Register at the Rinjani Information Centre (RIC) in Sembalun Lawang (1,156m), meet your guide, and arrange National Park entry tickets. First, visit the nearby Volcanology Centre to check the seismograph, learn about the volcano, how the caldera and lake Segara Anak were formed, and its pattern of eruptions. Return to the RIC where the staff briefing describes the route details, local cultural traditions and what you might see, and explains rubbish management and safety procedures. The trek starts from Sembalun Lawang with a gentle ascent walking through open grassland used as cattle grazing by local people. Resting at Pos I Pemantauan (1,300), after about three hours from Sembalun we reach Pos 2 Tengengean (1,500m) enjoying the beautiful views of Mt. Rinjani’s summit (3,726m). After another hour ascent to Pos 3 Pada Balong (1,800m), we start the steep 3.5-hour climb amidst the pine-like Casuarina species locally known as Cemara, perhaps seeing evidence of wild pigs and the long-tailed grey macaque monkeys to the campsite at Plawangan 2 Sembalun crater rim (2,639m).
