Humboldt County, California

Humboldt County is way up north on the coast. It’s redwood country, with trees taller than skyscrapers. They like to say, “Come for the trees, stay for the tranquility.”
Eureka is the biggest city, with a cool old town full of Victorian buildings. The place has a reputation for… um, certain plants. California State Polytechnic University, Humboldt keeps things lively.
Highway 101 is the main artery. It winds through ancient forests and along stunning coastlines. If you like your towns quirky and your nature wild, Humboldt’s your spot.
