Begin with 4pm pickup at your hotel in Kuching, then transfer to Sarawak Boat Club, where your cruise departs. Board a boat for the trip along the shoreline, making your way to the mouth of the Santubong River—watch for Irrawaddy dolphins along this stretch, as they gather to feed in the Santubong River estuary.
Turn into the river, which is sheltered by thick stands of mangroves, then look for the proboscis monkeys that linger in the treetops: you can’t miss their distinctive, long-nosed silhouettes in the evening light. Crocodiles begin to stir at dusk, and you can spot them by shining a flashlight at the edge of the river, where their eyes will shine just above the surface of the water.
As you go deeper into the trees, fireflies begin their nightly display, lighting up and blinking as they cluster around the mangroves. After their twinkling subsides, begin the return trip to Sarawak Boat Club. This tour concludes with drop-off at your Kuching hotel.
