Guided Mountain Walks

Explore Ireland’s Most Stunning Peaks with Expert Local Knowledge

Wicklow Mountains

Ireland’s most iconic mountain range, right on Dublin’s doorstep. The Wicklow Mountains offer dramatic landscapes from Glenmacnass waterfall to Leinster’s highest peak, Lugnaquilla. These are mountains with character: heart shaped Lough Ouler, sweeping plateaus, and trails used by Ireland’s elite Army Ranger Wing for training. Whether you’re climbing your first major summit or tackling a challenging 22km traverse, Wicklow delivers big mountain days with some of the country’s most rewarding views.

Blackstairs Mountains

While most hikers head to Wicklow, the Blackstairs stay quietly spectacular. These peaks along the Wexford and Carlow border offer genuine remoteness and sweeping coastal views without the crowds. Stand beside Mount Leinster’s distinctive 122 meter mast and you’ll likely have the summit to yourself. From accessible first summits to challenging ridge traverses, the Blackstairs give you authentic mountain experiences in one of Ireland’s most underrated ranges.

Comeragh Mountains

The Comeraghs are home to some of Ireland’s most spectacular corrie lakes, carved by ancient glaciers and set in truly majestic surroundings. Starting from the historic town of Clonmel, these Tipperary peaks offer everything from gentle introductory walks to serious mountain challenges. Whether you’re exploring the glacial valleys or tackling the full plateau traverse with over a kilometre of climbing and views stretching to the Waterford coast, the Comeraghs deliver genuine mountain beauty and rewarding days out.

Sunrise and sunset

There’s something magical about watching the sun rise or set from a mountain summit. These exclusive experiences take you into the mountains in darkness, where you’ll witness Ireland’s peaks transformed by golden light and still morning air or evening calm. From Lugnaquilla’s sunset over Wicklow to sunrise above the Wexford coast from the Blackstairs, these walks offer moments most people never experience. Limited to six participants for an intimate mountain experience, you’ll need a headtorch, warm layers, and a sense of adventure.
