The last time we visit Ilagan Sanctuary was April 22, 2012. A wonderful experience with new people.
About two hours of walking before reaching the Pinzal Falls but most of us enjoy the scenic beauty of the place. It's definitely a commendable visit for you guys, despite the area leading to the falls do not have yet any concrete paths for an easy reach in a matter of minutes.
Find time to visit again, maybe the next summer of 2013. Enjoy enjoy and enjoy. :D
