The best way to visit is to book a stay through one of the jungle lodges operating on the Kinabatangan River. They will take care of your transportation from Sandakan or Sepilok.
I thought the Sungai Kinabatangan floodplain was a fascinating place to be. Teeming with a variety of flora and fauna, parts of the floodplain have recently come under protection with the WWFÃ¢â‚¬â„¢s urging, and the local people are proud and excited to help safeguard their natural haven. Sightings of proboscis monkeys, macaques, monitor lizards, civets, hornbills, and kingfishers are common and with a bit of luck one can see orangutans and elephants.
