The Wren’s Eggs are located along Blackhead path in the coastal seaside town of Whitehead on the East Antrim coastline.
Blackhead Path is one of many coastal cliff walks along the Islandmagee peninsula including The Gobbins and Skernaghan Point. Blackhead Path leads visitors along a coastal pathway towards Blackhead Lighthouse after climbing the cliffside path through tunnels, and over bridges and steps.
The Wren’s Eggs are actually glacial erratics, large rocks that were transported and deposited in the region by glaciers some 10,000 years ago. These erratics are composed of various rock specimens that differ from the surrounding bedrock. This was a clue for researchers that the rocks were not originally from this region.
The rocks are known locally as the Wren’s Eggs. This is a bit of local humor, as these large rocks could have never come from a small bird such as a wren.
