Glenveagh
Park Irish national park with 19th-century castle and gardens
Glenveagh in County Donegal centers on a 19th-century castle, walled gardens and Glenveagh National Park’s lakes and mountains. Visitors hike trails, watch red deer, and explore the formal gardens beside remote bog and glen scenery.
Glenveagh is a national park and estate in County Donegal, Ireland, centred on Lough Veagh and the surrounding Derryveagh Mountains. The area includes a prominent castellated house known as Glenveagh Castle and extensive gardens set within a remote upland landscape.
Key attractions within the park are the castle and its restored walled garden, the mountain and shore trails around Lough Veagh, and opportunities for wildlife viewing across woodland and moorland. The park’s scale and terrain make it a destination for hiking and nature photography.
The estate and grounds were developed in the 19th century and later incorporated into the national park, which preserves both the cultural landscape and natural habitats. Conservation and visitor facilities are managed to balance public access with habitat protection.
Glenveagh lies in north-west County Donegal in the province of Ulster, set among rugged hills and freshwater lakes. The park is reached by regional roads from nearby towns in Donegal and is one of the more remote protected areas on Ireland’s northwest coast.
