WA Peninsula map Long BeachOriginally platted as Tinkerville in 1881, the town of Long Beach flourished with the building of the Ilwaco Railroad & Navigation Company’s narrow-gauge railroad that ran from the docks of Ilwaco to its northern terminus at Nahcotta. Long Beach quickly established itself as a tourist destination and hotels, shops and even an indoor swimming pool sprouted up to serve the beach-goers. Today Long Beach is the peninsula’s largest town and hosts a full schedule of colorful summer events.
