<P> The Depoe Bay Ocean Wayside was built after residents of Depoe Bay implored the Oregon State Highway Department for a restroom facility at the popular location . Conceptual designs were developed by landscape architect Harold Spooner, with four designs: an entirely unobtrusive structure below road level, a low flat - roofed building, a flat - roofed building with a prominent lighthouse - like tower, and a flat - roofed structure (labeled "Cliff House") with an octagonal cupola . The last alternate was chosen, with alterations to incorporate interior stairways and an overall lowering of grade to avoid blocking the view from the highway . Spooner's concept was developed by Oregon Highway Department Carl Schneider . The wayside was completed in June 1956 . The main level has been occupied by a series of concessionaires, a condition imposed by the state, concerned that the property be self - supporting . It has been described as a smaller version of Vista House at Crown Point on the Columbia River, and serves a similar purpose . </P> <P> The Depoe Bay wayside was operated by the Oregon Department of Transportation until 1988, when it was transferred to Depoe Bay . In 2008 it was again transferred to the Oregon Parks and Recreation Department . It has been used as a lookout for watching gray whales since 2005 . </P> <P> Approximately 20,000 whales migrate southward past the center from mid-December to end of January each year . The same number migrate northward, but are distributed throughout mid-March through the first week of June . Gray whales are the most commonly sighted whales year round along the Oregon Coast . Prime viewing is during the migration seasons of December through January, and March through June . July will bring summer feeding whales with peak viewing August through October . Summer is when the whales are the closest to shore making them easier to watch . Other types of whales observed are humpbacks, minkes, orca, and sometimes sperm and blue whale . There are approximately 2500 unique whale individuals observed from the center each year . </P> <P> The center is free to enter, has binoculars for public use, and is out of the weather . </P>
