped 4x4 is non-negotiable. High clearance, low-range gearing, the works. The altitude (we're talking over 3,500m/11,500ft) will sap your engine's power, so make sure your cooling system is top-notch. Pack extra fuel (enough for at least 300 km/186 miles), multiple spare tires, heavy-duty recovery gear, and a comprehensive first-aid kit. You'll be glad you did. And a final word: winter is a NO-GO. Heavy snows shut this pass down completely from late October to at least May. Spring thaw? Think mud, treacherous snowmelt streams, and more danger. The sweet spot is summer, but even then, be aware of potential flash floods. This road is not for the faint of heart, but the scenery? Unforgettable.
hardA Road of Contrasts: Where is Almass Pass?
🇮🇷 Iran
Okay, picture this: the Almass Pass, snaking its way high into the mountains of northwestern Iran. It's like the star of the show on the Asalem to Khalkhal Road – arguably the most stunning drive in the whole country! This 66km (41 mile) stretch of Road 319 connects the super green Gilan forests to the rough and tumble Ardabil mountains. We're talking about a crazy transition, people! You start at sea level, practically swimming in a humid, jungle vibe, and bam! Less than an hour later, you're in an alpine wonderland. Now, is it a breeze? Nope. Even though it's paved, this road throws a lot at you. Think endless hairpin turns and seriously steep climbs. And here's the kicker: the Caspian Sea loves to blanket the road in a thick fog, so sometimes you can barely see your hand in front of your face. If you get carsick easily, pack some ginger! Pro tip: fill 'er up! There's no gas for like 80 kilometers between the towns on either side, so don't be caught short. And when it comes to places to crash, skip the fancy hotels. Instead, look for the cozy local inns and wooden cabins, especially near the top. Trust me, it's way more authentic. Keep in mind that this area of the Talesh Mountains gets hammered in winter. Snow can shut things down, and avalanches are a real risk. Even in late spring, the weather can be totally different at the top compared to the valley floor. Pack layers! You might be freezing at the summit while it feels like summer down below.
hardWhere is Burzil Pass?
🇵🇰 Pakistan
Okay, adventure seekers, listen up! I've got a pass for you that's seriously going to blow your mind. We're talking about Burzil Pass, chilling way up in the Himalayas in Pakistan's Gilgit-Baltistan territory. We're talking 4,210m (13,812ft) above sea level, so buckle up for some serious altitude. You'll find it north of the Line of Control, about 30km, near Gilgit. The road is paved, but don’t think it’s a cakewalk! This historic caravan route linking Srinagar and Gilgit will put your driving skills to the test with some seriously steep sections – we're talking gradients up to 11%! The adventure kicks off near the exciting , and from there it’s a 115km (71-mile) ride to the top. But here's the catch: this road is ONLY open from July to September, thanks to the crazy amounts of snow it gets. But trust me, it's worth the wait! You'll be rewarded with incredible views of grassy slopes absolutely bursting with wildflowers. Seriously, a feast for the eyes!
extremeIs the road to Zong Co Lake in Tibet unpaved?
🇨🇳 China
Okay, adventure seekers, buckle up for Zong Co Lake in Tibet! This isn't your average Sunday drive. We're talking about a glacial lake shimmering at a staggering 16,325 feet! You'll find it nestled in Dinggyê County, part of Xigazê city. Forget smooth asphalt; this 11.5-mile stretch from Zhaxigang Village is all about embracing the ruggedness. Expect a completely unpaved road that will test your driving skills! Think narrow passages, seriously steep climbs, and hairpin turns galore—count 'em, eleven of them! Word to the wise: This route isn't for the faint of heart (or those prone to altitude sickness). The air is thin up here, so acclimatize before you go. And definitely bring your trusty 4x4; you'll need it! Oh, and a heads up – Mother Nature calls the shots here. This road is usually buried in snow from late October until sometime between late June and early July, so plan accordingly. But trust me, if you're after a truly unforgettable experience with views that will blow your mind, Zong Co Lake is calling your name.
