It forms part of the Gorham's Cave complex which has been nominated for UNESCO World Heritage Site status.

[1] The cave was listed as a Palaeontological site and it was protected by law in 2018.

[2] Hyaena Cave, like the other three in the complex, has been gradually filled with sand that has been blown in through the entrance over thousands of years.

These sands remain where they fall and over time they build up to remarkable depths.

In the past the sea was over 4.5 kilometres (2.8 miles) away from the caves whereas it is now very close.
