Year-round
Siskiyou Summit, nestled in Oregon's Jackson County, is a real stunner! This mountain pass, soaring to 4,310 feet, straddles the Siskiyou Mountains just 4 miles north of the California border.
You'll be cruising on Interstate 5 (Pacific Highway), entirely paved, making it super accessible. Fun fact: it's the highest point on this major route!
Clocking in at about 51 miles, this stretch of road runs from Medford, Oregon, to Yreka, California, right through the beautiful Cascade-Siskiyou National Monument.
But, heads up, it's not all smooth sailing! Depending on your direction, you'll either be gaining or losing a hefty 2,300 feet in just 6 miles, with some pretty steep 6% grades thrown in for good measure. There's a particularly intense part heading north from Milepost 18, where you're climbing 2,000 feet in a short 6-mile burst.
The descent can be tricky, especially when fog rolls in and visibility drops to near zero. Despite the challenges, you'll see a ton of trucks navigating this route daily!
Word to the wise: this is mountain country, so weather is always a factor. With its elevation and proximity to the Pacific, Siskiyou Summit sees a lot of snow and freezing rain, especially from November to April. Oregon D.O.T. might even shut down the whole highway during winter storms. Closures can happen even when the weather seems fine, so always be prepared.
Driving at night or early morning in winter? Maybe skip it. Definitely tune into weather updates and road conditions before and during your drive to stay safe.

extremePajarito Mountain
🇺🇸 Usa
Okay, adventure seekers, listen up! If you're in north-central New Mexico, specifically Los Alamos County, and craving a serious off-road experience, then Pajarito Mountain is calling your name! This peak punches up to a whopping 10,360 feet, making it one of the highest drives in the state. Nestled on the eastern flank of the Jemez Mountains, the road to the top is a beast – think gravel, seriously rocky, and downright treacherous in spots. You absolutely need a 4x4 to even consider this one. Keep a close eye on the weather, because things can change on a dime up there, and closures are common. Seriously, only attempt this when it's dry! A word to the wise: if you have any respiratory or heart issues, this isn't the drive for you. The altitude and extreme weather are no joke, no matter the time of year. And be prepared for wind – it’s a constant companion at these heights. But hey, if you're up for the challenge, the views are probably insane!
hardAn awe-inspiring drive to Paulina Peak in Oregon
🇺🇸 Usa
Wanna experience one of Oregon's highest roads? Head to Paulina Peak in Deschutes County, nestled within the Newberry National Volcanic Monument. The road, NF-500 (Paulina Peak Road), kicks off from Forest Service Road 21 and stretches for about 3.9 miles to the top. It's unpaved, so expect a bit of a bumpy ride, but most cars can make it. Just be aware that it can get pretty narrow and rough in spots. Shorter vehicles (under 23 feet) are recommended. Don't forget your recreation pass for parking! Get ready for a climb! You'll gain about 1,578 feet in elevation, with some sections hitting a 9% grade. The road is typically open from early July to late October/early November, depending on the snow. Trust me, the views are worth it. This spot offers incredible panoramic views of the Newberry Caldera, the volcano's flanks, the Cascades, and beyond. On a clear day, you can even spot Mt. Shasta in California and Mt. Adams in Washington. Oh, and keep an eye out for bears – they're known to hang around the campsites in the crater! Allocate at least 25 minutes for the drive, but you'll want to budget extra time for photos and exploring.
