Seattle to Pocatello Road Trip: Epic 11-Hour Drive Guide

The drive from Seattle, WA to Pocatello, ID spans approximately 685 miles across Washington, Oregon, and Idaho. Most travelers take I-84 via Pendleton or the scenic US-395 through Spokane. A little-known fact: part of US-395 follows the old Oregon Trail near the Blue Mountains, where wagon ruts are still visible at designated pullouts.

This route crosses the Columbia River Plateau, the Blue Mountains, and the Snake River Plain. You'll witness dramatic elevation changes from sea level to over 4,000 feet. The drive typically takes 10-12 hours without stops, but we recommend two days to fully explore.
