Named after a river snake called “kasili” because it was believed that they were abundant in this area a long time ago. This 15-feet waterfall with a 20 feet-deep pool is another tourist attraction site especially during Holy Week. It is located 3 kilometers away from Barangay Tula and can be reached only by hike. People visit the falls for picnics, or an outdoor activity with families and friends. This is also the spot where mountain trail hikers plying Tula-Lake Danao route stay. After an overnight stay at Lake Danao, during their mountain trail hike, they stop over for lunch before they depart for Barangay Tula.
