Explore Donegal's only National Park — 170,000 acres of mountain, lake and ancient woodland — crowned by a turreted Victorian castle whose interiors were styled by one of Hollywood's greatest designers. A private guide brings every layer alive.
What to expect
The route north from Killybegs reveals Donegal's glacier-carved heartland before arriving at Glenveagh. A park shuttle runs to the castle on Lough Veagh, where your guide leads you through the Victorian trophy rooms and the formal gardens planted by celebrity owner Henry McIlhenny. After the castle, the tour continues to Errigal Mountain's base for a dramatic photo stop. The drive back through the Derryveagh Mountains at golden hour is simply stunning.
Good to know
Full day — approximately 8 hours. Pre-book the castle entry ticket at heritageireland.ie (EUR 6 adult) to avoid shuttle queues. Comfortable walking shoes recommended for garden and parkland paths. A packed luxury picnic can be arranged on request through the operator.
