Recently we spent a long day visiting this Dayak cultural gem, and can highly recommend it! For the slow traveller, who could choose to sleep in the longhouse and tune into the pace and character of the place over 3 days, or for those having time only for a quick day trip from Palangka Raya.
The village of Tumbang (or confluence of rivers) Malahoi is sited where the Malahoi River joins the much larger Rungan River, which is in turn a tributary of the Kahayan River. The Kahayan runs through Palangka Raya on its way south to Bahaur, on the Java Sea. This web of waterways was once the transport route for communication, trade, and culture, but it is now mostly used by barges carrying raw materials for export. People journey along the much faster roads.
There are some remarkable ossuaries or Dayak bonehouses (sandung) alongside the road on the way to Tumbang Malahoi which are worth a closer look. This one is owned by a Dayak family, who have repainted and extended it, still living with the old traditions, and happy to chat with visitors.
