Sunny Jim Cave (accessed through The Cave Store)

Sunny Jim Cave in La Jolla is a sea cave that is reached by descending a narrow, hand-dug tunnel and stairway inside The Cave Store; there is no direct public entrance from the shoreline. The tunnel entrance through the storefront makes the cave's land access unusually concealed compared with most sea caves. The feature is a documented tourist attraction but is physically hidden and only reachable via the business's interior passage.
