Eco-tourism is pretty popular in South Philippines. One of the nicest waterfalls on Cebu Island can be found 2 hours south-west of Cebu City. The taxi drive takes me through mid sized mountains and hills. While descending to the occidental part of the Island a stunning view of Bohol Island and Dumaguete is offered.
Kawasan Falls are a couple of Miles south of Malboal, a well known dive resort. The falls are spreading over three horizontal levels. It takes about 30 minutes to explore the first 2 levels. The water is showing a very nice deep green and blue coloring. There are two recreation areas where people swim right under the waterfalls. It's amazing to feel the torrential power of the water when swimming into the waterfall. It's cold and strong. Don't underestimate the weight and take a deep breath before you cross the line (if you can make it against the strong flow, anyhow).
