Siskiyou Summit in Oregon is one of the more perilous sections of Interstate 5

Okay, road trip fans, listen up! Let's talk about Siskiyou Summit, a seriously epic mountain pass hanging out in Jackson County, Oregon. We're talking 4,310 feet above sea level, so get ready for some views!

Just a hop, skip, and a jump (well, about 4 miles) from the California border, you'll find this beauty nestled in the Siskiyou Mountains. You'll be cruising on Interstate 5 (aka the Pacific Highway), and this pass is the king of the hill when it comes to elevation on that route.

This north-south stretch of road is right in the heart of the Cascade-Siskiyou National Monument. You'll be rolling from Medford, Oregon, down to Yreka, California – a 51.1-mile journey.

Now, heads up – things get a little spicy here. Depending on which way you're going, you'll either be gaining or losing a whopping 2,300 feet in just 6 miles thanks to some pretty steep 6% grades. That northbound section from Milepost 18? Yeah, that's a 6% downhill grade, dropping 2,000 feet in under 10 km. The descent can be especially tricky, particularly when fog rolls in and visibility drops to near zero. And get this – despite the challenges, around 13,000 trucks use this route *every single day*.

Keep in mind: you're in the mountains! Altitude and crazy weather are always in play. Its location near the Pacific combined with its elevation and winding curves can bring heavy snowfall and freezing rain, sometimes forcing road closures during the winter. Snow is common from November to April, and the road can be shut down for days during severe weather, and sometimes even when the weather seems fine. During winter, expect snow and ice on the road. Definitely avoid driving at night or early morning during these months, and keep an ear on the radio for weather and road condition updates. It’s a road trip to remember (if you plan ahead)!
