Firefly Watching is another exciting experience in Palawan, taking place just before dusk, this tour allows you to get closer to nature and, in particular, the dazzling and flickering insects known as "Fireflies" or "Lighting Bugs." PLEASE NOTE: Absolutely no flash photography, as this will disturb the Fireflies causing them to leave the immediate area. Take this chance to be closer to nature and enjoy the beautiful, peaceful and calm river, with the nearby trees lit up, just like Christmas Trees, by the Fireflies. Fireflies live in abundance amongst the mangroves and trees, which are entirely situated along the banks of the Sicsican and Iwahig Rivers. This location is ideal as it is away from the light pollution experienced in the city.
