4 Days Mulu Caves & Pinnacles Adventure

Deep in the virgin tropical forests of Sarawak, along an unbroken 40km band of limestone peaks, lie one of earth’s natural wonders – The Giant Caves of Mulu, a world’s heritage site.  Gazetted in 1974 as the largest Park in Sarawak, Mulu National Park were designated as Malaysia’s first World Heritage Sites in 2000.  At 4 degree north, it has plenty of rainfall (from 4.5m to 1600m per year) and sunshine (19 – 34 C).  Its biodiversity includes 1,500 species of flowering plants, 1,700 mosses and liverworts, 450 ferns, 4,000 fungi, 80 species of mammals, 50 fish, 270 birds, 50 reptiles, 75 amphibians and an estimated 20,000 species of insects. (Extract from Mulu World Heritage Area).Mulu began millions of years ago under the sea where layers of sandstone, limestone and shale were formed and then lifted above the sea level, buckled and folded to form steep mountains of sandstone and limestone. Over time with heavy rain, river, changing level of underground water table and chemical reaction of mildly acidic water eroded them to form some of the most dramatic karst landscapes of pinnacles, caves, cracks, sink holes, joints, pendants, blades, passages, chambers while evaporation created stalactites, stalagmites and columns.
