Gunung Mulu National Park is a protected rainforest in Malaysian Borneo. It’s known for its dramatic peaks and caves, including the huge, bat-filled Deer Cave. The cave leads to the Garden of Eden, a hidden valley and waterfall enclosed by limestone cliffs. The Pinnacles at Gunung Api are tall, jagged limestone formations with steep trails and rare orchids. The summit of Gunung Mulu Mountain has views over the park.
