Limestone Pinnacles

Gunung Mulu National Park’s most remarkable features are the world’s finest example of karst collapse and the 50-meter tall, razor-sharp, limestone Pinnacles on the northern end of Gunung Api. The Pinnacle trail is dangerous and very steep – it stretches for a distance of 2.4km and reaches an altitude of 1,200m above sea level, requiring a certain level of fitness to complete it. The Pinnacles Summit Trek, for example, will usually require a 3-day, 2-night trek.
