# The Epic Drive Up Mauna Loa
Want to experience something truly otherworldly? Head to Hawai'i and tackle the Mauna Loa Scenic Drive—a wild 17-mile journey up one of the country's highest paved roads. Starting from Saddle Road at 2,001m, you'll climb 1,401 meters of elevation through a genuinely alien landscape of solidified lava to reach Mauna Loa Observatory at 3,402m (11,161ft).
Built back in the 1950s, this narrow asphalt ribbon cuts through volcanic terrain that looks like the moon. "Mauna Loa" means "Long Mountain" in Hawaiian, and you'll understand why as you wind upward with an average 4.98% gradient. The road's rough, patchy surface features a white fog line down the middle—straddle it to avoid your tires on the jagged lava rocks lining the narrow shoulders.
Fair warning: don't attempt this if you have heart or respiratory issues. The road gets serious about hazards with warning signs everywhere, and for good reason. It's basically a single lane with blind hills, tight turns, and zero forgiveness if visibility drops. Fill your gas tank before you go—there's nothing at the observatory.
The rewards, though? On crystal-clear days, the views are absolutely stunning. You'll spot Mauna Kea, Kohala, Haleakala on Maui, and sometimes even other islands in the distance. The drive winds through Hawai'i Volcanoes National Park with plenty of pullouts to stretch your legs and soak it in.
Here's the catch: weather can turn on a dime. Fog, clouds, snow, rain, and whiteouts are all possibilities year-round. If conditions start deteriorating, bail out immediately—this road is genuinely dangerous in poor visibility. Winter can bring blizzards and high winds, temperatures drop below freezing at night always, and remember, this is an active volcano (last erupted in 1984). Most of the road is drivable in any 2WD vehicle, but plan your visit for the clearest day possible and respect this mountain's power.

moderateWhere is Last Dollar Pass?
🇺🇸 Usa
Okay, picture this: Last Dollar Pass, perched way up in Colorado's San Miguel County at a whopping 10,676 feet! Everyone raves about it being one of the state's best backcountry drives, and I'm here to tell you why. We're talking southwestern Colorado, folks. This isn't your average highway; it's an old mining supply route from the 1800s that's been transformed into a seriously scenic dirt road (aka Last Dollar Road #638). Now, about the road itself: It's unpaved the whole way. In dry weather, most cars can handle it, but after it rains, things get muddy, and 4WD is your friend. Really though, a high-clearance 4x4 is the ideal ride. It's about 22 miles long, winding from CO-62 to CO-145. It’ll take you two or three hours because you'll be going slow and stopping for pictures every five minutes. Think of it as the super-scenic shortcut between Ridgway and Telluride. Heads up: this road is only usually open from June to September when it's dry because winter shuts it down completely. So, plan your trip accordingly and definitely don’t go if the weather looks iffy. Why bother? Oh, the views! Around every corner are those classic Colorado vistas. The Wilson Range, St. Sophia Ridge, Palmyra Peak, and the Sneffels Range all put on a show. Seriously, it might just be the best spot to catch the fall colors, with aspen groves for days. Wildflowers explode in early summer, and keep your eyes peeled for deer, elk, and even bears roaming around. Oh, and fun fact, John Wayne's "True Grit" filmed its opening and closing scenes here. Talk about a legendary backdrop!
moderateRobertson Road is one of America's Creepiest Roads
🇺🇸 Usa
Okay, thrill-seekers, buckle up for a spooky ride down Robertson Road, aka Old Ghost Road (Bulloch County Road 403), right outside Statesboro in eastern Georgia! This isn't your average Sunday drive; it's said to be one of America's creepiest roads! We're talking about a short, gravelly stretch – just 0.9 miles long – that connects Railroad Bed Road to US-80. Picture this: you, a dirt road, and nothing but thick woods and trees all around, with very few houses to be seen. But here's the juicy part. Legend has it that this place is seriously haunted. People whisper about seeing unexplained lights, especially an eerie orange glow followed by a ghostly figure digging a ditch – a man who lost his head to a train, some say! Supposedly, he'll even start walking towards your car before vanishing into thin air. And if that isn't enough to send shivers down your spine, keep an eye out for spectral dogs roaming the area. There's even a nearby cemetery where, if you're brave (or foolish) enough to wander, you might hear these phantom pups trying to dig up their owner's graves! So, if you're into ghost stories and haunted places, Robertson Road is a must-see… if you dare.
extremeThrilling Adventure on Waipio Valley Road in Hawaii: The Steepest Road in the USA
🇺🇸 Usa
# Waipio Valley Road: Hawaii's Most Insane Descent If you're hunting for one of the most intense driving experiences in America, look no further than Waipio Valley Road on the Big Island of Hawaii. This legendary 2.25 km (1.4-mile) stretch is basically the holy grail for adrenaline junkies—and it might just be the steepest road of its length anywhere in the US. Tucked away in the Hamakua District on the island's northeast coast, this paved road drops from 279 meters down to just 7 meters above sea level, plunging into the stunning Waipio Valley (whose name means "curved water" in Hawaiian). We're talking about grades that reach a jaw-dropping 40-45% in sections, with an average of 25%. To put that in perspective, this road is actually steeper than famous steep streets like Baldwin Street in New Zealand or Canton Avenue in Pittsburgh. Here's the thing: **you need a serious 4x4 to even attempt this.** Rental car companies actually prohibit it, and for good reason. The road is so steep that regular brakes will literally fail on the way down—vehicles must descend in first gear, low range, to avoid catastrophic brake failure. Non-4x4 vehicles have been fatal on this road, and if you somehow make it down in a regular car, good luck getting it back out without dropping thousands on a tow truck. The etiquette here is pretty cool though: at the rare wider spots on this narrow, winding road, downhill traffic yields to uphill traffic. And if hiking is more your speed, the road makes for an epic walk with incredible valley views. **Important note:** As of February 2022, the road was closed indefinitely due to deteriorating conditions and safety concerns, though locals have been fighting to reopen it. Currently, only residents and agricultural leaseholders are allowed access. If you're keen to explore Waipio Valley, organized tours are your best bet—or lace up your hiking boots and experience it on foot.
easyScenic Byway 163 is where Forrest Gump stopped running
🇺🇸 Usa
Okay, buckle up for an epic road trip on Scenic Byway 163! This fully paved, 65.8-mile stretch is a wild ride from the Arizona border, near Kayenta, up through Utah to US 191, close to Bluff. Give yourself around 3 hours to soak it all in, but trust me, you'll want to budget extra time for those Insta-worthy photo ops and side adventures! Built back in 1970, this road climbs to 5,711 feet above sea level and carves right through the iconic Monument Valley. Think classic Old West desert landscapes and towering red rock formations – seriously, the views are insane! Just watch out for tourists who get a little too excited and wander into the road for that perfect shot. Speaking of excitement, this highway has it all: elevation changes, hairpin curves, twisty "S" curves, and long, sweeping bends. While it’s a fantastic drive, maybe skip it in the peak of summer when temps can hit 100°F. Oh, and did I mention this road is practically a movie star? Nicknamed the "Forrest Gump Road", it's been featured in tons of films (think *Easy Rider* and *Forrest Gump*) and commercials. It's a total Wild West dreamscape, the kind of place where classic westerns were born. Get ready to feel like you've stepped back in time!
