A remote Victorian castle perched on Lough Veagh, surrounded by 16,000 hectares of rugged Derryveagh mountain wilderness — one of Ireland's finest national parks.
This 19th-century granite castle, built by John George Adair and later home to Henry McIlhenny, offers self-guided tours Tuesday–Sunday. Rooms are furnished as they were in the early 20th century. Last entry 16:45. Closed Mondays and Fridays (except bank holidays).
Started in the 1890s by Cornelia Adair and later enriched by Henry McIlhenny, the walled garden and surrounding ornamental grounds burst with exotic trees, shrubs and statuary — a startling contrast to the wild bog and mountain beyond.
This 3.5km moderate walk runs from the Visitor Centre along the shore of Lough Veagh, through pine woods and blanket bog, ending at the Castle Gardens. Return by shuttle bus (ticket from Castle reception). Allow 40 minutes.
An 8km extension beyond the Castle through the Derryveagh Mountains. Mostly flat dirt/gravel road that rises gently over the final 3km. Strenuous — arrange a pick-up or use the Walkers Bus (Saturdays & Sundays, €5).
A short 1km loop behind the Castle, steep in parts, leading to superb panoramic views over Lough Veagh, the Castle and the surrounding uplands. About 35 minutes at a leisurely pace.
Glenveagh is a core conservation area: look for reintroduced golden eagles, peregrine falcons, red deer, and the rare red-throated diver. Dawn chorus in May is exceptional. The Derrylahan Nature Trail (2km loop, easy) is a good starting point.
The Visitor Centre (open 9:15–17:30) has free daily exhibitions on Ireland's national parks, the golden eagle reintroduction, and the Derryveagh evictions. Staff are on hand for walking advice and nature information.
