The tour begins with an early morning departure from Senaru by 4WD vehicle to Sembalun, where we register at the Rinjani Trek Centre (1,156 m) before starting our trek. The trail winds through undulating open grasslands, and we take breaks at Pos 1 and Pos 2 for rest and snacks. At Pos 3 (1,800 m), we stop for a longer lunch break before continuing our steep climb up the crater rim. We camp for the night at Sembalun Crater Rim (2,639 m), with stunning views of the sunset, Lake Segara Anak, and the summit of Mount Rinjani.
