Walking Holidays and Outdoor Adventures in Glenveagh National Park

Mountains, Lakes, and a Highland Castle

‍A wild Donegal landscape of glens, forests, and open moorland.

Glenveagh National Park, in the heart of County Donegal, is one of Ireland’s most remote and atmospheric destinations for walking holidays and outdoor adventures. Covering over 16,000 hectares in the Derryveagh Mountains, the park combines rugged peaks, shimmering lakes, deep valleys, and expanses of blanket bog. At its centre lies Glenveagh Castle, a romantic 19th-century mansion on the shores of Lough Veagh, surrounded by celebrated gardens.

Walking here ranges from peaceful lakeside paths and woodland trails to challenging mountain climbs. The park is also home to Ireland’s largest herd of red deer, golden eagles, and vast stretches of unspoiled wilderness.
