Year-round
Okay, picture this: you're on the Big Island of Hawai’i, ready for an adventure up the slopes of Mauna Loa, a massive active volcano. The road you're about to tackle? Mauna Loa Scenic Drive, also known as Mauna Loa Observatory Road. It’s about 17 miles of narrow, paved road carving its way through a seriously otherworldly lunar landscape made of solidified lava.
"Mauna Loa" means "Long Mountain" in Hawaiian, and this road lives up to the name! Built in the 1950s, it climbs from around 6,500 feet to over 11,000 feet, all the way to the Mauna Loa Observatory, a super important research facility studying climate change.
The road is steep, gaining over 4,600 feet in elevation – that's an average gradient of almost 5%. A 2WD vehicle can handle it, but be ready for some rough patches and potholes, especially at the beginning. Keep an eye out for that thin white "fog line" down the middle – it's your guide when the clouds roll in. The pavement can be barely wider than a car, and the shoulder is basically jagged lava rock, so straddle that line whenever you can to protect your tires.
This road can be hazardous, with blind hills and turns. Go slow, be careful around corners, and fill up your gas tank before you go – there are no services at the top!
The views are worth it, though! On a clear day, you’ll see Mauna Kea, Kohala, Haleakala (on Maui!), Hualalai, and the saddle at Pohakuloa. You might even spot other islands!
But a word of caution: weather changes fast up here. If fog or clouds start to roll in, bail immediately! This road is NOT where you want to be in low visibility. Winter can bring blizzards, high winds, and whiteouts – snow is possible any time of year. High-altitude storms can pop up without warning. And remember, Mauna Loa is an active volcano, with the most recent eruption occurring in 1984. Volcanic eruptions are possible at any time. Be smart, be prepared, and enjoy the ride!

hardWoodchuck Pass
🇺🇸 Usa
Alright, thrill-seekers, let's talk Woodchuck Pass! This beast sits way up in Sheridan County, Wyoming, clocking in at a cool 9,636 feet above sea level. Forget your sedan, you'll need a 4x4 to tackle Forest Road 226. It's a gravel road, and not exactly smooth sailing. Think rocky terrain, seriously steep inclines, and a handful of creek crossings (we're talking ankle-deep, but one's so murky you won't see the bottom!). Oh, and did I mention the gates? You'll need to hop out and open (and close!) three of them along the way. Given its elevation, snow can shut this beauty down without warning, so check conditions before you go. But trust me, the views are worth the adventure.
extremeWhere is Elephant Hill Road?
🇺🇸 Usa
Okay, so you're up for a challenge? Then you NEED to check out Elephant Hill in Utah's Canyonlands National Park! Nestled between Moab and Monticello in San Juan County, this 9-mile dirt track is legendary for being one of the trickiest 4x4 routes around. Picture this: Seriously steep climbs, boulders galore, nerve-wracking drops, hairpin turns that'll have you backing up, and views that will absolutely knock your socks off. This isn’t a Sunday drive, folks! You'll need a high-clearance 4x4 with low range – leave the family SUV at home. And keep your vehicle under 21 feet long. Allow around 4-5 hours to conquer it without stopping. Elephant Hill is generally open year-round, but be warned, it's a desert environment. Summers are scorching and winters can get chilly. Pack tons of water, and hit the trail early to beat the heat and the crowds. Built in the 40s, this trail will test your skills and reward you with scenery you won't find anywhere else! Just don't go it alone!
moderateHow long is the road to La Joya hut?
🇲🇽 Mexico
Nestled in the heart of Izta-Popo Zoquiapan National Park, in the State of Mexico, lies La Joya, a mountain hut soaring at 3,977m (13,047ft). This dirt road stretches 7.1km (4.41 miles), kicking off at 3,692m (12,112ft). Be prepared for some steep climbs — you'll encounter gradients hitting 9% along the way. Although it's open to all vehicles, you'll want a high-clearance, 4-wheel-drive vehicle to conquer it! The road gets a bit gnarly near the end, so many park a bit before La Joya to avoid the rough cobblestone hill. Don't miss the side trip to La Joyita, a minor road that climbs even higher to 4,009m (13,152ft). Just remember, the road is only open from 8 AM to 6 PM. Near the hut, you'll find a parking lot, perfectly situated for those heading to the Iztaccíhuatl volcano.
hardWhy is Cerro de la Cúpula famous for?
🇲🇽 Mexico
Okay, fellow adventurers, picture this: You're cruising from Ensenada, Mexico, into the heart of Baja California, and aiming for the sky. Literally! You're headed for Cerro de la Cúpula, a killer peak soaring to a mighty 9,206 feet. This isn't just any mountain. Perched at the top, inside the Sierra de San Pedro Mártir National Park, is the National Astronomical Observatory. Open for tours weekdays 10am-1pm, this is a must-see. We're talking about one of the top stargazing spots *in the world*. Forget light pollution – the views here are insane, so bring your camera! The road itself? It’s paved the whole 62 miles from Ensenada, but get ready for some steep climbs! Weather can be a real mood-killer, so keep an eye on the forecast. We’re talking snowstorms in winter (yes, snow!), and scorching desert heat in summer at lower elevations. Pack layers! This place is stunning, with views that stretch forever, but Mother Nature calls the shots.
