This sandstone formation developed roughly 400 million years ago when the region lay beneath shallow sea water. The rock originated during a period when the area hosted a marine ecosystem with coral structures.
Estonian folklore mentions a mythical smith who worked inside the caves of Kallaste outcrop, crafting weapons for local inhabitants during ancient times.
The site is easily accessed on foot and offers a straightforward walk with views of the various rock faces. Visitors should be prepared for uneven ground and wear sturdy footwear.
