The soft gurgle when the paddle dips into the river, gliding the sampan along. The song of a hundred crickets singing as if their hearts would burst in joy. The anticipation causing tingles up your spine. The boat takes a corner, and there it is. A thousand lights twinkling in the trees. A light floats towards you, and you see it. A firefly. Allow NCR Travel to introduce you to one of the most breathtaking natural wonders in the world, the fireflies of Kuala Selangor.
