Year-round
Paso de Agua Negra (Black Water Pass) is an international high mountain pass at an elevation of 4.774m (15,662ft) above sea level, located on the border of Argentina and Chile. It's
one of the highest roads in the country
Where is Agua Negra Pass?
Set high in the Andes mountain range, the pass links the IV Region of Coquimbo (Chile) with the Province of San Juan (Argentina). It is the highest border crossing between Argentina and Chile, and the traffic is very low, with around 200 vehicles using it every year.
Can you drive to Agua Negra Pass?
Located in the central region of both countries,
the road to the summit is mostly unpaved. It’s called Ruta 41 (in Chile) and Ruta Nacional 150 (in Argentina). The pass is 318km (198 miles) long, running east-west from Las Flores (in San Juan Province of Argentina) to La Serena (the capital of the Coquimbo region on Chile’s coast).
The pass is driveable with any kind of vehicle. Opened in 1965, the pass was closed in 1977 due to political problems between the two countries and reopened to the public in 1994.
Is the Agua Negra pass open?
Because of its altitude, this pass is open only in summers (from December through April).
The rest of the year is blocked by snow. Remember to check before you drive, as the dates are dependent on snow conditions each year.
What’s Agua Negra tunnel?
A new tunnel (Agua Negra tunnel) is planned to bypass the mountain pass, allowing year-round traffic. The project consists of two parallel 13.9km (8.63 miles) tunnels, each comprised of two traffic lanes. The tunnels will have a maximum width of 11m, but because they run through high mountains, the maximum incline has been limited to 4%. The tunnel is expected to greatly improve economic connections between Chile, Argentina, Brazil, and Paraguay.

extremeA memorable road trip to Abra del Lizoite
🇦🇷 Argentina
Okay, adventure-seekers, buckle up for Abra del Lizoite, a seriously high mountain pass in Argentina, clocking in at a whopping 4,536m (14,882ft)! We're talking about one of the highest roads in the whole country, so prepare for some serious altitude. You'll find this beast nestled west of Abra Campana, right on the border between Jujuy and Salta provinces, up in northern Argentina near Bolivia. Think stunning, remote landscapes. Now, let's be real: the road to the top is a wild ride. It's entirely unpaved and seriously challenging, with more curves and hairpin turns than you can count. If you get carsick easily, maybe think twice! And definitely bring a high-clearance vehicle – you'll need it. This epic road is known as Ruta Provincial 5 (RP5) in Jujuy Province and Ruta Provincial 7 (RP7) in Salta Province. The whole thing stretches for about 78km (48 miles), running from Cajas (in Jujuy) to the seriously cool high-altitude town of Santa Victoria Oeste in Salta, which sits pretty at 2,400m above sea level. The scenery is absolutely worth the white-knuckle drive, trust me!
moderateAn awe-inspiring road to Mirador El Domo de La Culata
🌍 Venezuela
Okay, adventure junkies, listen up! I've found a hidden gem in Venezuela's Mérida State: Mirador El Domo de La Culata. Perched way up high in the Andes at a dizzying 4,291 meters (that's 14,078 feet!), it's one of the highest roads in the country, nestled within La Culata National Park. The road from Pico El Aguila (aka Collado del Condor) is a paved ribbon winding its way up for 7.2 kilometers (4.47 miles). Expect narrow stretches, hairpin turns, and a steady climb with an average gradient of 3.34% and an elevation gain of 241 meters. But trust me, the views are worth it! You'll be treated to some seriously stunning moorland scenery. Just be aware that snow can make an appearance between June and September. Get ready for an unforgettable Andean adventure!
hardWhere is Tequendama Falls?
🇨🇴 Colombia
Okay, so you're headed to Tequendama Falls in Colombia, just a hop, skip, and a jump from Bogotá? Buckle up for a quick but potentially wild ride! The paved road is only about 16 miles, running generally east-west from the main highway, but those curves are no joke – super tight and can be a bit treacherous, so keep your eyes on the road. The falls themselves are seriously impressive, plunging over 400 feet! But there's more than just water here. Check out the old Hotel del Salto – it's got a fascinating (and slightly dark) history. Perched right on the cliff edge, it once offered killer views, but sadly, it became a popular spot for... well, let's just say it has a *very* haunted vibe now. They've turned it into a museum, so you can explore the history (and maybe spot a ghost!). Legend has it the falls were created by Bochica, a Muisca deity who broke the ground with his staff. Whether you believe the legend or not, the scenery is stunning. Just remember to take it slow on those curves!
hardSalar de Uyuni Road
🇧🇴 Bolivia
# Driving Across Bolivia's Salar de Uyuni: A Once-in-a-Lifetime Experience Ready for a drive that'll mess with your head in the best way possible? The Salar de Uyuni is the world's largest salt flat, and it's absolutely mind-bending. We're talking 10,582 square kilometers of pure white nothingness sitting at 3,656 meters up in the Bolivian Altiplano, and there's literally nothing quite like it anywhere on the planet. Hit it during the dry season (May through November), and you'll be rolling straight across an endless white expanse of hexagonally cracked salt that stretches to every horizon. It's trippy—your brain genuinely struggles to comprehend the scale and emptiness surrounding you. But here's where it gets *really* wild: come back between December and April during the wet season, and the whole thing transforms into the world's largest natural mirror. A thin film of water covers everything, reflecting the sky so perfectly that you can't tell where earth ends and atmosphere begins. It's the kind of place that breaks Instagram. Most people start from the town of Uyuni and drive across to Isla Incahuasi—this rocky little island topped with massive cacti that juts out of the white plain like something from a fever dream. From there, the adventure usually continues into the Eduardo Avaroa National Reserve, where you'll encounter otherworldly colored lagoons, steaming geysers, and natural hot springs tucked into a volcanic landscape.
