Kayan Mentarang name is taken from the two names most important river in the park, the Kayan River to the south and north of the River Mentarang. Other sources mention that the name was taken from a plateau / plateau in the local mountains are named Apau Kayan vast stretches (Mentarang) of the Datadian / Long Kayan in the south through the middle and Apau Ping Long Bawan in the north. With a land area of about 1.35 million hectares, this forest expanse stretches across the northern part of East Kalimantan Province, precisely in the region Malinau, Bulungan Nunukan district and district, directly adjacent to the Sabah and Sarawak, Malaysia. Most of the areas included in Regency Malinau and some into the Nunukan district. Potential for tourism in National Parks Mentarang Kayan Hulu is Pujungan, Hulu and Hulu Krayan Kayan / Datadian.
TNKM area lies at an altitude between 200 meters to about ± 2500 m above sea level, covers the valleys of the lowlands, highlands, and the steep mountains that form clusters of various sedimentary and volcanic formations.
The high rate of forest destruction in the forests of Borneo and the number of switching functions, causing the TNKM a very special and should receive high priority in terms of biodiversity conservation and local culture that remains.
The main types of biodiversity are dipterocarp forests, Fagaceae-Myrtaceae forest or forest oak forest, the middle level and high mountains (above 1,000 m above sea level), the woods agathis, kerangas forest, swamp forest, a limited extent, as well as a special type " moss forest "at mountain peaks over 1,500 m above sea level. In addition, there are also various types of secondary forest. Forests in the woods along the river Bahau is hilly with steep cliffs are very difficult to climb from the river. Forests in this region has many waterfalls of various sizes, flow waterfall flow that is small enough to have a sloping riverbank and used by local communities to enter the forest in this region. Pujungan also known as the area where the sun never rises and never sank because it is often obscured by fog or clouds. However, sunlight through fog or cloud is able to make us blush burned skin without feeling the heat of the sun's heat as it is quite cold temperatures in this area. Can imagine the cold temperatures in the upstream Pujungan Apau Ping.
Instead of the usual stream originating from a spring at the headwaters of the mountains which then flows to the downstream branches up to the estuaries, rivers in the park came from Kayan Mentarang many springs in many mountainous regions upstream and flows into a large river heading downstream to the estuary. In the southern region of the park there is a river which empties after splitting Kayan district Selor and Tanjung Tanjung Palas, comes from springs in the upper teens and upstream Kayan Pujungan. Koala is a meeting of the intersection area between the rivers and streams Bahau Kayan is Bulungan district boundaries and Malinau. Kayan river in Tanjung Selor very quiet and began to flare as he entered the Long Lejau. Bahau river flows vary greatly from the peace that is not flowing to the turmoil rafting. Dayak community give the name of the river upstream Pujungan sei giram Bahau as a means of fast-flowing rocky river. And communities in this area is the driver-boatmen accomplished and compact. Bahau River at Long Aran region has the lowest water level and often cause the driver of the boat as well as local police work together to pull the boat ran aground in length can reach up to 20 meters was abuzz. Rocks in the river profile is also different, the two images on the left is the profile of the rocks found on the Kayan River area began to Simpang Tanjung Selor Koala, 2 images on the right is the profile of the rocks in the river Bahau encountered since the interchange area up to Koala Pujungan upstream.
Flora species that were reported in the region of which include at least 500 species of orchids and 25 species of rattan. There has also been successfully inventoried 277 species of birds including 11 species new to Borneo and Indonesia, 19 species of endemic and 12 endangered species. Some kind of interest include seven types of hornbills, Kuau King, Sepindan Kalimantan and other types of King Prawn. TNKM also a habitat for many protected species like the banteng (Bos javanicus), sun bear (Helarctos malayanus), pangolin (Manis javanica), clouded leopard (Neofelis nebulosa), porcupine (Hystrix brachyura), and sambar deer (Cervus unicolor). At certain seasons in the meadow at the headwaters of the Bahau, gathered a herd bull that emerged from the surrounding forest area and be an interesting sight to behold.
