This old toll road, County Road 070, connects Challis (off US Hwy 93) to Sunbeam (on ID State Hwy 75).
Clocking in at 8,809 feet (2,685m), this pass is a beast! Expect a mostly dirt and gravel road with some seriously narrow spots and grades hitting a maximum of 12%. Open from July to October, this route offers stunning views, but be warned: low-clearance vehicles and trailers might want to sit this one out. The road can get washboarded, making for a bumpy ride. Get ready for an unforgettable off-the-beaten-path experience!

# Mount Washington Auto Road: A Classic New England Adventure Ready for one of America's most iconic drives? The Mount Washington Auto Road is a wild 12-kilometer ride up New Hampshire's Presidential Range to the 1,917-meter summit—and trust me, it's an unforgettable experience. This gem has been drawing adventurers since 1861, when it first opened as a carriage road. That makes it one of the oldest tourist attractions in the US, and for good reason. The road doesn't mess around: you're looking at an average grade of 12% with some sections hitting a brutal 22%. By the time you reach the top, you'll have climbed over 1,400 meters of pure elevation gain. Here's where it gets wild: Mount Washington holds the world record for the highest wind speed ever directly measured on Earth—a bonkers 372 km/h recorded way back in April 1934. Even on supposedly "nice" summer days, you'll feel why this mountain demands respect. The real drama kicks in above the 1,200-meter mark, where you break through the treeline into the alpine zone. Conditions up here can flip in minutes—literally. But when the weather cooperates? The summit views are absolutely spectacular, stretching across four states, Quebec, and all the way to the Atlantic Ocean. This drive is equal parts adrenaline rush and scenic masterpiece.
moderateA scenic unpaved road to Buffalo Pass in Colorado
🇺🇸 Usa
Buffalo Pass, sitting pretty at 10,321 feet in Colorado, is a must-do if you're exploring the northern part of the state! You'll find it chilling on the Routt and Grand County line, nestled in the Routt National Forest between Steamboat Springs and Walden. This roughly 15-mile dirt road, known as Buffalo Pass Road (Routt County Road 38 and Forest Service Road 60), isn't too scary – most SUVs can handle it, and even some regular cars if you pick your lines carefully. The lower sections are usually fine for 2WD, but the last few miles get a little rough, so high clearance is your friend. Keep in mind this beauty is usually snowed in from December to late June/early July, so plan your trip accordingly! Speaking of weather, be prepared for anything! Sunshine can turn into a blizzard in minutes. Afternoon thunderstorms are common, so have an exit strategy. Sunscreen is a must at this altitude, and watch out for falling trees – they're not always polite enough to wait for the wind. Oh, and pack your bug spray – the mosquitoes are legendary! But it's all worth it! The views of the Yampa and North Park valleys are insane. Plus, you've got alpine lakes within walking distance, the Mount Zirkel Wilderness to explore, and plenty of campsites, including Summit Lake Campground. Summit Lake itself is super easy to get to from the top of the pass. Trust me, your Instagram will thank you!
extremeHow long is the Quebec Provincial Highway 389?
🇨🇦 Canada
Get ready for an epic Canadian adventure on Quebec Provincial Highway 389! This 567km (352 miles) route links Quebec to Newfoundland and Labrador, taking you from Baie-Comeau, nestled on the St. Lawrence River's north shore, all the way to Fermont. Now, a heads-up: this isn't your average Sunday drive. Expect a mix of surfaces, with sections of twisty, narrow asphalt giving way to stretches of gravel that can vary in quality. Driving conditions can change quickly. Snowstorms and blizzards can roll in, so be sure to check road conditions with the Quebec Ministry of Transportation before you go, especially in winter. Winter tires aren't just a suggestion; they're the law! Pack a winter emergency kit, just in case. R-389 takes you through seriously remote areas, so come prepared. Expect zero visibility on gravel parts. Gas stations are few and far between. Make sure your vehicle's in tip-top shape, and that you've got a spare tire and tools. Gravel roads can be tough on vehicles. Oh, and don't count on cell service – it's pretty much non-existent for most of the route. Keep an eye out for logging trucks, too. They're often empty heading north and they move fast. Pull over when it's safe to let them pass. Fuel up whenever you can, and maybe even bring an extra gas can, especially if you're heading further north. Pack plenty of food and water. The water you find along the way may not be potable. With a little preparation, Route 389 promises an unforgettable journey through the heart of Quebec's wilderness.
moderateHow long is Anton Anderson Memorial Tunnel?
🇺🇸 Usa
Okay, picture this: you're in Alaska, cruising along the scenic Portage Glacier Highway, and boom – you're about to enter the Anton Anderson Memorial Tunnel. This isn't your average tunnel; it's a whopping 2.5 miles long and a combined vehicle-railroad tunnel. Built back in the day, it's a true feat of engineering, connecting Whittier with the rest of the state. Heads up, traffic is controlled by a fancy computerized system, so you'll be alternating with trains and other vehicles. Inside, you'll see 1,800 texturized concrete panels and railroad tracks – yeah, it's a trip. Just remember, no hazardous materials allowed and convertibles need to keep their tops up. Tunnel hours vary each day of the week, but it's generally open from morning to late night, with shorter hours on Sundays. This tunnel is Whittier's lifeline, otherwise you're stuck taking a boat or train. The drive itself takes about 10 minutes, but factor in possible wait times. Safety first: there are huge ventilation systems to keep the air clean and emergency communication systems in case anything goes sideways. Sadly, no pedestrians or bikes allowed – it's strictly for cars and trains. Buckle up and enjoy this one-of-a-kind experience!
