History & Background

Mount Rinjani, with its majestically towering peak, boasts a rich geological and cultural history, making it more than just a typical trekking destination. Geologically, Rinjani is an active stratovolcano, part of the Pacific Ring of Fire. The mountain was formed through a series of volcanic eruptions over thousands of years. Its most significant modern volcanic activity was recorded in 1847, 1901, and the most devastating in 1994, which formed the caldera we know today. Within this caldera lies Segara Anak, a beautiful crater lake, and Gunung Baru Jari, an active cone volcano that continues to grow in the middle of the lake. The presence of this active volcano gives Rinjani a dynamic and unique geological characteristic.

Culturally, Mount Rinjani holds deep spiritual significance for the Sasak people, Balinese, and various other ethnic groups inhabiting Lombok Island. Rinjani is considered a sacred mountain, the dwelling place of gods and ancestors. Legends and myths surround this mountain, including the tale of Dewi Anjani, a princess of the Gowa Kingdom who is said to reside on Mount Rinjani and be the protector of the island. Religious rituals and traditional ceremonies are often held around the foothills of the mountain, especially by Hindu Balinese who have important temples on its slopes. Ceremonies like 'Banyu Pinaruh' and 'Piodalan' are examples of how local communities respect and interact with Rinjani.

The cultural diversity interacting with Rinjani creates a deep layer of meaning, making it a highly valuable natural and cultural heritage site.

Main Attractions

Mount Rinjani, standing tall at 3,726 meters above sea level, offers a series of stunning natural attractions and unforgettable experiences for every trekker. Its diverse landscape makes it one of Indonesia's most iconic mountains.

Rinjani Summit (3,726 m asl): This is the primary objective for most trekkers. The ascent to the summit is a challenge in itself, especially the final two hours, known as the 'hellish terrain' due to its steep incline and rocky, sandy ground. However, the view from the summit at sunrise is absolutely magnificent. You can see the vast expanse of Lombok Island, Sumbawa Island, Bali Island, and even distant mountains on the horizon. This moment is a precious reward for all your efforts.
Segara Anak Lake: Located within Rinjani's caldera, Segara Anak is a serene crater lake with beautiful turquoise-blue water. It spans approximately 1.1 million square meters and reaches a depth of 230 meters. In the center of the lake lies Gunung Baru Jari, an active cone volcano that continues to grow. The presence of a mountain within a lake creates a dramatic and unique landscape. Many trekkers choose to camp by the shores of Segara Anak to enjoy its tranquility and natural beauty, as well as perform spiritual rituals at the hot springs, which are believed to have healing properties.
Rinjani Crater: The Rinjani caldera itself is a geological marvel. Its massive size, the remnant of past devastating eruptions, provides a glimpse into the extraordinary power of nature. This crater is home to Segara Anak and Gunung Baru Jari.
Waterfalls (Sendang Gile & Tiu Kelep): Located at the foot of Mount Rinjani, near Senaru village, Sendang Gile and Tiu Kelep waterfalls are two stunning cascades. Sendang Gile, about 30 meters high, has a strong flow of water and a refreshing natural pool. Tiu Kelep, located a bit further from Sendang Gile, offers a more magical experience with water falling from a high cliff, often surrounded by mist. Both waterfalls are perfect spots to relax and rejuvenate after a trek.
Savanna and Tropical Forests: The Rinjani trekking routes traverse various types of vegetation. From dense tropical rainforests at lower altitudes, rich in biodiversity, to vast savanna plains at higher elevations. These forests are often shrouded in mist, adding to the mystical atmosphere. You might have the chance to see various endemic flora and fauna of Lombok.
Natural Hot Springs: Around Segara Anak Lake, there are several natural hot spring sources. Trekkers often use this opportunity to soak their bodies and relax tired muscles, while experiencing the unique sensation of bathing in the open air with beautiful scenery.
Senaru & Sembalun Villages: These villages are the most popular starting points for treks. Senaru offers access to waterfalls and the northern trekking route, while Sembalun is known for its beautiful green hills, often called 'Savanna Hills' or 'Nanggi Hills'. Both provide an initial glimpse of North Lombok's beauty before embarking on the trek.
