Coeur d'Alene to Ferndale: Epic PCH Road Trip Guide

This route from Coeur d'Alene, ID to Ferndale, CA spans roughly 700 miles (1,120 km) and takes about 12-14 hours of pure driving time, but you'll want to stretch it over several days. The journey traverses the Idaho Panhandle, crosses the Columbia River Plateau, dips through the Oregon Coast Range, and finally meets the Pacific at the Humboldt County line.

A little-known fact: the section of US-101 between the Oregon border and Ferndale is part of the original Redwood Highway, built in the 1920s to connect the lumber towns. Today it winds through ancient redwood groves that have stood since before the highway existed.

Infrastructure Safety & Road Quality: Most of the route is excellent, but be aware that US-101 from the Oregon border to Eureka has narrow shoulders, sharp curves, and occasional rock slides. In winter, black ice is common on I-90 east of Spokane and on passes. Always carry chains if traveling November to March.
