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.
Within the mountain is a crescent shaped lake, the breathtaking Segara Anak which is a spiritual place. The Balinese come here each year and perform a ceremony to the mountain spirit. The Wetu Telu people also regard the lake as Holy and come here to pray on full moon nights. 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.
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.
Three-day Rinjani 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.
The park covers an area of 41,330 ha on the northern part of Lombok. Named after Indonesia’s second highest volcanic peak outside of West Papua, the peak of Gunung Rinjani (3,726m) dominates the landscape. Within the crater is the spectacular Segara Anak lake and the still-active volcano Gunung Baru (2,363m). It is surrounded by a further 66,000 ha of Protection Forest and covers the four administrative district of West, East, north and Central Lombok. The park ecosystem is in the transitional zone between Asia and Australia (Wallace zone). Average rainfall is about 3,000 mm annually. Gunung Rinjani is rich in a variety of flora, fauna and vegetation types. On the south western side of the mountain is the most eastern extent of primary rainforest in Nusa Tenggara. This gives way to monsoon forest and drier climate in the east, and savannah in the north east. Notable flora includes the everlasting edelweiss flower (Anopheles viscid), tiger orchid (Vanda sp.), alang-alang grass (Imperata cylindrical), cemara trees (Casuarinas trifoliate and Casuarinas occidental).
Mt. Rinjani, one of the over 40 National Parks throughout Indonesia, was established in 1997. It is valued and protected for its spiritual as well as natural values, and is worshipped by thousands of Balinese as well as Sasak pilgrims. Hot springs near the crater lake are sought after for their healing powers. Over 20 villages surround Rinjani and there are many routes up the mountain, but the main access is from Senaru in the north and Sembalun Lawang to the east. The challenging three-day Rinjani Trek route from Senaru to the crater rim (Plawangan), down to the stunning crater lake then on to Sembalun, is considered one of the best treks in South East Asia. Those heading for the summit usually prefer to start in Sembalun.
The village of Senaru and Sembalun is the main gateway to Gunung Rinjani National Park, the most popular start point for the three day Rinjani Trekking up Indonesia’s second highest volcanic peak (3,726m). For the people of Lombok, Sasak and Balinese alike, the volcano is revered as a sacred place and the abode of gods. Within the spectacular crater, the Segara Anak Lake is the destination of many pilgrims who place offerings in the water and bathe away disease in the nearby hot springs. Developed with New Zealand Government assistance since 1999, the Rinjani Trek Centre embodies under one roof (satu atap) the unique partnership of the National Park, tourism industry and local communities that has been forged to manage and protect the Rinjani mountain environment.
