Exploring the Magical Blue Cave Vanuatu – Our Third Morning on Tanna
After two nights of fiery adventure near the Tanna Vanuatu Volcano, our third morning on the island felt calmer — though still filled with excitement. Taniya and I woke up early, our faces still marked by a thin layer of volcanic ash from the night before. The soft sound of waves replaced the roaring echoes of Mount Yasur, and I remember saying, “Maybe today we’ll find the quiet side of Tanna.”
Our host, Samuel, smiled knowingly and said, “You will see something different — the Blue Cave.” He pointed toward the western coast of the island, where limestone cliffs met the endless blue of the Pacific Ocean. I had seen a few pictures of the Blue Cave Vanuatu, but none of them seemed real. The idea of swimming through an underwater tunnel into a hidden chamber glowing with sapphire light sounded almost mythical.
We packed lightly — just swimwear, our waterproof camera, and a towel each. The 4×4 ride to the west coast was much smoother than the one to Mount Yasur. Coconut palms swayed over the dusty road, and children waved as we passed by. The air smelled of salt and seaweed instead of sulfur, and that contrast made me smile.
When we finally reached the coastline near the village of Louinio, the water was unbelievably clear. Small boats rocked gently against the waves, and the guides were already preparing snorkeling gear. Taniya looked at me and whispered, “I hope I don’t mess up the dive.” I laughed, remembering how she tripped on the volcanic trail the previous day. The moment we climbed into the boat, I could already see faint shades of turquoise shimmering beneath the surface — a promise of the beauty waiting inside the Blue Cave Tanna Vanuatu.
This story continues from our journey to the legendary Tanna Vanuatu Volcano, where fire met the stars before we discovered the peaceful magic of the Blue Cave.
1️⃣ 🗺️ Destination Overview
The Blue Cave Vanuatu is one of the most spectacular natural wonders on Tanna Island, located off the island’s northwest coast. It’s a large sea cave hidden within tall limestone cliffs, only accessible by swimming through a short underwater passage.
At high tide, visitors must dive under a narrow opening for about two to three seconds before emerging inside. At low tide, the entrance is partly visible, and you can simply duck your head below the surface. Inside, the sunlight streams through the entrance and bounces off the water, filling the chamber with an almost electric blue glow.
This isn’t just a place for swimming — it’s an otherworldly experience. The Blue Cave Tanna is sacred to some locals, who call it a “place of calm” or “the heart of the sea.” Many believe it holds spiritual energy that contrasts the fiery power of Mount Yasur.
Most tours to the Blue Cave Tanna Vanuatu start from Lenakel or nearby villages on the western coast. The trip usually includes a short boat ride, snorkeling gear, and a local guide. Though less famous than the volcano, the Blue Cave offers a completely different side of Tanna — serene, mystical, and deeply connected to nature’s beauty.
2️⃣ 💭 Why I Chose to Visit Blue Cave Vanuatu
After the intense energy of Mount Yasur Vanuatu, I wanted something that would balance that experience — a moment of peace after the chaos of fire. The locals often spoke of the Blue Cave Vanuatu as a sacred spot where water and light create harmony. That description alone made me curious.
I’ve always been fascinated by natural contrasts — fire and water, noise and silence, fear and calm. So on our third morning, when Samuel suggested visiting the cave, I instantly agreed. Taniya loved the idea too; she said it would be her “underwater temple moment.”
Another reason I wanted to go was the sense of mystery. Many travelers write about the volcano, but far fewer describe the cave in detail. I wanted to see it for myself and tell the story of this quieter, lesser-known side of Tanna. I didn’t know it yet, but that morning swim through the Blue Cave would become one of the most peaceful and unforgettable memories of our entire journey.
3️⃣ 🎢 My Favorite Things to Do
1. The Boat Ride to the Cave
Our boat ride to the Blue Cave Tanna Vanuatu lasted only 15 minutes, but it felt like entering a dream. The ocean was calm, and the cliffs loomed higher with every minute. The guide, a cheerful man named Kal, told us, “You will swim through the ocean’s door.”
As we approached, the limestone walls looked solid — no sign of a cave. Then suddenly, Kal pointed to a tiny hole near the waterline. “That’s the entrance,” he said with a grin. Taniya’s eyes widened. “You mean we actually swim through that?”
He laughed. “Yes, just two seconds under the water. Don’t worry, I’ll go first.
2. Diving into the Blue
When it was my turn, I took a deep breath and went under. For a brief moment, everything went silent — no sound, no light, just cool blue water around me. Then I emerged inside the cave, and what I saw made me forget to breathe.
The chamber glowed with vivid, otherworldly blue light. The sunlight filtered through the entrance and reflected off the sandy floor, creating moving patterns on the limestone walls. Every ripple of water seemed to sparkle. “Oh my God, it’s like swimming inside a gemstone!”
3. Floating in Silence
Once everyone was inside, the guide told us to stay quiet for a minute. No splashing, no talking — just float. The sound of our breathing mixed with soft water ripples and distant waves outside. It felt like time had stopped.
I closed my eyes and thought about how the day before, I was standing on the rim of Tanna Vanuatu Volcano, surrounded by fire and ash — and now, less than 24 hours later, I was floating in the cool heart of the ocean. The contrast was poetic.
4. Photography and Funny Mistakes
Of course, I couldn’t resist taking photos. The light was tricky; every picture came out brighter or darker than expected. Taniya tried to take a selfie and accidentally dunked the camera underwater while laughing. Luckily, it was waterproof — though she almost lost her snorkeling mask in the process.
The reflections inside the Blue Cave Vanuatu are unreal for photography. Every few seconds, the shade of blue changes — from sapphire to turquoise to silver. No filter could do it justice.
5. Meeting the Locals by the Shore
After leaving the cave, we stopped by a small beach nearby. The villagers greeted us with smiles and coconuts. One elder woman, wearing a flower crown, told us how the cave is considered a gift from the sea spirits.
Listening to her made me appreciate how the people of Tanna live in harmony with nature — the volcano for fire, and the cave for water. Both are parts of their story, and now, ours too. As the boat headed back, the sunlight danced on the waves. I remember thinking: maybe this was Tanna’s way of saying goodbye — calm, peaceful, and endlessly beautiful.
4️⃣ 🚗 How I Got There
Getting to the Blue Cave Vanuatu was much easier than our wild ride to Mount Yasur. From our stay near Lenakel, we arranged a half-day tour through a local guide named Kal, who also handled our volcano trip earlier. The drive to the western coast took around 40 minutes by 4×4.
The road was mostly unpaved but smoother than expected, passing through coconut plantations and small coastal villages. Along the way, kids waved at us, shouting “Blue Cave! Blue Cave!” — clearly familiar with the tourist ritual.
Once we reached the coast, Kal introduced us to two boatmen who owned small wooden boats used for the trip. The sea was calm that morning, so the 15-minute boat ride felt relaxing. We left our shoes behind, carried just our swimwear, snorkeling masks, and waterproof bag.
If you’re planning your own visit, I recommend booking the trip locally instead of online — it’s cheaper (around 2,000–3,000 Vatu per person, including snorkeling gear). And make sure to visit in the morning hours when the sunlight enters the cave perfectly. If I had known earlier, I would’ve brought a GoPro mount or waterproof torch — the colors inside are so surreal that you’ll want to capture every second.
5️⃣ 💰 My Travel Costs & Budget Notes
We spent about 8,000 Vatu ($65 USD) in total for our Blue Cave experience — including transport, guide fee, and a small tip for the boatmen. Entrance to the Blue Cave Tanna Vanuatu itself is around 2,000 Vatu per person, paid directly to the local community that maintains the site.
We also bought a few coconuts and snacks from a nearby stall for around 500 Vatu. There’s no restaurant or shop near the cave, so bringing water and light snacks is a good idea.
In total, visiting the Blue Cave cost us far less than our volcano adventure, but it felt equally rewarding. It’s the perfect low-budget yet high-impact activity on Tanna — especially if you already have a 4×4 arranged.
If you’re staying near Lenakel, most guesthouses will arrange the trip for you. Some even combine the Blue Cave with snorkeling tours or beach picnics. If you’re short on time, a half-day visit is enough; if not, stay longer and enjoy the coastal charm. 💡 Budget tip: Bring cash in small bills. There are no ATMs near the Blue Cave, and many tours require direct local payments.
6️⃣ 💡 Traveliyo Insider Tips
Here’s what I learned from my trip to the Blue Cave Vanuatu — little details that could make your visit smoother:
Go early in the morning. The sunlight hits the cave best between 9 AM and 11 AM.
Wear fins or reef shoes. The underwater rocks at the entrance can be slippery.
Bring a waterproof camera. The reflections are unreal — you’ll regret not capturing them.
If you’re not confident in swimming, tell your guide. They’ll help you with a floatation ring.
Avoid heavy waves. On stormy days, the current near the entrance can be tricky.
Keep your snorkel ready. You’ll need to dive under for just 2–3 seconds at high tide.
Respect the site. It’s sacred to locals — don’t shout or climb on rocks.
Stay longer. The cave empties fast after tours leave — that’s when it feels magical. If you combine the volcano and the cave during your stay in Tanna, you’ll experience both fire and water — two sides of nature’s soul in one island.
7️⃣ 📅 Suggested Itinerary
If you’re planning a short stay on Tanna Island, here’s what our three-day trip looked like — a perfect balance of fire and water:
Day 1: Arrival on Tanna → Check-in near Lenakel → Relax at the beach → Sunset dinner
Day 2: Full day at Mount Yasur Vanuatu Volcano (afternoon hike + night eruption show)
Day 3: Morning visit to the Blue Cave Tanna Vanuatu → Return by noon → Depart to Port Vila
Optional addition for slow travelers:
Stay an extra night near the west coast. Spend your final evening on the beach with locals, enjoying grilled fish and fresh coconuts.
If I were to plan it again, I’d still keep this schedule — the volcano at sunset and the cave at sunrise felt like perfect opposites, complementing each other beautifully.
8️⃣ ✅ Traveliyo Recommendation
Based on our personal visit, our Traveliyo recommendation for first-time travelers to Tanna is simple:
👉 Don’t stop with the volcano — make sure you visit the Blue Cave Vanuatu too.
Both sites show completely different faces of the island. While Mount Yasur gives you adrenaline and awe, the Blue Cave Tanna Vanuatu gives you peace and reflection. Together, they define Tanna’s true identity — an island of fire and light.
For couples, this combination is perfect: one day of excitement, one day of serenity. For solo travelers, the cave offers that quiet moment of connection with nature you’ll remember for life.
If you’re visiting Vanuatu for a short time, allocate at least two nights on Tanna — one for the volcano, and one for the cave.
🌺 Traveliyo’s Tip: The Blue Cave is best visited as part of a local tour rather than a packaged group trip. You’ll save money, meet real islanders, and enjoy the authentic side of Tanna.
9️⃣ 🖋️ Conclusion + CTA
As we sailed back from the Blue Cave, I looked at Taniya — her hair still wet, her smile peaceful. She whispered, “It’s like the island showed us both its moods — wild and gentle.”
I couldn’t have said it better. Tanna had given us a journey through opposites: the rumbling volcano one day, and the silent underwater cathedral the next.
If you ever find yourself standing on the shores of Tanna, remember this — beyond the fiery spectacle of Mount Yasur, the Blue Cave Vanuatu waits quietly, glowing like a hidden gem beneath the sea.
