Haystack Rock is a 235-foot (72-meter) sea stack in Cannon Beach, Oregon. It is sometimes claimed locally to be the third-tallest such "intertidal" (meaning it can be reached by land) structure in the world, but there are no official references to support this. A popular tourist destination, the monolithic rock is adjacent to the beach and accessible by foot at low tide. The Haystack Rock tide pools are home to many intertidal animals, including starfish, sea anemone, crabs, chitons, limpets, and sea slugs.
