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 (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 Lawang, is considered one of the best treks in South East Asia. Those heading for the summit usually prefer to start in Sembalun Lawang.
RINJANI TREK INFORMATION
The Rinjani trek is a challenging mountain walk and you must be prepared with good equipment, warm and windproof clothing. Rinjani can attract severe storms, lightening and strong winds. When the weather is settled, the sun is intense and the nights frosty. Parts of the trail are steep and slippery. Beware of bad weather and risks of exposure to the wet and cold (hypothermia). If caught in an electrical storm, take shelter and avoid prominent ridges. Beware of stinging insects and plants. Leeches can be a nuisance in the wet season
Although Mt.Rinjani has not erupted in recorded history, Mt.Baru (2,351m) in the crater lake is an active volcano. It last erupted dramatically in 1994. Check the notice boards for recent hazards, and take advice from park staff and guides.Spring Water:
Fresh water springs are a feature of the trek and determine campsites. Your guide know where these are. During the drier months (July – September) some springs completely disappear. Park staff and guides constantly monitor these water sources to determine their abundance.
