Year-round
Nestled between Banyuwangi and Bondowoso in East Java, Indonesia, Mount Ijen is home to the stunning turquoise crater lake, Kawah Ijen (Ijen Crater).
The adventure to this incredibly acidic lake, famed for its sulfur deposits, starts above the Ijen Plateau. The 3.2 km (2 mile) unpaved road begins at Pos Perijinan Kawah Ijen, the starting point before you ascend. It's a bumpy ride to the trailhead, followed by a 1.5-hour hike, including some pretty steep sections. Once you reach the crater rim, you'll likely see miners carrying heavy baskets of sulfur. The lake itself is a reservoir of sulfur, where it's mined daily. Watch out for the miners carrying incredible loads (75-90 kg!) up the trail. This sulfur mining has been going on since 1968.
The acid lake here is the world's largest! This volcano is famous for its electric blue fire, acidic crater lake, and the grueling sulfur mining. This sulfur, nicknamed "Devil's Gold," gets its name from its yellow color and the dangerous conditions. The water is so acidic it can dissolve flesh, clothes, even metal! Seriously, within 15 seconds, it can start to decompose human skin. Swimming? Definitely not recommended. You can descend into the crater, but be quick and at your own risk. Masks are crucial to avoid inhaling those toxic fumes. It's incredibly hot, smells awful, and the air is terrible, making a long stay pretty much impossible. Don't touch anything, and definitely don't touch your face. In 2018, the crater was closed for months because of toxic gas emissions, evacuating hundreds of locals.
The road is super narrow and incredibly steep, making a 4x4 absolutely necessary. No private vehicles are allowed.
In recent years, Kawah Ijen has become a popular tourist spot. One of the big draws is the "blue fire," one of the only places on Earth you can see this phenomenon. When sulfuric gases meet high temperatures, the sulfur ignites, creating blue flames. You can only see these flames at night, though they burn 24/7. Temperatures can reach a scorching 600˚C (1112°F), but the blue flames are only visible at night. Sulfur ignites at 360˚C (680°F), but a chemical reaction causes the blue hue, not the temperature.

extremeUmling La is the highest paved road on Earth
🇮🇳 India
# Umling La: The Ultimate High-Altitude Adventure Ready for one of the most extreme drives on the planet? Umling La sits at a jaw-dropping 5,818m (19,087ft) above sea level in Ladakh, Jammu and Kashmir, making it one of the world's highest motorable passes. This 52km stretch connecting Chisumle to Demchok villages hugs the ridgeline between Koyul Lungpa and the Indus River, just 230km from Leh. ## A Road Built for Strategy This engineering marvel was completed in 2017 as part of Project Himank, designed to connect the remote Demchok zone and support military operations along the sensitive Indo-Chinese border. The Border Roads Organization pulled off something incredible here—paving a full road through some of Earth's most hostile conditions. We're talking temperatures that plummet to -40°C and oxygen levels that sit at roughly half of what you'd breathe at sea level. Honestly, it's mind-blowing stuff. ## The Reality Check Buckle up: this isn't a casual Sunday drive. Altitude Mountain Sickness (AMS) is real, and the risks escalate to pulmonary and cerebral edema at this elevation. Breathing becomes genuinely difficult. If you've got respiratory issues or heart conditions, skip it. Everyone else? Acclimate properly, pack supplementary oxygen, and get checked out beforehand. The scenery is brutally gorgeous—endless barren terrain with zero signs of civilization. Wind whips at you from multiple directions simultaneously, and winter conditions make the road impassable from late October through June or July. ## Before You Go You'll need permits from the Leh District Commissioner's office since this is a restricted military zone near the LAC. Check current conditions before heading out, and remember: there's a tiny bar-cafe at the summit if you make it!
moderateHow to drive to Wenquan, one of Earth's highest road-accessible towns?
🇨🇳 China
Okay, adventure junkies, listen up! We're heading to Wenquan, China, a ridiculously high mountain town chilling at a staggering 16,732 feet (5,100m) above sea level in the Qinghai province. Seriously, it's one of the highest towns you can actually *drive* to on planet Earth! Nestled in the Tanggula Mountains, just north of the legendary Tanggula Pass, Wenquan (also known as Wenchuan or Wenzhuan) offers views that'll make your jaw drop. While it might be famous for its altitude, keep in mind there are even higher villages dotted around the globe. The area is teeming with wildlife including snow leopards and panda! The Qinghai-Tibet Highway (part of China National Highway 109) is your paved path to this high-altitude haven. This epic 398-mile (642km) stretch runs from Nagqu in Tibet all the way up to Budongquan. Word of warning, though: being in the Tibetan Plateau means the weather is totally unpredictable, swinging from sunny skies to sudden snowstorms in a heartbeat. Plus, the altitude is no joke! The thin air can make even simple activities a real challenge, so be prepared for potentially severe altitude sickness. But hey, the incredible views and bragging rights are totally worth it, right?
extremeWhere is Thorong La?
🇳🇵 Nepal
Okay, picture this: you're trekking the legendary Annapurna Circuit in Nepal, and you're about to hit Thorong La Pass, one of the highest and most famous passes around! Now, getting to the top isn't exactly a Sunday drive. We're talking a seriously gnarly, unpaved 4WD track way up there. Word is, someone who experienced a bit of drama at the pass donated a chunk of change to build it, hoping it'd speed up rescues. The road stretches quite a distance. Near the very top, expect some seriously steep inclines! Beyond that, it might get too wild even for your trusty 4x4. Seriously, timing is everything. If you want to soak in those incredible Annapurna views without the drama, aim for crossing during the safest months. Trying your luck any other time? You're looking at a way higher risk of avalanches, frostbite, and potentially getting stuck in a storm or whiteout. Acclimatization is crucial!
hardHow to get to Komic in India, one of the highest towns accessible by car on Earth?
🇮🇳 India
Hey fellow adventurers! Have you heard of Komic? This remote village sits way up high in the Indian Himalayas, in the Lahaul and Spiti district of Himachal Pradesh, clocking in at a dizzying 4,572 meters (15,049 feet)! Komic gets a lot of buzz as the "highest village in the world connected by a motorable road," but while it might not wear that particular crown, it IS the highest village in India and boasts the world's highest permanent post office. Pretty cool, right? Getting there is an adventure in itself. The 17 km (10.56 miles) road from Kaza, off the Spiti Valley Road (Road 505), is now paved, making it easier to reach. Don't let that fool you though! You'll be tackling 25 hairpin bends, navigating narrow sections, and white-knuckling it past some seriously steep drop-offs. But trust me, the views are SO worth it! Think snow-capped peaks, stunning valleys, and an experience you won't soon forget. Just be aware that due to heavy snowfall, Komic is often cut off from the world for half the year. So plan accordingly!
