Killarney National Park encompasses over 10,000 hectares of diverse ecosystems including the three Lakes of Killarney: Leane, Muckross, and Upper Lake. It was Ireland's first national park, established in 1932 following the donation of the Muckross Estate to the Irish Free State. The landscape is dominated by the McGillycuddy’s Reeks mountain range, which includes Carrauntoohil, the highest peak in Ireland. The park contains the only remaining herd of native red deer in Ireland, which have occupied the land since the end of the last Ice Age. Its temperate rainforests are home to rare oceanic bryophytes and lichen species that thrive in the high-humidity environment. Muckross House, a 19th-century Victorian mansion, serves as the primary historical anchor within the park boundaries. The park is a designated UNESCO Biosphere Reserve, recognized for its exceptional biological diversity. Glacial erosion shaped the distinct valleys and deep basins of the lake system currently found in the park.
