Rangko Cave has been discovered just a few years ago. We will approach the village of Rangko and use the speedboat to disembark you to the shoreline. Then there is a 15 minutes’ walk to the entrance. The sunrays will be the unique natural illumination of this cavity. Your eyes will need a few minutes to accommodate to the darkness and then you will notice many stalactites and below a natural dreamlike pond where you can swim. The water is fresh and crystal clear. This is indeed a spectacular natural pool.
