Situated in Talim Island, the largest inland island in Luzon that is located in Laguna Lake which is the largest lake in South East Asia. Mt. Tagapo is the highest peak in Talim Island, the journey includes an hour of boat ride from Brgy. Janosa in Binangonan, Rizal to the island of Talim. It was known to locals as "Mt. Susong Dalaga" and was also mentioned by Jose Rizal in his diary dated May 8, 1882 (Monday), [Aboard the Salvadora: Calamba to Barcelona]  "Mt Susong Dalaga of Talim Island" because it's slopes resembles a maiden's breast.

It may not be as high compared to other mountains which stands at only 1437 ft. above sea level but it rewards the climbers with a spectacular view of the Laguna Bay and the surrounding fishing villages. 

The trail that leads to the summit is predominantly composed of bamboo which most of the locals on the island used to make furniture, toothpicks, and charcoals to earn for their living. Thus, the name Mt. Tagapo originated from the word “Taga” which means “to chop” which refers to the activities of chopping bamboos that are found throughout the area. The last part of the trail is composed of open grassland slope that resembles the background picture of "Windows XP" which is more or less 200 ft. that has some steep portion but still manageable even for beginners.
