Towering over Clew Bay near Westport, Croagh Patrick (764m/2,507ft) is Ireland’s holiest mountain and a place of pilgrimage for over 1,500 years. Known as "The Reek," this iconic peak is linked to St. Patrick, who is said to have fasted at its summit for 40 days. Today, thousands of pilgrims and hikers climb its steep, rocky slopes—especially on Reek Sunday (the last Sunday in July)—for spiritual reflection, breathtaking views, and a true test of endurance. Wear sturdy hiking boots, bring layers (weather changes fast!), and consider a walking stick for the descent. Whether for faith, adventure, or stunning landscapes, climbing Croagh Patrick is a quintessential Mayo experience.
