Five miles of saltwater on the north end of Whidbey Island, opening east into Saratoga Passage. The mussel rafts sit in the middle of the cove; the Coupeville wharf, red and barn-shaped, juts off the south shore where the town has stood since 1853. The wind drops most afternoons. Eagles work the eelgrass for herring. Out by Penn Cove Shellfish the boats come in slow, hauling the lines the mussels grew on. Up the road, the Ebey's Prairie holds the long view of the cove from the bluff.
