Mulu

The Mulu National Park is a home to the world’s most ancient caves and rainforest. A recognized world treasure and recently listed as a World Heritage Site, this famous national park has been featured in countless articles and documentaries for its wide range of rainforests, biodiversity, massive limestone caves and inspiring beauty.

The caves and animals are the highlight of any visit to Mulu. Visitors hike and take boat rides to the entrances of these massive caves and explore the history of the earth on well maintained paths. Four caves have been set up for visitors; the Lang, Deer, Wind and Clearwater. Each cave is uniquely distinctive and is well set up for both visitor comfort and conservation. Each cave has lights and plank-walks to make it accessible to people of all levels of fitness.

The bat exodus from the entrance of the Deer cave at dusk, around 3 to 5 millions is a phenomenon definitely not to be missed!

World Heritage Site – This is Mulu.

A World heritage Area is an area that has been assessed by an international committee to have outstanding universal natural and/or cultural values; they are condidered to be the most priceless and irreplaceable locations on earth because of their natural beauty, importance in human history and culture, or their scientific value.

The History

Many, many millions of years ago, new mountains pushed high above the earths’ surface were rapidly eroded by heavy rains. Eroding rock produced grains of quartzite sand, carried by rivers from the mountains into the sea. Here it settled over time to form layers of sandstone. Again, the earth moved and its surface buckled and lifted, and so, the island Borneo was created.

In an ancient sea teeming with sea life, coral reefs developed to form lagoons between the reefs and this new island. Some 40 million years ago, these lagoons began to fill with layer upon layer of minute sea shells, compressed over the next 20 millions of years to become layers of limestone up to 1500 meters thick.

When the movement of the Australian and Asian landmasses caused the earths’ surface to buckle and fold about 5 million years ago, the land lifted once more. Tilting and cracking, the layers of limestone and sandstone were pushed up to create the mountains of Mulu. Some of Sandstone, some of limestone.

The relentless process of weathering by the elements of rain and time now began to shape the landscape we see today.

Although limestone forms in sea water, it has two very special features- it is porous, and it dissolves in fresh water.

As the rain falls on the limestone mountains, it passes through the soil and into the limestone itself through very small pores and small cracks. Seeping and trickling through the limestone, the water gradually dissolves the rock, making these pores and cracks larger and larger to create a remarkable series of cave chambers and passages.

And here at Mulu you will find.
