Sinuhutan Cave in Barangay Onop is a 3-hour mountainous trek. The cave’s name coming from the Hiligaynon term “suhut” or “to walk below,” speaks for itself when entering the site. Tourists can access the cave by passing through its three entrances that leads to three prominent chambers such as the “Jacosi Tab” where a certain species of shrimp is found; the “Female Genital”; and “The Plaza or The Cathedral.” It is said that during the Japanese occupation, the cave became a fortress for the locals living in the area.
