The Lambir Hills National Park is located along the Miri-Bintulu Road, some 30km south of Miri City, it's a short 30 minutes drive from town.
The park was gazetted and published to public on 15 May 1975. It covers an area of about 6,952 hectares which consists of the central portion of the Lambir Hills, a rugged east-west trending sandstone escarpment with a maximum height of 465 metres.
This park has an outstanding regional and global conservation significance for its extraordinary species-rich forest, ideal for botanist and researchers throughout the world. Moreover, the park has a high potential value for recreational, educational and research purposes.
More than half of the area of the park is covered with rich natural Mixed Dipterocarp Forest where huge, tall dipterocarp trees such as kapur, meranti, kempas and selangan batu are found. Other forest types found are Kerangas Forest with snaller and shorter trees like rhu bukit and selunsur bukit, low shrubs, picther plants and orchids; secondary forests and logged-over forests.
Apart from the various tree species, the park is very rich in order plant species such as ferns, gingers, vines, palms, mushrooms, moss and lichen, flowering and fruiting shrub trees, climbers and creepers. There are a good variety of animals including bats, monkeys, pangolins and barking deer. Up to 157 species of birds have been recorded.
There are a series of small waterfalls along the Sg. Liam, about half a kilometre from the Park Office following the waterfall are called First, second and Third or Latak. An oil well is located very close to the Second Waterfall. Other accessible falls are the Pantu and Nibong Waterfall along the pantu Trail and the Pancur, Tengkorong and Dinding Waterfall along the Bakam Trail.
The latak Waterfall is popular with visitors. it is about 25 metres high and pluges sheer into a large deep pool with a broad sandy poolside. It is a very pleasant spot for swimming, sunbathing and picnicking.
A 22 metre Tree Tower is situated on the Pantu Trail, about a kilometre from the Park Office. Visitors can climb and view the scenic Dipterocarp forest profile. it is also an excellent place for bird watching. 237 species of birds have been recorded in Lambir.
The trail system is composed of primary, secondary and tertiary trails (see map). The four primary trails, are Main, Pantu, Lepoh-Ridan and Bakam. The seven secondary trails are Latak, Nibong, Bukit Pantu, Pantu Waterfall, summit, Tengkorong and Pancur. Dinding Trail is the only tertiary trail in the Park.
These trails are constructed for visitors to explore the forests, hills, valleys and waterfalls. They are well-marked no guide is required and can be explored unguided. However, the Summit Trail which leads to the Lambir's Summit, does require a guide and is excellent for adventurous hikers.
A joint Long term Ecological Dynamic project between Center for Tropical Forest Science, Smithsonian; Ministry of Education, Science and Culture, Japan and the Forest Research Centre, Sarawak has a permanent 52 hectare research plot in Lambir. This project has established a 52 hectare forest plot with all trees over 1 cm diameter at breast height tagged. There are over 320,000 individuals and 1,200 species.
