Hiking Mount Talinis

Mt. Talinis is easily climbed via nature trails that start in Bidjao, Dauin and Apolong, Valencia. Several crater lakes exits: Lake Yagumyum is between Yagumyum Peak and the main peak of Cuernos de Negros; Lake Nailig and Lake Mabilog are crater lakes near the summit. Lake Nailig serves as the main camping ground, with the peak accessible by a 30-minute trek. The summit is heavily forested and mostly covered with fog. The Kaipohan sulfur vents, an area of dead trees and bleached rocks, can be found on the trail to Apolong, Valencia.
