Where is Siskiyou Summit?

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.
