BACKGROUND
Another notable mountain in Palawan, regarded as Philippine hiking’s “last frontier, is Mt. Thumbpeak, or simply Thumb Peak, in Puerto Princesa. This 1,296 MASL-mountain is visible even from the city proper, and its etymology is obvious, as you can see that its peak is shaped like a fist, with its ‘thumb’ jutting upwards, serving as the very summit of the mountain. Even during the Spanish times, the mountain was known as Pico de Pulgar, which is, literally, ‘Thumb’s Peak’.
Thumbpeak is located within the Iwahig Penal Colony, one of the largest penal farms in the world and one of the most colorful places in Palawan. A permit from Iwahig authorities is needed for a climb, which requires 2-3 days. The initial leg requires seven to nine river crossings, which can be treacherous, and even impossible, in inclement weather. Past the river, a cave serves as the usual campsite; a steeper trail passing by dense forest follows. Here, aggressive limatik can make the hike interesting for climbers. The forest takes around 3 hours to negotiate.
Beyond it, the trees become stunted, and interesting flora emerge, most notably the tropical pitcher plant Nepenthes deaniana, which is found only at the summit of Thumbpeak, at elevations higher than 1100 MASL (see picture). Some bouldering is required at the top, reminiscent of, but of a lesser extent compared to, the assault of Palawan’s high mountains such as Mt. Mantalingajan and Mt. Victoria.
The summit of Thumbpeak is very rewarding: there is a view of South China Sea and Sulu Sea, divided by the narrow island of Palawan; in Palawan itself, to the north one can see Mt. St. Paul, Cleopatra’s Needle, Mt. Airi, Mt. Beaufort, and many other peaks, some nameless; to the south one can see the high mountains of Palawan’s central spine, which will culminate with Mt. Victoria, Sultan Peak, Mt. Gantung, and finally Mt. Mantalingajan, although these are no longer visible. To the east, one can see Puerto Princesa surrounded by two bays, the northern one of which is the famed Honda Bay, with its islands. It is truly a tantalizing sight!
Considering its proximity to Puerto Princesa City, it is a very accessible, quite challenging, and very beautiful hiking destination in Palawan!

SPECIAL CONCERNS
Transportation. There is a jeepney service from Puerto Princesa to Iwahig; but this is not regular. For larger groups, hiring a jeepney may be a better option.
Permits and guides. A permit is required, and guides are recommended. Berto and Bito, the father-and-son guiding duo, are avaialble. One may seek the help of Jasper Camacho (you can search him in Facebook) for assistance. He can help you not only with the permits, but also in the securing of guides (it is his personal advocacy to promote the mountain and provide livelihood for the guides).
Climbing notes. Do follow the advice of your guides regarding the river crossings, which can turn treacherous. Prepare also for the limatik in the forest which are more aggressive than those of Mt. Makiling.
Health and safety. For Palawan hiking, we recommend prophylaxis for malaria. One tablet once a week of Mefloquine (Lariam S) is suggested, as well as vigorous application of insect repellent. The Iwahig Penal Colony, and the mountain, is quite safe and is free from any insurgency or security issues.
