The Secret Sea Caves of La Jolla: Descending into Sunny Jim Cave

San Diego is world-renowned for its pristine, sun-drenched beaches and laid-back surf culture. However, hidden just beneath the bustling streets of La Jolla lies a dark, damp, and historically rich subterranean secret. While kayakers frequently explore the seven sea caves carved into the sandstone cliffs of La Jolla Cove from the water, only one of these magnificent geological formations can be accessed directly from land: the famous Sunny Jim Cave. Descending into its depths is a journey through early 20th-century history, complete with tales of relentless manual labor and Prohibition-era bootlegging.

Two Years of Hand-Dug History

The story of land access to Sunny Jim Cave begins in 1902 with an ambitious and somewhat eccentric German immigrant named Gustav Schultz. An artist and former mining engineer, Schultz owned the property directly above the caves. Seeing an opportunity for a unique tourist attraction, he decided to create a tunnel from his shop straight down into the largest of the caverns. To accomplish this monumental task, he hired two Chinese laborers.

Working entirely by hand with nothing more than picks, shovels, and sheer determination, these laborers spent nearly two solid years chipping away at the dense sandstone. When the tunnel was finally completed around 1904, it was an engineering marvel. In the earliest days of operation, tourists eager to see the cave were actually lowered down the steep shaft using a rope! Thankfully, a wooden staircase consisting of 145 steps was eventually constructed, making the descent significantly safer and more accessible to the general public.

How Sunny Jim Got His Name

The cave's unusual name has a surprisingly literary origin. During a visit to La Jolla in the early 1900s, L. Frank Baum, the legendary author of *The Wonderful Wizard of Oz*, took a tour of the newly accessible cave. Looking out from the dark interior toward the bright opening where the ocean crashes in, Baum remarked that the silhouette of the cave mouth looked exactly like the profile of "Sunny Jim." At the time, Sunny Jim was a highly recognizable, cartoonish mascot for a popular British wheat cereal called *Force*. The moniker stuck instantly, and it has been known as Sunny Jim Cave ever since.

Beyond its quirky name, the tunnel carries a darker, more illicit history. Local legends and historical accounts suggest that during the Prohibition era of the 1920s, the secluded, subterranean passageway was utilized by bootleggers. Smugglers would allegedly use the cover of darkness to bring illegal whiskey, and sometimes even opium, into San Diego via the cave, hauling the contraband up the stairs and straight into the city.
