Rinjani Trekking Via Senaru
This is by far the most used route as it allows the (relatively) less strenuous trek to the crater rim only. You start at an elevation of 600 m in Senaru village, normally in the late morning or early afternoon and make the 6 hour ascent to the crater rim before dark. First part of the trek is through tropical rainforest. Look and listen out for the lutung, or black monkey, swinging through the trees in the late morning. They are extremely shy, unlike for the common macaques which may gather near rest stops waiting for scraps. The route passes through POST II at 1,500 m.
