Mount Rinjani has an elevation of 3,726 meters, which makes it the second-highest volcano in Indonesia. Its height places it among the most prominent peaks in Southeast Asia, and the mountain rises sharply from the surrounding lowlands, creating a dramatic difference between the coastal regions of Lombok and the alpine climate near the summit.
Because Rinjani is an active stratovolcano, its exact height has been measured several times by Indonesian geological agencies. The summit elevation has remained consistent in recent decades, even though the volcanic cone inside the crater, known as Mount Barujari, occasionally grows during small eruptions. Barujari is separate from the summit and does not affect the official height of the mountain itself. The summit point sits along the caldera rim on the eastern side of the crater and provides wide views of Segara Anak Lake, the surrounding ridges, and the neighboring islands.
The significant height of Mount Rinjani is one of the reasons it is such a popular destination for hikers. The climb to the summit is physically demanding because the trails gain thousands of meters of elevation in a relatively short distance. Weather conditions also change as trekkers move higher, with cooler temperatures and stronger winds near the peak compared to the warmer climate at the base in Senaru or Sembalun. This large elevation range contributes to the sense of adventure and makes Rinjani one of the most impressive volcanic mountains in Indonesia.
