Cavan Burren Park is part of the Cuilcagh Lakelands Global Geopark and

is located on a limestone plateau under the shadow of Cuilcagh Mountain. It is widely recognised as one of the finest prehistoric landscapes in Ireland – in a sense this place has stood still in time, surrounded by planted forestry since the 1950s, and now accessible for the public to enjoy and preserve.

Geologically the site is located on limestone bedrock, formed in a shallow tropical sea around 340 million years ago during the Carboniferous period.

Natural geological features such as a relict river bed, associated dolines, and sinkholes across the Lost Valley, further demonstrate how this amazing pre-glacial landscape would have looked. These features can be seen along Trail Two and Trail Three close to the Giant’s Leap.

Then, not that long ago - about 13,000 years - during the last Ice Age, huge sandstone boulders were deposited by glaciers on the limestone bedrock of Cavan Burren. These boulders are known as ‘Glacial Erratics’ and are visible throughout the park. They sit on pedestals of limestone making them distinctive. The landscape you see today was greatly altered by the Ice Age

Another big influence on the landscape here at Cavan Burren Park was the arrival of the first settlers. Around 4,500 BC,  at the beginning of the Neolithic period, it is understood that the first farmers arrived at Burren. They cleared forestry and created settlements where they lived, worshipped, and died. Remains of these settlements are evident from the magnificent archaeological monuments like the Giant’s Grave wedge tomb and the remains of old field walls. 

Geology and archaeology play a huge part in the fabric of Cavan Burren Park. Layer upon layer of prehistory is brought to life through these enigmatic monuments and features.

Visitors can explore the interpretative centre and five remarkable walking trails, showcasing spectacular prehistoric tombs, fascinating geology, and unique stories that make this park an extraordinary environment.
