Consider a trip out to the North Jetty for wave watching and on to the Samoa Cookhouse for lumberjack style meals served family style. Timber was king in this region for many years and for many the Cookhouse brings back the feel of those times. Eureka Chamber of Commerce: http://www.eurekachamber.com
