At Copalis State Airport, the runway is the beach itself -- 4,500 feet of packed sand stretching from the mouth of the Copalis River to a line of rocks a mile north. When the tide comes in, the runway disappears. When it goes out, pilots land on what the Pacific Ocean has temporarily agreed to lend them. This is the only airport in Washington State where landing on the beach is legal, and the only FAA-approved beach runway in America. Its FAA identifier is S16. Its elevation is one foot above mean sea level. Everything about this place operates at the margin between land and water, between the permanent and the provisional.

Copalis State Airport: Landing on Borrowed Ground

Wed, 18 Mar 2026 00:00:00 GMT

Photo credit Jelson25, Public domain. There is something clarifying about an airport that the ocean can erase. Pilots who fly into S16 must plan around tide charts, not just wind and weather. A late departure means no runway to return to. A miscalculated approach puts wheels into surf rather than sand. The experience...
