In the Burren are there are two major rock types; the lighter coloured limestones to the north and east and the darker siltstones, shales and sandstones to the south west. 21 km or 13 miles). Due to remarkable earth movements - plates colliding in the Earth's crust and continental drift - some of that former ocean bed got uplifted onto the Earth's surface and made it to northern latitudes. After refinement, the initiative was extended to 320 farmers over two phases, and another 130 are expected to join a final phase.

Sustainable ecotourism and independent "'Ecotourism Certification" for companies are intended to deal with those conflicting demands.[26].

Archaeological evidence from cave finds of butchered bones have been radiocarbon dated to 33,000 years ago, showing evidence of hunters during the Ice Age. A wonderland, teeming with magical clues about, not only where we come from, but also what the present and future holds. Vole, Red Squirrel, Wood Mouse and Pygmy Shrew populations are also present in this landscape. The combination of features formed by rain and ice are known as a glaciokarst landscape and the Burren is a globally significant example which was awarded Geopark status in 2011. The Burren is most correctly termed a glaciokarst region. This has formed numerous cave systems of which more than 50 kilometres have been mapped.
