Dusk settles over the Selangor River and the mangrove line darkens into a living silhouette; then tiny lanterns begin to pulse along the berembang trees, a slow, mesmerising choreography. On this evening tour you move from warm, mineral-rich springs to a waterfront village and finally into the river corridor where Pteroptyx fireflies light up the mangrove canopy.

No flash photography
Flash disrupts firefly communication; use your phone on silent and avoid bright lights during the boat ride.
