About Aillwee

Did You Know?

• •The name is derived from the Irish Aill Bhuí, meaning 'yellow cliff,' referring to the distinctive pale colouring of the limestone escarpment on its northern flank which stands out against the surrounding grey landscape.
• •While the hill is widely known for the show cave system hidden beneath its slopes, the surface remains a prime example of a 'glaciokarst' landscape, where the limestone has been scoured by ice and then weathered into deep fissures called grykes.
• •The summit offers a clear, earned view across the Burren’s unique moonscape toward the high plateau of Black Head to the west and the Connemara mountains far across the water to the north.
• •The terraced slopes act as a natural rock garden; the deep, sheltered grykes create a microclimate that allows Mediterranean-Atlantic plants to grow alongside arctic-alpine species.
• •Despite its modest elevation, the terrain demands careful footwork; the limestone pavement is a maze of ankle-trapping gaps that seem specifically designed to reclaim any dropped loose change or walking pole tips.
