Cruising through Colorado, you absolutely HAVE to experience the Eisenhower Tunnel! Straddling the border between Summit and Clear Creek counties, this engineering marvel punches right through the Continental Divide, about an hour west of Denver, inside the Arapaho National Forest.
Okay, so it's actually *two* tunnels: the Eisenhower Memorial Bore (completed in '73) and the Edwin C. Johnson Bore (finished in '79). Each one is about 1.7 miles long.
Why is it so special? At a whopping 11,158 feet above sea level, this is one of the highest vehicular tunnels on the planet. Sure, construction was a beast (seriously, it took years and cost lives), but now you get to shave off 9 miles compared to braving the hairpin turns of Loveland Pass on U.S. Highway 6!
The grade leading up to the tunnel is pretty steep, about 6-7%, so make sure your rig is ready for it. Oh, and heads up: HAZMAT vehicles have restrictions.
The drive only takes about 5 minutes, but experiencing this feat of engineering, and soaking in the surrounding Rocky Mountain views, is totally worth adding to your Colorado road trip itinerary. Just be prepared for company – around 10 million vehicles make the trek each year!

🇺🇸 Usa
Alright, adventure seekers, let's talk Robidoux Pass! Nestled on the western edge of Nebraska, inside Scotts Bluff National Monument and south of the North Platte Valley, this historic gem of a road tops out at 4,603 feet. Forget smooth sailing – Robidoux Road is a 19-mile stretch of pure, unadulterated dirt, connecting NE-92 to Summit Ranch Road. Don't worry, though, it's manageable for most cars.

🇺🇸 Usa
# Montana: Where Mountains Meet the Open Road Montana—the name says it all. Derived from the Spanish word for "mountainous," this sprawling Western state is basically nature's playground on steroids. You've got the wide-open Great Plains stretching across the east, and then BAM—the Rocky Mountains absolutely dominate the western half like some kind of geological mic drop. This is seriously untamed country. We're talking massive mountains, dramatic canyons carved by ancient rivers, lush forest valleys, and scenery that'll make your jaw hit the dashboard. The sheer scale of these soaring ranges—spread across a state bigger than many entire countries—means roads here do something pretty amazing: they carve through some genuinely remote, high-altitude passes that rank among America's most spectacular. If you're into driving experiences, Montana's highway network is basically a love letter to adventure seekers. These roads wind through some of the most breathtaking high-mountain terrain you'll find anywhere, offering the kind of vistas that make you understand why people fall in love with the open road. Ready to explore? There's a whole network of incredible routes waiting to be discovered, each one offering its own unique blend of challenge, beauty, and that special something you only get when you're driving through one of America's last great wilderness areas.
moderateWhere is Cumberland Pass?
🇺🇸 Usa
Okay, buckle up for a killer Colorado adventure! Cumberland Pass, clocking in at a whopping 12,040 feet above sea level, sits pretty in Gunnison County. Word on the street is, it’s one of the highest roads you can cruise in a regular car during the summer. You'll find this gem nestled in the heart of the Gunnison National Forest. Built way back in 1882 and spruced up a few times since, it's a historic ride! Cumberland Pass Road (County Road 765) stretches for about 15.8 miles, running from the quirky town of Tincup down to Pitkin. Now, about the road itself: it's unpaved but usually in pretty good shape. It can get a little bumpy and washboard-y in spots. Most cars can handle it, whether you've got 4WD or not. It's not crazy steep, but there are some narrow sections and drop-offs, so take it slow and enjoy the ride. Heads up: this pass is buried in snow most of the year, usually closed from late October to late June or early July. But is it worth it? Absolutely! This is a seriously scenic and historic drive. You'll wind through gorgeous pine forests, past old mine entrances (stay out!), and eventually pop above the treeline for jaw-dropping views. From the top, you can see over 50 miles of the Continental Divide. It's an unforgettable road trip!
easyWhy is it called Sherman Pass?
🇺🇸 Usa
Okay, road trip fans, listen up! Sherman Pass in Washington is calling your name. This isn't just any drive; it's a journey to 5,524 feet above sea level in the heart of Ferry County. And get this: it's the highest pass in Washington that's kept open all year round! Nestled in the northeastern part of the state, a world away from the hustle and bustle, most of this gorgeous drive winds through the Colville National Forest. You're basically surrounded by epic scenery with hardly any other cars around. Plus, you're cruising along a historic route once used by Native Americans heading to the Columbia River for fishing! Later, wagons came rumbling through, and the whole thing was named after Civil War General William T. Sherman, who rolled through back in 1883. The road? Paved, baby! State Route 20, also known as the Sherman Pass Scenic Byway, is smooth sailing all the way to the top. Sure, it's steep in sections, but the views are SO worth it. Seriously, they don't call it "The Most Beautiful Mountain Highway" in Washington for nothing! The whole shebang is just under 37 miles long, stretching from near Republic on WA-21 all the way east to Kettle Falls on US-395. My advice? Hit this road between late spring and early fall for the ultimate escape. Trust me, it's the perfect way to ditch civilization and reconnect with nature (and some seriously stunning vistas).
