Is Mermaid’s Grotto worth visiting?
Absolutely – but be prepared for a bit of a rugged access, variable conditions if you swim, dive, or snorkel — but some of the most incredible finds along the shore as well. If you’re on island, and looking for a tucked away beach that never disappoints — this is one of my favorites.
Forget the glossy guide-book beaches — Mermaid’s Grotto is where you trade flip-flops for sneakers and exploration.
Mermaid’s Grotto in Onna, Okinawa is one of the island’s most beautiful spots.
If you came looking for dive briefings or tank rentals, you might be in the wrong place — but if you’re here to explore Okinawa’s beauty up close, you’ll be ready for adventure in no time.
What is Mermaid’s Grotto like?
Some places just feel like magic the moment you reach them.
Mermaid’s Grotto is one of those – completely natural, a little hidden (thanks jungle path), and a whole lot of wow.
It’s not flashy or overcrowded, and I’ve never seen a beach umbrella.
It’s just untouched beauty.
Just you, the waves skipping over coral with that faint jingle, and a chance to really experience Okinawa – one tide pool and bolder at a time.
A Beach Made for Wandering
While some know Mermaid’s Grotto for the diving, I know it for wandering. It’s a long stretch that curves along ancient family tombs and ends in a cliff wall – with another seaside cave waiting on the opposite side.
We’ve found abalone. Bits of old Japanese pottery. A sea-glass marble.
Itching to explore. I’d bet you’re an Island Adventurer.

Go at low tide for endless discovery. The tide pools are bursting with blue darlings, schools of darting fish, and shy creatures that only show up after you’ve waited them out.
Wander into the grotto – with it’s coral-rock paths and tide pools on every side – it’s like stepping into another world.
The thing about Mermaid’s Grotto is, it shifts and changes – with the tide and the weather. I’ve been countless times, and it’s always a little different.
Sometimes, it’s treasure hunting after the big typhoon.
Sometimes, it’s a place to sit still and let the beauty wash over you.
It’s one of my favorite places to slowly explore, especially when I need a reminder to slow down and just be here. To take it all in.
Oh! And let’s not forget the sunsets here!
Mermaid’s Grotto is one of my know-it’s-going-to-be-great sunset spots that never lets me down.
A few of my favorites are pieces like Sunkissed, Sublime and Triumph.
They’re all different evenings, completely different moods, but the same sun-spilling magic in the same place.
Before You Go: Essential Tips
📍 Google Map Pin
You’ll follow a small road that curves through some farmland.
There are a few jungle path entrances that lead to the beach—they’ll all take you to the same place.
👟 Wear tennis shoes
There’s a lot of sharp coral, and the jungle path in is uneven.
☀️ Wear a UV shirt or bring sun protection
There’s almost no shade, and lobster isn’t in style anymore.
🌿 Bring a flashlight if you’ll be there to watch the sunset
The walk back through the jungle tunnel gets dark quickly after sunset.
🙏 Be respectful near family graves
A few family graves are tucked along the cliff facing the beach. Please avoid touching or climbing.
🚗 Park carefully
Roadside only. Tuck in neatly and be mindful of the nearby farms.
⚠️ Safety Notes
Mermaid’s Grotto is famed to have some of the best snorkeling + diving in Okinawa — and while this may be true, conditions can shift fast, and many have been caught off guard.
Prominent signs at the entrances warn of the danger.
If you’re not experienced, it’s best to skip the snorkeling and diving, and choose safer locations like Diamond Beach or Blue Cave for off-shore adventures instead.
If you do ever see someone in distress from shore, call the number on the back of your SOFA license to get to the Military Police. They can dispatch help quickly — and without the language barrier.
Take a Moment to Fall in Love
Let the sun set slowly over your toes. Listen to the waves. Pick up a shell.
Soak it all in while you’re here.
Because this little corner of Okinawa–I guarantee it’s going to live in your heart long after you leave
