A large cascade of seemingly reddish water from the main Pulangbato Falls in Pulangtubig , Valencia , finds its way into some unique shaped falls all the way down the mountain.

Located in Dawis, Bayawan, Niludhan Falls is one of Negros Oriental’s hidden gems.

A half day trek up Mt. Talinis in Valencia brings you to either one of the mirror clear lakes in the Mt. Talinis area where you may camp, swim or catch carp, tilapia and other fish in the lake surrounded by trees.
