1) Son Doong, Vietnam

Only recently discovered in Vietnam’s Quang Binh Province, Son Doong has been named the world’s largest cave. This natural wonder can be reached by trekking across the wild jungle of UNESCO World Heritage Phang Nha Ke Bang National Park and by crossing river valleys.

2) Chapada Diamantina, Brazil

The lesser visited region of Brazil’s interior, Chapada Diamantina National Park, is made up of table-top mountains, vast plains, waterfalls, crystal-clear streams and an astonishing system of caves that conceal underground rivers where gold and diamonds were once mined.

Caverns of vibrant blue pools and waterfalls remain, with rivers that sank through erosion. The caves are especially noted for their rare stalagmite formations and the important discovery of extinct animals’ bones.

4) Stone Hole, South Africa

On the Atlantic Coast that stretches southwest of Cape Town, the Whale Coast is best known for its marine life and the white sand beaches that are backed by mountains, valleys and nature reserves. Between two bays, Grootbos Private Reserve covers a great expanse of 2,500 hectares. Here, archaeological excursions can be taken to the huge limestone caves that have were formed millions of years ago.

Named Klipgat Cave, meaning stone hole, due to an opening that offers panoramic views of the bay, the site is important for its wealth of pottery, stone and bone artifacts, which are remnants of the Stone Age people that lived there.

Just outside the peaceful lakeside town of Pindaya in Myanmar, this vast limestone ridge consists of three caves, only one of which can be explored – its entrances signified by a large bronze bell and pagoda.

The enormous cavern is a renowned pilgrimage site, containing an incredible 8,000 images and gilded statues of Buddha, with small chambers for the pilgrims to meditate in. The surrounding hills are also prime hiking country.

At the southern tip of Chile, the Patagonian region of Aisen is a vast expanse of dense evergreen forest and ice fields, immense fjords and deep blue glacial lakes. Here, at the centre of America’s second largest lake General Carrera, you’ll find Marble Chapel and Marble Cathedral.

This group of marble caverns, columns and tunnels has been carved by wave action over more than 6,000 years. Kayak through the sculpted rock formations as they reflect down on the crystal clear water of the lake.

Dripstones, Waitomo Caves, New Zealand

8) Waitomo Caves, New Zealand

This limestone labyrinth of underground rivers and sinkholes near Auckland can be traversed by boat or on foot, but the most adventurous can try blackwater rafting in which you crawl, swim and float through the caves on a rubber tube – you can even abseil or zip-line through the caverns if you dare.


By far their most famous feature, however, are the startlingly beautiful glow worms that fill the caves with their microscopic star-like radiance. A New Zealand must-see for adventure seekers and lovers of natural beauty alike.

Spectacular hikes through the cliffs and hills of this ancient region lead to churches hewn into the rock, some even older than the 12th century churches of Labilela.

Take the opportunity to visit Tigray’s capital, Mek’ele, from which you can head off on an intrepid exploration of the striking Danakil Depression.

Skocjan Caves, Natural Heritage Site in Slovenia

11) Škocjan Caves, Slovenia

Whilst the Postonja caves are one of Slovenia’s most popular tourist sites (and quite rightly so), the Škocjan Caves are also a must-see, and far less crowded. Carved out by the Reka River, the caves stretch for 6km before ending in a sump known as the Dead Lake.

From stunning stalactites and stalagmites to flowstones that look like snowdrifts, jungles of exotic dripstones and a dizzying 50m high bridge, these caves are full of sights to marvel at.

These stunning 2km caves are draped in lush greenery on the outside, whilst the inside makes for some great exploring and is home to a colony of wild bats.

13) The Blue Grotto, Italy

This ethereal sea cave on the picturesque Italian island of Capri gets its name from the water inside, a crystalline azure blue which sparkles and glows in the light. Entering the cave is half the adventure, as its the low height of the entrance means you must lie flat on the bottom of a small four-person row boat to pass through.

For the same reason, entrance can only be achieved when tides are low and the sea calm. The shining blue of the cave is created by sunlight passing through an underwater cavity and shining through the seawater, which in turn creates a blue reflection that lights up the whole cavern.

14) Ali Barbour's Cave Restaurant, Kenya

For a completely different cave experience, head to Ali Barbour’s Cave Restaurant in Kenya’s Diani Beach. The cave is thought to be between 120,000 and 180,000 years old – though the restaurant has only been there for the last 30.
