Last updated: 3 March 2026

Overview

Glenveagh National Park lies in the heart of County Donegal, nestled among the Derryveagh Mountains. Covering roughly 170 km² (16,000 ha), the park encompasses the U‑shaped glen of Lough Veagh, rugged mountain peaks, blanket bogs and ancient oak woodlands. Its remote location – about 30 minutes north‑west of Letterkenny – gives it a wild, untouched feel, while the Victorian‑style Glenveagh Castle and its exotic gardens provide a striking contrast of cultivated beauty.

History

The estate that became Glenveagh was assembled in the 1850s by Captain John George Adair, an Anglo‑Irish businessman who made his fortune in the United States. Adair’s ambition was to create a hunting retreat that could rival Balmoral, but his ruthless eviction of 44 families during the 1861 famine earned him the nickname Black Jack and left a scar in local memory. After his death in 1885, his American wife Cornelia Adair expanded the gardens, introducing exotic shrubs and a glasshouse.

In 1929 the estate passed to Harvard archaeologist Arthur Kingsley Porter, whose mysterious disappearance in 1933 added a layer of intrigue. The final private owner, Henry Plumer McIlhenny of Philadelphia, bought the property in 1937, enriched the gardens further and, in the 1970s, bequeathed the castle and grounds to the Irish state. The National Parks and Wildlife Service officially opened Glenveagh National Park in 1984, making it the only national park in Ulster.

What to See & Do

Wildlife

  • Red deer – the park hosts Ireland’s largest herd; they roam the high ground in summer and descend to the valleys in winter.
  • Golden eagles – re‑introduced in 2000; sightings are rare but possible, especially in the upland areas.
  • Birdlife – meadow pipit, stonechat, grouse, raven, peregrine, merlin, siskin, treecreeper, wood warbler and crossbill are common. Peat‑bogs support curlew, dunlin and migratory geese.

Glenveagh Castle & Gardens

The castellated mansion, built between 1867‑1873, sits on the shores of Lough Veagh. Self‑guided tours run Tuesday, Wednesday, Thursday, Saturday and Sunday (closed Monday, Friday and bank‑holiday Mondays). Highlights include the drawing‑room, music room, library and the outdoor pool beneath a tower.

The castle gardens span over 11 ha and are divided into the Pleasure Gardens, Walled Garden, Gothic Orangery, Italian Terrace and Tuscan Garden. Rhododendrons blaze in May‑June, while the Walled Garden offers dramatic autumn colour.
