Wicklow Mountains National Park spans over 20,000 hectares of upland blanket bog, heath, and deciduous woodland in eastern Ireland. The park contains the Glendalough Valley, home to a 6th-century monastic settlement founded by Saint Kevin. Its landscape is defined by granite mountains, deep glacial valleys, and high-altitude lakes such as Lough Tay and Lough Dan. The terrain serves as a vital watershed for the Dublin region, feeding several major river systems. Visitors can access extensive trail networks, including the long-distance Wicklow Way which traverses the park. The park is managed by the National Parks and Wildlife Service, which maintains visitor centers and educational exhibits. The habitat supports protected species such as the peregrine falcon, merlin, and red grouse. The area's geology is dominated by the Leinster Granite pluton, exposed by erosion over millions of years.
