Humboldt Redwoods Interpretive Association

The Humboldt Redwoods Interpretive Association (HRIA) is a 501(c) non-profit, providing volunteer-run Visitor Centers at four State Parks in Humboldt County. We hope that you will stop by to get information about hikes, directions, ecology, history, as well as maps, brochures, books, and souvenirs. We strive to connect visitors and the community to the incredible redwood forest, in hopes of spreading appreciation and a passion for the conservation of the tallest trees in the world.
