Anyone visiting Lombok island, Indonesia, will notice a looming mountain dominating the island’s landscape. Lombok island is only slightly smaller than Bali, yet almost half of its land area is occupied by Mount Rinjani (Gunung Rinjani). The volcano is 3,726 m in height.

It is the second-highest volcano in Indonesia, after Mount Kerinci in Sumatra. The Segara Anak Lake situated at one of Mount Rinjani’s ancient craters. It is famous for its ocean blue water that contributed to its name- Child of The Sea. Mount Rinjani’s constant volcanic activity also forms several hot springs around the lake.

These natural pools are popular not only among trekkers. But also among locals, since they believe in the hot springs’ healing properties. As for flora and fauna, Mount Rinjani hosts unique biodiversity since it’s located in a transitional Wallacea region.
