Arcata Airport

Arcata airport is plagued year-round by coastal stratus, even sometimes going below ILS minimums for relatively long stretches. But the airport cafe -- Silver Lining, in the main terminal building -- is pretty good for an airport cafe (their fish and chips worked for me, and I'm British), and the Arcata / Eureka area is a lovely place to stay (there's a good selection of Bed and Breakfast places in Arcata).

Note that smaller GA planes might find Eureka (Murray Field) just down the coast cheaper and more convenient if the weather's VFR or above Eureka's approach minimums, but Arcata's a good all-round choice in any case.
