KILIM KARST GEOFOREST PARK
The Kilim Karst Geoforest Park is formed from 7 reserved forests inclusive of the mangrove forest. The rocks in this geoforest park are formed from the limestones aged 350 – 490 million years old. Karst is the uneven shape of the earth’s surface that is formed from the limestone. The sharp peak on the many rocks here are formed in affect of the acidic rainwater that fell on the limestone causing the dissolvent on the fracture and the layers of rocks leaving the sharp peaks on the rocks here. There are several geosites that are high in value and would be interesting to explore. Among them are the Gua Kelawar, Gua Langsir, Pulau Anak Tikus, Teluk Cina Mati, Tasik Langgun, Teluk Mempelam, Gua Cherita, Gua Dedap and Tanjung Rhu.
- Kilim Karst consists of Setul Formation (dark grey coloured limestones) which are formed from limestones.
- It is formed from 7 different reserved forests which are the Hutan Simpan Pulau Langgun, Hutan Simpan Kuala Kisap, Hutan Simpan Tanjung Dagu, Hutan Simpan Gua Cherita, Hutan Simpan Ayer Hangat, Hutan Simpan Selat Panchur and Hutan Simpan Pulau Timun.
- The word ‘Karst’ carries the meaning of the shape morphology or the uneven landscape, which is normal for limestones, like caves and sea stacks.
- The Geosites in this area are:
Sungai Kilim Geosite Pulau Langgun Tanjung Rhu Geosite
Gua kelawar, Gua Langsir, Gua Buaya
Pulau Tanjung Dendang Geosite (Pulau Anak Tikus,Teluk China Mati,Tasik Langgun, Teluk Mempelam)
Gua Cherita,Gua Dedap, Tanjung Rhu
- Surrounded by Mangrove Swamp Forest with the dominant mangrove species like bakau kurap (Rhizophora mucronata) and bakau minyak (Rhisophora apiculate).
- There are 3 different species of insects-eating bats from the Bat Cave which are the kelawar ladam bulat terbesar (Hipposideros armiger), kelawar ladam bulat besar (Hipposideros larvatus) and kelawar jari panjang (Miniopterus medius).
- Pulau Anak Tikus is a special location where fossils (carcass or traces of animals, plants and other life forms that has been preserved since the stone age) can be found in this area, for example; gastropod fossils and brachiopods fossils. This area is also known as a habitat for eagles. There are 2 types of eagles that can be found here which are; helang merah – red eagle (Haliastur indus) and helang laut – sea eagle (Haliaeetus leucogaster).
- Setul Formation aged 370 – 490 million years old.
- The built up area is 8,261 hectares
- The bogak tree (Cycas clivicola) has been in existance since 200 million years ago.

This cave obtained its name from the hundreds of bats that has been living inside the cave. There are 3 different species of insects-eating bats from the Bat Cave, which are the Kelawar Ladam Bulat Terbesar (Hipposideros armiger),Kelawar Ladam Bulat Besar (Hipposideros larvatus) and Kelawar Jari Panjang (Miniopterus medius). Shells/oysters can be seen stuck on the walls of the cave in which the age of it has been determined to be of 500 years old. The shells were used as a marker for the ancient sea levels. The position of the shells has proven that the sea level used to be 2 meters higher than the current level.
Gua Langsir has obtained its name from the stalactite that is shaped as a curtain on this cave. This cave is the entrance to a salt-water lake. The existence of this cave influenced the tide levels of the lake. A platform has been built facing the middle of the lake for the better appreciation at a 360 degrees level on the amazing flora and fauna that can be seen around the cave.
Pinnacles are the sharp edges of the rocks that have undergone the process of dissolution due to the rainfall. This pinnacle is also known as fiery peak.
Anak Tikus Island is an island formed due to the continuous erosion at the end of the cape of Pulau Langgun. Consequentially this cape broke off and became a small island. This small island is abundant in fossils of shell type that has come into existence around 480 million years ago in a marine environment. The fossils that can be found here are shaped similar to seashells and oysters, which are known as gastropod (ancient shell) and brakiopod (ancient oysters) as well as sefalopod (ancient squid).
Teluk Mempelam is located in Pulau Langgun and an example of a location of Setul Formation. The cluster of rocks on this beach contains several of fossils, including trilobite, conodont (teeth), crinoids (sea-lilies) and gastropod. The continuous erosion on the beach has left several sea stacks and staged erosion of ancient waves. To those interested in camping at this bay, the camping site here is near to the source of water and equipped with basic facilities.
This cave has two chambers on two different levels. The lower chamber is a raised sea cave. From the higher chamber can be seen a spectacular scenery of the vast emerald green sea at the bay. There are several peculiar stalagmite formations that can be found on some of the chambers. There are trails of stains and substances left by the swift bird (burung walit) and the bats on the walls and ceiling that once had inhabited the cave. This cave have been known to have a myth on a forbidden love story between the Princess of China and the Prince of Rome where the Garuda bird has kidnapped the princess and hidden her in this cave. Unfortunately, the paintings have slowly disappeared due to the weather and time.
This cave is a tunnel that connects the sea and the Dolina Lake. A small boat can pass through this cave when the tide is low. This cave is formed due to the erosion activity by the waves from thousands of years ago. Through this cave we can witness the stunning view of the bay and the surrounding islands.
