History of Mount Rinjani
The history of Mount Rinjani is one of the most extraordinary stories in the natural and cultural history of Indonesia. Standing 3,726 meters above sea level, Rinjani is not only Indonesia’s second-highest volcano but also one of its most sacred landscapes — where science, spirituality, and culture come together in perfect harmony.
From the catastrophic eruption of Mount Samalas in 1257 AD to the creation of Segara Anak Lake and the rise of Mount Barujari, Rinjani’s history is a powerful reminder of how destruction can give birth to beauty and renewal.
Over centuries, Rinjani has shaped not only Lombok’s geography, but also its people, traditions, and spirit.

1. Origins – The Ancient Samalas Volcano
Before Mount Rinjani existed, there was Mount Samalas, a massive stratovolcano dominating northern Lombok. Its fertile slopes supported early settlements in Sembalun, Senaru, and Bayan, providing life-giving rivers and forests.
Formed by the collision of the Indo-Australian and Eurasian plates, Samalas was part of the same volcanic arc as Bali and Java. For thousands of years, it stood as one of the largest volcanoes in the region — until a single event reshaped it forever.
2. The 1257 Samalas Eruption – When Fire Changed the World
In 1257 AD, Mount Samalas erupted with unimaginable force — one of the largest eruptions in recorded history. The blast sent ash into the stratosphere, circling the globe and cooling the Earth’s temperature for several years.
This eruption collapsed Samalas’ summit, creating a massive 8-kilometer-wide caldera. Over time, the crater filled with water, forming Segara Anak Lake, and a smaller cone — Mount Barujari — later rose from within it.
From this devastation, a new mountain emerged: Mount Rinjani, a symbol of rebirth and the enduring power of nature.
3. From Samalas to Rinjani – The Birth of a Sacred Mountain
The name “Rinjani” is believed to come from Dewi Anjani, the mountain’s divine guardian in Sasak and Balinese legend. For centuries, locals have viewed Rinjani as a sacred place — the center of balance between humans, nature, and the divine.
Streams flowing from its slopes feed Lombok’s rivers and farms, sustaining life across the island. To this day, Rinjani remains the source of Lombok’s water, livelihood, and spiritual identity.
4. The Legend of Dewi Anjani – Guardian of the Mountain
According to legend, Dewi Anjani was a princess from the ancient Selaparang Kingdom who withdrew into the mountain’s forest to meditate. She attained spiritual enlightenment and became the eternal guardian of Rinjani, blessing those who climb with pure intentions.
Every year, Hindu and Sasak Wetu Telu communities perform the Pekelem Ceremony at Segara Anak Lake — offering gold, silver, and prayers to maintain balance between humans and the unseen world.
This living tradition keeps the spirit of Dewi Anjani alive, reminding all visitors to respect Rinjani as both a natural wonder and a sacred home.
5. The 2018 Lombok Earthquake – Strength and Recovery
In 2018, a series of powerful earthquakes struck northern Lombok, temporarily closing Rinjani’s trekking routes.
The destruction was significant, but so was the response — local communities, trekking companies, and the Mount Rinjani National Park (TNGR) worked tirelessly to restore the trails.
Within a year, Rinjani reopened stronger and safer than before, a testament to Lombok’s resilience and unity.
6. Rinjani’s Scientific Significance
Today, Rinjani is one of Indonesia’s most closely studied volcanoes. Scientists have identified it as part of a complex volcanic system linked to the Flores Back-Arc Thrust Fault, explaining its frequent seismic and volcanic activity.
The Center for Volcanology and Geological Hazard Mitigation (PVMBG) continuously monitors Rinjani to ensure safe trekking conditions.
For travelers, every step on Rinjani is a journey through geology, ecology, and living history.
7. UNESCO Global Geopark & Biosphere Reserve
In 2018, Mount Rinjani was recognized by UNESCO as both a Global Geopark and a Biosphere Reserve, highlighting its unique geological, ecological, and cultural value.
This dual recognition celebrates Rinjani as a living model of harmony between people and nature. The national park’s management now involves collaboration between the government, scientists, and local communities — ensuring conservation and tourism develop sustainably together.
8. Ecology and Cultural Harmony
Rinjani’s 41,000-hectare landscape is home to rich biodiversity:
- 19 species of mammals
- 8 reptiles and 8 amphibians
- 160 bird species
- 25 butterflies and 447 tree species
- Over 150 medicinal plants
From the lowland forests to the savanna highlands, Rinjani’s ecosystems sustain agriculture, traditional medicine, and local culture.
It is both a natural classroom and a sanctuary — a reminder that Lombok’s strength lies in its connection to the land.
9. The Zero Waste Movement – Rinjani Go Zero Waste 2025
To preserve its pristine beauty, Rinjani National Park launched the “Rinjani Go Zero Waste 2025” program.
This initiative aims to make Rinjani the first plastic-free trekking destination in Indonesia.
All trekkers are encouraged to:
- Bring back all waste
- Use refillable bottles
- Support eco-conscious trekking companies
As a proud Lombok-based operator, Lombok Travel Agent fully supports this mission through responsible tourism, porter empowerment, and guest education.
