Glenveagh National Park covers 16,000 hectares in the Derryveagh Mountains of northwest Donegal. It is Ireland's second largest national park and one of the least visited per capita, which makes it an attractive option for anyone trying to get away from the main tourist circuits. The park encompasses Lough Veagh — a 7 km glacial lake enclosed by mountains — and the castle that sits at its southern end.
Glenveagh Castle was built between 1867 and 1873 by John George Adair, a land speculator who in 1861 evicted 244 tenants from the estate in winter, with no alternative accommodation arranged — one of the worst mass evictions in Irish history. The castle subsequently passed through several owners, including Henry McIlhenny, the American millionaire and art collector who transformed the gardens and entertained extensively here from the 1930s to 1970s. McIlhenny donated the estate to the Irish state in 1983. The gardens, which blend formal and informal planting styles and include an Italian garden and a pleasure garden, are among the finest in Ireland.
The park is also one of the strongholds of the golden eagle in Ireland — reintroduced in 2001 after a 100-year absence — and has a significant red deer population. The visitor centre at the park entrance has a café and interpretive displays. A shuttle bus runs to the castle from the visitor centre (4 km); walkers can take the lakeshore trail instead.
Highlights
- Lough Veagh — a 7 km glacial lake enclosed by the Derryveagh Mountains, accessible only within the park
- Glenveagh Castle gardens are among the finest in Ireland — a mix of formal terraces and informal woodland planting
- Golden eagles were reintroduced here in 2001 and the park is now one of their main Irish strongholds
- The park's history includes one of the worst mass evictions of the Famine era — the visitor centre tells the full story
- Red deer are common in the park — the lakeshore trail is a reliable place to see them in the early morning
Good to know
- →Take the lakeshore walk (4 km each way) rather than the shuttle bus if you have time — the views across the lough are better on foot.
- →The gardens at the castle are the highlight for most visitors. Allow 45 minutes minimum for them.
- →The park is very quiet outside July and August — spring and autumn are ideal for wildlife and photography.
- →Dunlewey Lough and the deserted village at the foot of Errigal mountain are worth adding to a Donegal day.
- →There is no café at the castle itself — the visitor centre near the car park has a small tearoom. Churchill village has nothing; bring your own food for longer walks.
Best Time to Visit
May–Jun for rhododendron bloom in the castle gardens; Aug for the start of the red deer rut. Access to the castle is by shuttle bus from the visitor centre — check the last bus time before you plan your walk.
