Walk into a jewelry and souvenir shop on Prospect Street and you’ll see some shiny shells and overpriced t-shirts. It looks normal. But then you notice a wooden door in the corner that looks like it belongs in a Victorian basement. Pay five bucks, and you’re headed down a tunnel hand-dug by two Chinese laborers in 1902. Honestly, the La Jolla Cave Store is one of those places that should feel like a tourist trap, yet it remains one of the most authentic slices of San Diego history you can actually touch.
The tunnel is damp. It’s narrow. It smells like salt and old earth.
Most people come to La Jolla for the sea lions or the high-end sushi, but this literal hole in the ground is the only way to access Sunny Jim Sea Cave by land. There are seven main caves along this stretch of sandstone cliffs, but Sunny Jim is the crown jewel because of that man-made shortcut. Without it, you’d be kayaking through unpredictable swells just to see the interior.
The Weird History of Sunny Jim Cave
The story starts with Gustav Schultz. He was a German engineer and a bit of a dreamer who arrived in La Jolla around 1902. He didn't just want a view; he wanted an attraction. He hired two men to dig through the soft sandstone with picks and shovels. It took them two years. That’s a lot of manual labor for a view of the ocean, but Schultz was thinking ahead.
Legend has it—and historians like to debate this—that the tunnel was used for more than just sightseeing during Prohibition. Some say bootleggers smuggled crates of whiskey up those 145 steps to avoid the authorities. While hard evidence of a massive smuggling ring is thin, the geography makes it a perfect "what if" scenario.
Why the name Sunny Jim? It wasn't named after a local surfer or a fisherman. It was actually Frank Baum, the author of The Wonderful Wizard of Oz, who coined the name. He thought the silhouette of the cave opening looked exactly like a popular British cereal mascot from the early 1900s named Sunny Jim. If you stand at the bottom of the stairs and look out toward the ocean, the profile of the rocks creates a jagged face. You can see the forehead, the nose, and the chin clear as day.

What the Descent is Really Like
Don't wear flip-flops. Seriously.
The 145 wooden steps are often slippery because of the constant sea spray and humidity. It’s a steep drop. If you have bad knees or a fear of tight spaces, this might be a "skip it" moment for you. But for everyone else, the transition from a brightly lit gift shop to a dark, cool subterranean passage is a trip.
The temperature drops about ten degrees by the time you reach the bottom.
Once you’re on the viewing platform at the base, the sound hits you first. The roar of the Pacific echoing off the cave walls is deafening during high tide. You’ll see kayakers bobbing around in the mouth of the cave, looking in at you while you look out at them. It’s a strange, shared moment between the people who paddled a mile and the people who just walked down some stairs in a shop.
Common Misconceptions About the La Jolla Cave Store
A lot of people think the Cave Store is just a lobby for a state park. It isn't. It's a privately owned business. This surprises folks who expect a National Park Service ranger to be standing there with a hat and a clipboard. Instead, you get local staff who know the tides and can tell you if the cave is currently "splashing," which is code for "you’re going to get wet if you stand too close to the edge."

Another myth? That you can swim through the cave to the store.
Please don't try this. The currents around the Seven Sea Caves are notorious. Lifeguards at La Jolla Cove spend a significant amount of their time rescuing people who underestimate the "surge." The cave is for viewing, not for a triathlon practice session.
The cave itself is carved out of 75-million-year-old Cretaceous sandstone. It’s fragile. You’ll see names carved into the walls from decades ago—don’t be that person. The mineral stains on the walls create these weird, psychedelic patterns of reds, purples, and yellows. That’s iron oxide and manganese seeping through the rock. It looks like street art, but it’s just geology doing its thing.
Planning Your Visit Without the Stress
Timing is everything in La Jolla. If you show up at 1:00 PM on a Saturday in July, you’re going to be waiting in a line that stretches past the shell necklaces and out the front door.
- Go Early: The store usually opens around 9:00 or 10:00 AM. Being the first one down the stairs means you get the echo all to yourself.
- Check the Tides: A "king tide" or a massive swell can sometimes close the lower platform for safety. If the weather looks gnarly, call ahead.
- Parking is a Nightmare: Prospect Street and Coast Blvd are notoriously difficult for parking. Look for spots a few blocks uphill on Eads Ave or Draper Ave and enjoy the walk down.
- The "Secret" View: If you don't want to pay the entrance fee, you can still see the cliffs. Walk behind the store to the start of the Coast Walk Trail. It’s a dirt path that hugs the cliffs and gives you a view of the other six caves from above.
The Business of the Cave
The Cave Store has changed hands over the decades, but it has maintained that quirky, old-California vibe. It’s one of the few places left in La Jolla that hasn't been completely sanitized by corporate luxury. Yes, they sell souvenirs. Yes, it’s a business. But they also preserve a piece of engineering that would likely never be permitted to be built today due to environmental regulations and coastal commissions.
It represents a time when you could just decide to dig a hole to the ocean because you thought it would be cool.

Actionable Insights for Your Trip
If you're actually going to do this, bring a light jacket. Even in the middle of a San Diego heatwave, the tunnel holds onto the damp chill. Also, keep your phone or camera on a wrist strap. If you drop your iPhone into the surging water at the bottom of Sunny Jim, it belongs to the Pacific Ocean now. There is no retrieving it.
After you finish the cave, head north on the Coast Walk Trail for about ten minutes. Most tourists stop at the store and turn around. If you keep going, you’ll hit the "Clam's Cave," which is the only other cave visible from the cliffs without a boat. It’s a great spot for photos that don't have twenty other people in the background.
To get the most out of the experience, spend five minutes at the bottom just being quiet. Most people take a selfie and run back up because they're winded. If you wait, you’ll see the way the light changes on the water and maybe spot a sea lion poking its head up near the entrance. That’s the real magic of the La Jolla Cave Store—it’s a window into a world that usually requires a boat and a life jacket to see.
Next Steps for Your Visit:
- Verify Hours: Check their official site or call (858) 459-0746 before heading out, as private events or weather can shift closing times.
- Footwear Choice: Wear sneakers with actual grip; the moisture makes the wooden stairs feel like an ice rink.
- Combine Activities: Pair the cave visit with a walk to the Children’s Pool (about 15 minutes away) to see the harbor seals, making it a full "wildlife and history" morning.
- Support Local: Buy a small memento from the shop; the revenue from the store is what funds the constant maintenance required to keep a century-old salt-exposed tunnel safe for the public.
