Gunung Rinjani is the second highest mountain in Indonesia (excluding Irian Jaya). It's an active volcano (last eruption 1994) which dominates the landscape of Lombok island. The highest point is situated on the eastern edge of a huge crater (8 km across) with large (6 km across) and very beautiful crater lake, named Segara Anak. There are two normal routes to the top. The eastern route starts in Sembalun Lawang village (1180 m). It's almost impossible to follow the trail on your own in the lower parts; a guide is essential. Staff at the Wisma Cemara Siu Losmen (boarding house) will help you arranging a guide and porters. First you walk up and down for about 15 km to reach the slopes of the mountain. Then you climb another 4h very steep through sparse forrest to the crater rim (2650 m). The next day you should start at 3am to reach the summit at sunrise and to return to the campsite before the clouds come in. You can return to Sembalun Lawang the same day. Better option is to descend to the crater lake (2003 m) and stay one night at the hot springs near the lake. The third day you climb up to the rim on the northern side (2634 m) and then walk down to Senaru village (860 m). You need good shoes, warm clothing and lots of water.
