The mighty Rinjani mountain of Gunung Rinjani is a massive volcano which towers over the island of Lombok. A climb to the top is one of the most exhilarating experiences you can have in Indonesia. At 3,726 meters tall, Gunung Rinjani is the second highest mountain in Indonesia. The climb to the top may not be easy but it’s worth it, and is widely regarded as one of the best views in the country.

Part of the famous ‘ring of fire’ this mountain also holds spiritual significance for the local people. It’s thought that the name Rinjani comes from an old Javanese term for ‘God’.

Around the slopes of Rinjani there are lush forests sprinkled with waterfalls and surrounded by stunning scenery.

Within the mountain is a crescent shaped lake, the breathtaking Segara Anak which is about 6km across at its widest point. This lake of sulfur is located 600 meters below the crater rim. Rising from the waters of this lake is a new volcano, Mt. Baru, which is a result of a series of eruptions during the 1990’s. Segara Anak is a spiritual place. The Balinese come here each year and perform a ceremony called pekelan where jewelry is placed in the lake as an offering to the mountain spirit.  The Wetu Telu people also regard the lake as holy and come here to pray on full moon nights.

Mt Rinjani lies within the Gunung Rinjani National Park. The park covers 41,330 hectares and sits inside a major bio-geographical transition zone (Wallacea). This is where the tropical flora and fauna of South East Asia meets that of Australasia. This National Park was established in 1997 and is one of over 40 throughout Indonesia.

For visitors, the three-day Rinjani trek route from Senaru to the crater rim, down to the Crater Lake then on to Sembalun Lawang, is considered one of the best treks in South East Asia. More adventurous trekkers may want to head all the way to the summit of the volcano.  This is best reached from Sembalun Lawang and takes four days, finishing up in Senaru.

To ensure that local communities benefit from tourism revenue, the Rinjani Trek is managed by a partnership of National Park officials, the public and private sectors of the Lombok tourism industry and community representatives. Community run cooperatives coordinate the Trek at the Rinjani Trek Center (RTC) in Senaru and the Rinjani Information Center (RIC) in Sembalun Lawang.

Revenue from tourism activities and entry fees is used for conservation, management and assisting the National Park with maintenance of the Rinjani Trek, thus ensuring its sustainability. This management model is unique in Indonesia and considered an example of best practice of ecotourism in Indonesia.


To Eat, To Buy, To Stay, To Do

There are cheap hotels around Sembalun and Senaru area with varied price and facilities. It's also possible to stay in private houses.


The climb is not to be taken lightly. You need good hiking boots. Once you arrive at the crater rim it tends to get cold and windy, so you will also need warm clothes.

A guide is essential as parts of the path are indistinct. Independent hiking is not recommended.

Don't go there during the rainy season since paths will be slippery. Often it is not possible to climb during rainy season due to the hazard of falling rocks.

It's better to bring your own sleeping bag but, if you don't have one, they can be hired.

Tents can be rented.
