This 100-Year-Old Tunnel Is California’s Best-Kept Coastal Secret
It starts off like a typical visit to a quirky seaside shop — charming, colorful, full of coastal knickknacks. But then you notice the stairs. And suddenly, you’re walking down a narrow, dimly lit tunnel carved straight through sandstone, and it hits you: this isn’t your average beach town stop.
What you’re entering is Sunny Jim’s Sea Cave — one of La Jolla’s most iconic hidden gems and the only sea cave in California that you can actually walk into from land.
The Vibe: Mysterious Meets Magical
🌀 The tunnel was hand-dug back in 1902 by a laborer hired by German artist Gustav Schultz (we love a dramatic backstory).
🌊 After descending 145 steps, you’ll find yourself inside a coastal cavern with a window to the Pacific — waves echoing, light spilling in, and a salty breeze that makes it all feel like a fairytale.
👀 It’s also named “Sunny Jim” because the cave’s mouth supposedly resembles a cartoon cereal mascot. Yes, really.
Here’s What You Need to Know
- You’ll enter through the Cave Store, a cliffside shop perched above La Jolla Cove.
- It costs a few dollars to access the tunnel — totally worth it for the view and experience.
- It can be a bit slippery and steep, so wear solid shoes and take your time on the stairs.
Pro Tip 📸
Go at sunset for that golden glow pouring through the cave’s opening — it’s straight-up cinematic. And don’t forget to explore the surrounding coastal trails and tide pools afterward.
For a truly offbeat, under-the-radar adventure, Sunny Jim’s Sea Cave is an unforgettable detour in the heart of La Jolla.
