Glide through mangrove tunnels at dusk to watch fireflies puncture the night—an intimate, low-impact wildlife cruise from Puerto Princesa. This four-hour tour pairs a riverside dinner with guided observation in a protected mangrove corridor.

Dusk settles over the mangroves and the boat slips away from the low shoreline, engines whispering as the river narrows. Lanterns on the bank blink like distant beacons; then, as the night deepens, the trees begin to sparkle—hundreds of fireflies punctuating the dark with brief, electric signatures. The experience is quiet and concentrated: a slow drift, a guide’s soft voice, and the river itself seeming to press you forward.

Wildlife
History
The Iwahig area developed around river transport and small fishing settlements; nearby historical sites include communities connected to the Iwahig Penal Colony established under American colonial administration.
Conservation
The river and mangrove corridor are sensitive habitats; operators limit lights, control boat speed, and use designated routes to reduce disturbance to breeding fireflies and other wildlife.
Reserve your spot on the Joiners Firefly Watching Tour today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
No Flash Photography
Avoid flash—bright light disrupts firefly signaling and frustrates viewing; use a camera with low-light capability or enjoy the display with your eyes.
Mosquito Protection
Wear long sleeves and bring insect repellent; mangrove rivers are mosquito habitat after dark.
Bring a Red-Filtered Headlamp
Use a red-filtered light for moving around the boat to preserve night vision and avoid startling insects.
Cash for Gratuities
Carry small bills for guide and boat crew tips or incidental purchases—remote pickup points may not accept cards.
