Unveiling the Legend of the Karoo Mermaids: A Journey Through South Africa's Mystical Landscapes

South Africa is a land of many tales, but few are as captivating as the legend of the mermaids of the Karoo. The Karoo is a vast semi-desert covering much of central and western South Africa, divided into the Groot Karoo (Great Karoo) in the north and the more fertile Klein Karoo (Little Karoo) in the south. It is in these southern valleys that locals have long claimed to glimpse mermaids combing their hair beside mountain rock pools.

An ancient sea beneath the Karoo

There is a grain of deep-time truth behind the legend. The very mountains that cradle the Klein Karoo, the Swartberg, Langeberg and Outeniqua ranges, are built from sandstones and shales that were laid down in shallow coastal seas hundreds of millions of years ago. Around 250 million years ago, the colossal tectonic forces of the Cape Orogeny buckled and lifted those rocks into the folded peaks we see today, leaving the long Little Karoo valley cradled between them. Further north, the Great Karoo was once a vast inland basin often called the “Karoo Sea.” Mountain springs still trickle into rock pools and dissolve out hidden caverns, exactly the kind of watery hideaway a mermaid might call home.

The Cango Caves, at the foot of the Swartberg about 30 kilometres from Oudtshoorn, are a must-visit on any mermaid-seeking adventure along the famous Route 62. Surrounded by dripping stalactites and stalagmites, it is easy to imagine a mermaid sheltering among these ancient formations. Stone tools and other traces of early people, including a Middle Stone Age “Still Bay” point, suggest humans were drawn to this site tens of thousands of years ago.

Rock art at Ezeljagdspoort: mermaids or rain-people?

The Klein Karoo was home to the San (Bushman) hunter-gatherers, and their rock paintings of fish-tailed figures hint that the idea of a Karoo “mermaid” has been around for centuries. The most famous of these can be seen near Ezeljagdspoort, outside Oudtshoorn. It is easy to see why a people living in one of South Africa’s driest regions might weave a water-being into their stories, as a reminder of how precious water is.

Yet the paintings may be richer than the mermaid label suggests. When the linguists Wilhelm Bleek and Lucy Lloyd showed copies of the Ezeljagdspoort image to surviving /Xam San in the 1870s, one informant, /Hanǂkasso, did not see mermaids at all; he spoke of “the rain’s people.” Later researchers such as David Lewis-Williams and Thomas Dowson interpreted the figures as therianthropes, half-human beings painted by shamans in a trance state to call on the rain, while Jeremy Hollmann has suggested they are part-human “swift people.” Far from debunking the legend, these readings deepen it: the Karoo’s water-spirits were bound up with rain-making and survival in a thirsty land.

From an 1875 warning to the 1996 flood

A much-repeated story, recorded around 1875, tells of an old Bushman who warned a local farmer of evil water spirits lurking beneath the pools at Ezeljagdspoort. These spirits, it was said, took the form of a woman who lured passers-by before dragging them to a watery grave. Could this sinister water-woman be another face of the Karoo mermaid?

The legend resurfaced after the devastating Meiringspoort flood of 1996, when some claimed the mermaid had been swept out to sea, then rescued and returned to Oudtshoorn to recover; a local clairvoyant even gave her a name, Eporia. Traditionally the mermaid is a symbol of both destruction and creation, and sailors once read a mermaid sighting as the warning of a coming storm. As an emblem of the feminine life-force, the mermaids of the Karoo could hardly be more fitting. When the rains finally soak the arid plains, the Karoo bursts into life and colour, its succulents flowering in displays that draw photographers and tourists from around the world. Recent years have shown that same dual nature, with heavy floods battering the Klein Karoo again in 2024 and 2026, a reminder that here water still both gives and takes. The legend of the Karoo mermaids endures as a testament to the region’s rich folklore and natural beauty.
