Located in Miri, Sarawak, this national park and UNESCO world heritage site is a must-see destination when you visit the Borneo region. Come here to see the cave formations of Sarawak Chamber and Clearwater Cave. But just know that it is required to be accompanied by a licensed guide to enter the park’s caves. Besides the caves, popular activities here include the canopy, hiking trails, and boat rides. There are homestays within two kilometers of the park at Mulu. Mulu even has a Marriott Resort & Spa, and across the river is a lodge and inn at Benarat.
