San Francisco to Portland is a big drive up the West Coast — about 640 miles via I-5 through Sacramento, Redding, and the Cascades. It's an excellent Pacific Northwest road trip when done over two days.
The I-5 corridor passes through some striking terrain: the California Central Valley, then the dramatic Shasta and Klamath mountain landscapes, before descending through the lush Willamette Valley into Portland.
Stops Along the Way
The natural first-day stopping point, set beneath Mount Shasta and the Cascades — a logical overnight midway.
Oregon's arts destination, home of the Oregon Shakespeare Festival and a beautiful downtown, about 2.5 hours south of Portland.
University of Oregon's vibrant college town with great food and outdoor culture, just over an hour from Portland.
Tips for This Trip
Split across two days with an overnight in Redding or Ashland
A 10-hour drive is doable in one day but exhausting — Redding for a budget stop, or Ashland for something memorable.
Mount Shasta is worth a detour
The drive past Mount Shasta on I-5 is one of the most dramatic in America — consider stopping at Stewart Mineral Springs or Castle Crags State Park.
December–March brings snow to Siskiyou Pass
The Siskiyou Summit on I-5 (elevation 4,310 ft) can close in winter storms — check road conditions before departing in those months.
