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.

Gunung Mulu National Park was inscribed as a UNESCO World Heritage Site in 2000. This picturesque natural wonder covers 52,865 hectares of primary rainforest that is dissected by several fast-flowing rivers and clear jungle streams. The oldest of Mulu's caves started to form about five million years ago. Heavy rain and continual erosion over the years have carved out the vast subterranean system that exists today. With its deeply-incised canyons, wild rivers, rainforest-covered mountains, spectacular limestone pinnacles, cave passages and features, Mulu has many outstanding scenic qualities.

The trek is organizes by travel operators and combines upriver travel, jungle trekking and an overnight stay at an Iban longhouse. The trail itself follows the route taken by Kayan headhunting parties who paddled up the Melinau River to Melinau Gorge. They then dragged their longboats through the forest for 3 km until they reached the banks of the Terikan River, where they launched headhunting raids against the people of the Limbang area.

Trekking to the Mulu Pinnacles is an adventurous journey deep into the heart of Gunung Mulu National Park in Malaysian Borneo. The trail winds through dense rainforest, limestone caves, and steep, rugged terrain, culminating in a challenging vertical climb to the viewpoint. At the summit, trekkers are rewarded with a breathtaking view of the sharp, jagged limestone formations that pierce through the jungle canopy — a surreal and unforgettable sight. It's a physically demanding but incredibly rewarding experience for nature lovers and thrill-seekers alike.
