The Top 6 Natural Wonders in Vanuatu

We hinted at it, and you probably already know it, but the highly active volcano of Mt Yasur is a natural wonder that's on most visitors' bucket lists.

Known as the "Lighthouse of the Pacific" for its nearly continuous Strombolian eruptions, which have been observed, at least in Western history, since Captain Cook in 1774. It reaches 361 m (1,184 ft) high with a 400 m (1,312 ft) wide crater.

Mt Yasur offers one of the world's most accessible active volcano experiences. Visitors can reach the crater rim through several options: an easy-to-moderate hike from the southern gate entrance, a longer hike from Lamakara (John Frum Cargo Cult) Village on its northern flanks, or guided 4WD tours that take you (almost) to the top. For the more adventurous, ashboarding down the side of the volcano is also possible.

Needless to say, there's nothing like the feeling of the raw power of the earth beneath your feet as you approach the crater rim.

This experience is best done before sunrise or before sunset, when you'll witness the mesmerising red glow of lava against the dark sky.

Over on Espiritu Santo, more commonly known as Santo, the island is awash in crystal-clear swimming grottos called "blue holes". Although it's hard to just give one example, the Riri Blue Hole is as magical as any!

This stunning natural wonder offers a magical journey along the translucent Ri Ri River, where unbelievably crystal-clear waters transition from emerald green to brilliant azure blue as you paddle deeper into the jungle.

The adventure begins with a peaceful 45-minute paddle or outrigger canoe ride through mangrove-lined waterways that feel like a portal to another world. Unlike other blue holes across Santo, the water here maintains exceptional clarity throughout the journey, allowing you to see straight to the bottom despite its considerable depth.

Upon arrival, you'll find yourself surrounded by lush jungle with platforms for easy access, plus facilities including bathrooms and changing areas thoughtfully provided by locals. The blue hole itself features a swing rope for those seeking a bit of adventure, though the overall atmosphere encourages languid soaks, a little snorkelling if you have the gear, and a moment to embrace the beauty of this hidden grove.

Everything on Tanna might be overshadowed by Mt Yasur, but the Giant Banyan Tree is an impressive site that's well worth scouting out.

This ancient giant measures an incredible 80 metres (262 ft) high and spans over 100 metres (328 ft) wide, larger than a football field, and continues to grow even today.

The tree's sheer scale becomes apparent as you walk through tunnels carved between its hundreds of aerial roots, which drop like natural pillars from the sprawling canopy above. Legend has it that when Captain Cook visited Tanna in 1774, this remarkable tree was already enormous (check out more fun tidbits in our 20 Fun Facts About Vanuatu LINK#TT065).

From the scenic viewpoint, you'll gaze down upon the vast crown before descending steps to explore the base, where dappled sunlight filters through the intricate maze of roots and leaves. Local guides from the village enhance the experience, sharing insights about this living cathedral that has witnessed centuries of island history!

Vanuatu has plenty of amazing waterfalls. However, many, especially on the main island of Efate, have all sorts of structures built around them to improve accessibility while perhaps taking a little away from the feeling of the truly "natural" experience.

On the lesser-visited island of Malekula LINK#D035, waterfalls like those on the Losinwei Cascades Walk certainly don't have that problem.

This gorgeous half-day hike whisks you into the misty heart of central Malekula, where your local guide will lead you through forest trails that feel like stepping into a fairy tale. We're talking delicate orchids clinging to ancient trees and vibrant flowering irises that'll have you stopping every few metres for photos.

The star of the show is Losinwei Waterfall, where you can dive into the crystal-clear pool beneath the cascading waters. Feeling adventurous? Scramble up the rock face to discover hidden limestone pools that most visitors never even know exist.

After working up a sweat on the trail, you'll have plenty of time to laze about in this natural paradise before making the easy stroll back to Losinwei Beach.

Unlike the hikes Malekula is famous for, you don't need to pack like you're conquering Everest to experience Malekula's incredible trekking, as this walk proves that sometimes the best adventures come in small packages.

Again, picking a single snorkel spot to emphasise the underwater richness of Vanuatu is not easy feet. While most are drawn to the World War Two wrecks around the islands, pure nature can be enjoyed at sites like Top Rock.

The professional setup impresses from the start, with excellent signage, a welcoming entrance and hedged pathways guiding you to this stunning limestone cliff location.

Descend through a large cavern that provides easy sea access for snorkellers of all experience levels. The exceptional water clarity makes spotting small tropical fish effortless, while lucky visitors might encounter turtles gliding through the coral gardens.

After your underwater adventure, savour a delicious lunch "with a view" atop the cliff, where you can admire breathtaking panoramas of the neighbouring Nguna and Pele islands while supporting local vendors.

It's also possible to visit the site via organised tours with Yumi Tours from Port Vila.

Another natural stunner on Tanna, Blue Cave begs to be explored with its sunbeams lighting up the blue waters inside!

The journey to what locals call Lemnap Cave begins with a spectacular boat ride along the dramatic limestone coastline. You'll glide past ancient caves and secluded beaches that feel like they've been untouched for centuries.

Reaching the cave's interior, however, is where the real adventure begins. It requires a short underwater swim of about half a metre. But once you surface in the cave, you'll find yourself in nature's own cathedral.

The grotto stretches 60 m (197 ft) across with a shaft of sunlight that filters through a 5 m (16 ft) opening in the roof above.

The ethereal blue glow that gives the cave its name creates an atmosphere that's simply otherworldly.

Needless to say, you'll need to be comfortable swimming and putting your head underwater for this experience.

The cave is only accessible through organised tours with operators like White Grass Ocean Resort & Spa, Rockwater Resort, Tanna Volcano Transfers & Tours and Blue Cave Tanna Tours & Cafe.
