Ireland’s national parks protect a remarkable variety of landscapes – from the glacial lakes and oakwoods of Killarney to the limestone pavements of the Burren, the rugged mountains of Donegal and the dark skies of Mayo, along with major recent additions including Ireland’s first marine national park in Kerry and the historic Boyne Valley landscape. Managed by the National Parks and Wildlife Service (NPWS), they cover diverse terrestrial, coastal and marine ecosystems and offer endless opportunities for walking, wildlife watching and heritage discovery.
