More than 20 villages encircle Mount Rinjani, offering various routes to ascend the mountain, including paths from Senaru, Sembalun, Torean, and Saja. The primary access points, however, are Senaru in the north and Sembalun Lawang in the east. The demanding three-day Rinjani Trek, which takes hikers from Senaru to the crater rim (Pelawangan), down to the breathtaking crater lake, and finally to Sembalun Lawang, is widely regarded as one of the best treks in Southeast Asia.
