Mount Dulang-Dulang, affectionately known as "D2" among Filipino mountaineers, stands as the Philippines' second-highest peak at approximately 2,941 meters (9,649 feet) above sea level. Located in the Kitanglad Mountain Range in Bukidnon, Mindanao, it is surpassed only by Mount Apo in Davao.

The mountain is enveloped in lush mossy forests, home to a rich array of flora and fauna. Notably, it provides habitat for the endangered Philippine eagle, along with 58 mammal species such as flying lemurs, wild boars, and deer. The surrounding Kitanglad Range Natural Park boasts over 185 species of trees and woody plants.

Mount Dulang-Dulang holds sacred status for the Talaandig tribe of Lantapan. As part of the ancestral domain of the Bukidnon, Higaonon, and Talaandig Indigenous peoples, climbers are often required to participate in traditional rituals to honor the spirits before ascending.

The most accessible route to the summit is via the Bol-ogan Trail in Barangay Songco, Lantapan. The trek typically spans 2 to 3 days, offering adventurers a journey through dense forests, moss-covered trails, and panoramic vistas. For those seeking a more extensive adventure, the D2K Traverse connects Mount Dulang-Dulang with Mount Kitanglad, the fourth-highest peak in the Philippines.

Beyond its ecological and cultural value, Mount Dulang-Dulang serves as a crucial watershed. It feeds several major river systems, including the Maagnao and Alanib Rivers, which are tributaries of the Pulangi River, eventually draining into the Rio Grande de Mindanao.

Travelers from Davao City can reach Bukidnon by bus or private vehicle, with the journey taking approximately 5 to 6 hours. Organized hikes often include transportation arrangements, making it convenient for adventurers to explore this majestic peak.
