Where the rest of Ireland is famously, relentlessly green, this corner of County Clare is grey -- thousands of hectares of bare limestone pavement stretching to the Atlantic, cracked into geometric blocks called clints and grikes by millennia of rain dissolving rock. Cromwell's surveyor reportedly dismissed it as a land with "not enough water to drown a man, not enough timber to hang him, not enough earth to bury him." What he missed -- what most people miss at first glance -- is that the Burren's apparent emptiness is an illusion. Between the cracks, Mediterranean and Arctic wildflowers grow side by side, a botanical anomaly found nowhere else on Earth. Underground, vast cave systems hold stalactites among the world's largest. And at the coast, the Cliffs of Moher drop 200 metres straight into the Atlantic in a wall of sandstone and shale.

The rocks beneath the Burren began forming during the Carboniferous period, roughly 340 million years ago, when this part of Ireland lay near the equator beneath a warm tropical sea. Layer upon layer of limestone, sandstone, and siltstone accumulated from the shells and skeletons...

Where the Burren is horizontal and subtle, the cliffs are vertical and overwhelming -- sandstone and shale sea walls that rise over 200 metres at their highest point and extend for roughly eight kilometres along the Clare coa...

Burren and Cliffs of Moher Geopark: Where Flowers Break the Rules

Arctic-alpine plants like mountain avens grow alongside Mediterranean species like dense-flowered orchids, a combination that exists nowhere else. The limestone retains enough heat to support warmth-loving species, while the exposed al...

Burren and Cliffs of Moher Geopark: Geopark and the Community

Photo credit Anna Stavenskaya, CC BY-SA 4.0. The Burren and Cliffs of Moher became a UNESCO Global Geopark in 2011, one of only three in Ireland. The designation grew from a mid-2000s community initiative to manage visitor impact on the fragile karst landscape, led by Clare County Council with support from the Geological Su...
