Travel website Bonus Finder crunched data from social media to find the most-photographed pools in America

The Mandalay Bay in Las Vegas took the #1 slot. But a California pool came in 3rd place.

The Neptune Pool at Hearst Castle in San Simeon, California is the #3 most photographed in America

Construction on the stunning pool began in 1924. It is 104 feet long, 95 feet wide, and holds 345,000 gallons of water.

The Neptune Pool has dramatic architectural features and carvings can't actually swim in it! The pool is a historical structure and isn't open for swimmers.

Still, you can take a great selfie beside the pool, as tens of thousands do each year.
