We've been there last Dec 2012 & I must say this mountain is a majestic one. It is a part of protected area. we did a day hike but it took us 7hrs Up - 7hrs Down from 6am ascend & 10pm back to jump off. the best itinerary would be an overnight camping. It showcased beautiful rivers, thick forest w/ different and rich variety of flora & fauna. Our guide pointed us a small ground orchid w/c is still unnamed and unidentified according to foreign Scientists who scanned the area on earlier month. On the summit, there are diff. varieties of Nepenthes (Pitcher plants) hanging on and crawling under bonsai trees. And of course, a 360 view of nearby mountains, west coast of the island, the view of whole city of Puerto Princesa, Iwahig River down the other side. The evening on our way down, the trail was full of fireflies light up our way like in fantasies. What a joyful experience we had that day. Since the place is a protected area, please secure a permit ahead of time (this can be made by your contact guide), and take local guide with you.
