Warm Beach (Lushootseed: dxʷtux̌ʷub)[4][5] is a census-designated place (CDP) in Snohomish County, Washington, United States.

[4][5] Seattle real estate developer Clarence Dayton Hillman acquired 12,000 acres (4,900 ha) along Port Susan in 1906 and began to sell property for a future seaport city named "Birmingham" for his Michigan hometown.

By 1910, he had sold plots and ran an excursion steamer to the site, where paid actors were used to create the illusion of a thriving city.

The scheme was later uncovered and Hillman was sentenced to 2.5 years in prison for mail fraud.

[10] A Christian summer camp was established at Warm Beach in 1956 by the Free Methodist Church and opened two years later.

It hosts an annual Christmas lights festival in December that was inspired by the Opryland Themepark in Tennessee.
