The Kings Caves are reached on foot from Blackwaterfoot, it is a pleasant 2 mile walk from the village.   These caves are the largest of a series of seafront caves and are believed to have been a site of early Christian worship.  The caves were formed around 10,000 to 6,000 years ago during an ice age. The current name of the cave is thought to originate from a tale that a Scottish king visited the caves.   Legend also records that Robert the Bruce sought refuge in a cave on his journey to discover new lands, he is said to have been inspired by watching a spider's numerous and ultimately successful attempts to build a web.

 In January 1909, an archaeological dig was conducted within the cave. A 32 foot long trench was dug and examined, but aside from a small bronze ornament and some animal bones, nothing of interest was found, so the dig was halted on the fourth day.
