Niah Caves is a complex of caves located in the Miri Division of Sarawak, Malaysia. The caves are one of the most important archaeological sites in Southeast Asia, containing evidence of human habitation dating back over 40,000 years.

The caves are made up of a series of limestone caverns and chambers, with the largest chamber measuring approximately 75 meters (246 feet) wide and 30 meters (98 feet) high. The caves contain an abundance of stalactites, stalagmites, and other formations, making them a popular destination for tourists and spelunkers.

In addition to their natural beauty, the Niah Caves are renowned for their archaeological significance. Excavations have uncovered evidence of human habitation dating back to the Paleolithic era, including tools, pottery, and the remains of human skeletons.

One of the most notable discoveries in the Niah Caves is the skull of a Homo sapiens dating back approximately 40,000 years, making it one of the oldest human remains found in Southeast Asia. Other significant finds include cave paintings depicting human figures and animals, as well as evidence of trade and commerce between ancient civilizations.

Today, visitors to the Niah Caves can explore the caverns and view some of the artifacts on display in the nearby museum. Guided tours are available, and visitors are advised to wear sturdy shoes and bring a flashlight, as some parts of the caves are quite dark and slippery.
