Tirad Pass is a mountain pass located in the northern part of the Philippines, specifically in the province of Ilocos Sur. It is historically significant as the site of the Battle of Tirad Pass in 1899, where Filipino revolutionary forces, led by General Gregorio del Pilar, made a valiant stand against American troops during the Philippine-American War. The pass is characterized by its steep terrain and scenic views, making it a popular destination for hikers and history enthusiasts. Today, a monument commemorates the bravery of the Filipino soldiers who fought there, serving as a reminder of the country's struggle for independence.
