There is just one National Park, but it is surrounded by a number of State Parks. The feds and the state actually (or used to) jointly administer the area around Prairie Creek (Elk Prairie). Take the road out to fern Canyon.
When I used to live up there, one of my favorites was Patricks Point State Park at Trinidad. Big trees, moonstone beach, terrific views (on clear days.) Actually the entire State Park system running from Richardson's Grove (south of Garberville) up to Jedediah at the Oregon border is IMHO one of the better offerings in the State system. You can't really go wrong until you drop down into the County run parks.
There are a number of off the beaten path parks and campgrounds as well as Six Rivers National Forest to visit. Make sure to get off Hwy 101 and take the Avenue of the Giants. Lots of groves to stop at and view the big trees. Along the river, look for the 1964 high water mark, it will blow you away. Unfortunately there is not a lot to see in Scotia anymore. Check out the Clark Museum in Eureka.
Hope that helps.
