Sunny Jim Sea Cave and The Cave Store (La Jolla)

The Sunny Jim sea cave in La Jolla is a natural sea cave accessed by a hand-cut tunnel and stairway beneath a storefront now known as The Cave Store. The trademarked name "Sunny Jim" dates to early 20th-century local usage tied to a cartoon cereal mascot, and the tunnel was created to provide tourist access to the cave, which historically housed vendors and attractions. The site remains an unusual coastal feature and tourist stop where the man-made access and its advertising-driven name are part of the location's odd local history.
