Del Norte County.
North of Klamath, visit the End of the trail Museum at the Trees of Mystery attraction; it has a large collection of Native American artifacts. You'll be greeted by statues of legendary lumberjack Paul Bunyan and his blue ox, Babe.
In Crescent City, watch local fishing boats unload their catch-or try fishing in the Klamath and Smith Rivers. This is the northern gateway to the Redwood National Park. Offshore, see the oldest Pacific Coast working lighthouse in Crescent City.
