Kawasan is disgusting nowadays. Four or five years back is was gorgeous - now not so much. They actually have karaoke playing at the falls area. There was also a problem with the canyoneering - politics and greed have ruined it and you can't do the whole run anymore.
Thankfully, we discovered Aguinid Falls later that day. Aguinid is south of Kawasan and is absolutely stunning. It's a series of waterfalls that you wade, walk and climb through over the course of a few kilometers. Super nice adventure!!
Here's a comprehensive blog entry someone wrote up on Aguinid.
