Depoe Bay  is situated along a truly beautiful coastline that cannot be fully appreciated from the highway. A quarter-mile-long seawall and promenade invite a stroll. For a panorama of the harbor, continue along the sidewalks across the gracefully arching concrete bridge, designed by Conde McCullough and built in 1927.
Other nice perspectives are offered from residential streets west of U.S. 101; try Ellingson Street, south of the bridge, and Sunset Street, at the north end of the bay. Two “spouting horns,” natural blowholes in the rocks north of the harbor entrance, can send plumes of spray 60 feet into the air when the tide and waves are right.
East of the bridge is Depoe Bay’s claim to international fame, the world’s smallest navigable natural harbor. This boat basin is also exceptional because it’s a harbor within a harbor. This topography is the result of wave action cutting into the basalt over eons until a 50-foot passageway leading to a six-acre inland lagoon was created.
In addition to whale-watching, folks congregate on the bridge between the ocean and the harbor to watch boats maneuver into the enclosure. Depoe Bay’s Harbor was scenic enough to be selected as the site from which Jack Nicholson commandeered a yacht for his mental patient crew in One Flew Over the Cuckoo’s Nest.
