The castle was inspired by the design of Balmoral Castle in Scotland.
The estate was once owned by Henry McIlhenny, who donated the property to the Irish state in 1981.
It contains Ireland's only population of golden eagles after they were reintroduced to the park in 2000.
The gardens include a rare collection of plants from the southern hemisphere, particularly South America and Tasmania, thriving due to the local microclimate.
The estate was the site of the infamous 'Derryveagh Evictions' of 1861, where 244 tenants were evicted by John George Adair.
Glenveagh National Park is a 170-square-kilometer wilderness area in County Donegal, centered around the Derryveagh Mountains and Lough Veagh. The estate features the 19th-century Glenveagh Castle, built by John George Adair, surrounded by one of Ireland's largest and most significant gardens. The park contains the largest herd of red deer in Ireland. Its landscape is defined by rugged mountainous terrain, blanket bogs, and ancient oak woodlands. The park is part of the larger network of protected Irish National Parks under the management of the National Parks and Wildlife Service. The visitor center serves as the main gateway for education on the local ecology and history of the estate. The terrain is largely uncultivated, offering a habitat for golden eagles, which were successfully reintroduced to the area. Trails vary from accessible paths near the castle to strenuous mountain climbs.
