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 three administrative district of West, East and Central Lombok. The park ecosystem is in the transitional zone between Asia and Australia (Walaceae 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 (Anaphalis viscida), tiger orchid (Vanda sp.), alang-alang grass (Imperata cylindrica), cemara trees (Casuarina trifolia and Casuarina ocidentale).
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 Lawang, is considered one of the best treks in South East Asia. Those heading for the summit usually prefer to start in Sembalun Lawang.
The village of Senaru is the main gateway to Gunung Rinjani National Park, the most popular start point for the three day Rinjani Trek 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.
A model for ecotourism in Indonesia, the community-based activities are focussed on the Rinjani Trek Centre in Senaru, the most popular starting point for the tough trek. 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.
