Situated within the stunning Bothongo Rhino & Lion Nature Reserve in the heart of the UNESCO World Heritage-listed Cradle of Humankind, the Bothongo WonderCave invites visitors to descend into one of South Africa's most breathtaking underground wonders.

This vast, single-chamber cave offers an unforgettable experience with no crawling required – just awe-inspiring natural beauty. As a both a beautiful and educational hidden gem, here are five things you probably didn’t know about the Bothongo WonderCave:

A Geological Masterpiece Millions of Years in the Making 

The Bothongo WonderCave's story begins in ancient seas, where layers of limestone were deposited over time. Over 5 to 10 million years, mineral-rich water slowly dissolved and redeposited the rock, sculpting the enormous chamber we see today.

Discovered by Italian miners in 1898 during limestone quarrying, around 15% of its calcite formations were extracted for uses including toothpaste, cement, and even gold smelting processes. Mining halted around 1902 (partly due to the Second Boer War), preserving the  remaining 85% of this pristine underground wonder for future generations.

South Africa’s Third-Largest Cave Chamber

Spanning an impressive 46,000 m², the Bothongo WonderCave ranks as the country's third-largest single cave chamber, behind only the iconic Cango Caves and Sudwala Caves. What sets it apart is its accessibility: the entire space is walkable, with towering ceilings and wide paths that create a cathedral-like atmosphere. This means no tight squeezes or caving gear needed. 

Living Formations That Continue to Grow 

The cave is home to dramatic stalactites and stalagmites, some soaring up to 15 metres high, with around 14 major formations still actively growing thanks to ongoing dripstone deposition.

Visitors can explore unique features like shimmering rimstone pools, delicate cave pearls, popcorn textures, straw stalactites, and whimsical mushroom formations. These "living stones" are a vivid reminder that the cave remains a dynamic natural work in progress.

Surprisingly Easy and Comfortable Access 

Reaching the cave floor is effortless and family-friendly. Visitors first descend 87 stairs at a 45° angle (dropping 22 metres below ground), followed by a smooth elevator ride that carries you an additional 18 metres into the heart of the chamber. Guided tours, lasting about 45 minutes, run regularly, with knowledgeable guides bringing the cave's history and geology to life.

Magical Echoes

Thanks to its massive single chamber and almost total lack of external noise, plus having only one entrance that keeps bats (and their squeaks) away, the Bothongo WonderCave is remarkably quiet when you first step in. The only sound you'll often hear is the gentle, rhythmic drip of mineral-rich water continuing to sculpt the living formations.

However, try clapping your hands or speaking just a little louder and the vast, smooth limestone walls create a surprisingly clear, resonant echo that bounces around the space, turning even a soft whisper into a lingering sound. 

Tip: Ask your guide to demonstrate this acoustic magic to show how the cave "answers back”. This means a trip underground isn't just visually stunning, it's an immersive sensory experience too!

The Bothongo WonderCave is open to visitors as part of the Bothongo Rhino & Lion Nature Reserve experience. For the best visit, wear comfortable, non-slip shoes, and note that flash photography may be restricted in certain areas.
