The History and Significance of Gunung Rinjani

Gunung Rinjani's eruptions date back 50,000 years, shaping Lombok's fertile soils that sustain rice terraces visible from trails(National Geographic). In the 19th century, a major blast in 1846 altered the crater lake's chemistry, creating mineral-rich hot springs used today. The Sasak Lombok people revere it as a spiritual site, hosting annual pilgrimages during full moons.

Designated a national park in 1997, it protects endemic species like the Rinjani scorpion(IUCN). UNESCO recognizes its biodiversity as a tentative World Heritage site. Historical trails trace ancient trade routes across the island.
