The peat forest surrounding the Kumai River suffered from droughts and fires in 1982–83 and again in 1997–98.[7] The Tanjung Puting park, about half of which is peat swamp forest, is famous for a population of about 4000 orangutans. It is accessed from Kumai by speedboat down the Kumai River and then up the Sekonyer River to Camp Leakey, a journey that takes about 1.5 hours.[8] The Kumai River forms the northern border of the Tanjung Puting park.
