Trekking Mount Rinjani in Lombok Island track is one of the best kept secrets Indonesia. Comparable with the more famous mountain tracks, Rinjani offers adventurous respect scenery, waterfalls, rain forest, wildlife, hot springs, caves, demanding hiking, pristine lake, interesting culture and of course the volcano.

Famous for its extraordinary beauty and eerie isolation, Mount Rinjani is the second highest mountain in Indonesia outside Irian Jaya. Although the dominant geographical phenomenon, its peak is rarely seen from the lowlands, as is often shrouded in clouds.


Mount Rinjani summit trek is one of the finest short adventures to be found anywhere in Asia and one of the region’s best kept secrets. Indonesia’s second highest volcano rewards intrepid hikers with an unforgettable experience and a backdrop that is truly awe-inspiring, almost otherworldly. Discover a summit with huge panoramas, an immense caldera partially filled by a 200 metre deep crater lake and Gunung Baru (new mountain) rising out of the depths in all its smoldering glory.

The huge volcano dominates the island of Lombok and is believed to be the abode of the local Gods. Every year Sasak and Balinese pilgrims climb up to the crater-lake known as Segara Anak (or child of the sea) to throw offerings into the holy waters and bathe away their ailments in the nearby hot springs.

The volcano and its caldera are protected by the Gunung Rinjani National Park which was established in 1997 and its forests and savannahs are home to a rich variety of flora and fauna. These include the rare ebony leaf monkey (or lutung) and the leopard cat (or bodok alas) as well as a wide variety of birds such as the sulphur crested cockatoo which is found no further west than Lombok (and the famous Wallace Line). Orchids are also a feature of the grassland areas and above the tree line we also find edelweiss (or bunga abadi).


The Rinjani summit trek is a serious undertaking and requires a good level of fitness and endurance although by designing the trek over four days we have shortened the daily distances and allowed for plenty of time to recuperate. In particular, the climb up to the summit (which begins in the dark to catch the stunning sunsets) is tough and in parts involves scrambling over loose scree.
