Firefly watching takes place in Iwahig River, one of the biggest and scenic rivers in Puerto Princesa. It is a Community Based Sustainable Tourism Program, the beneficiaries of which are the community people themselves so a tour here is in a way an investment to a community to take care of their place even more.
Open your eyes to a different world of lighters glittering numerous mangrove trees somehow resembling Christmas trees in the darkest of night, only their lights are not powered by electricity but by freshest of oxygen intake as explained by the local guide. It is truly a sight to behold one visitor of Puerto Princesa shouldn’t miss.
As additional to the tour, boatmen include the discussion of constellations visible in the sky which he points out using his laser lights.
