Seaside is a small resort city in northwestern Oregon, known for surf breaks and 1920s promenade. The Seaside Aquarium is one of the oldest in the United States, and includes touch tanks and a seal exhibit. To the south, Tillamook Head National Recreation Trail climbs a forested cape to Ecola State Park, with views of the 19th-century Tillamook Rock Lighthouse. One of the Oregon Coast’s busiest destinations, Seaside hosts thousands of visitors each year.
