Mount Rinjani National Park centers on Mount Rinjani, an active stratovolcano on Lombok island whose summit reaches 3,726 metres. The park protects the volcano, its caldera and adjacent ecosystems.

Trekkers and climbers come for multi-day routes that ascend to the crater rim and the caldera lake Segara Anak, with typical itineraries of two to three days for the common routes from Senaru or Sembalun. The park also offers hot springs, waterfalls and diverse montane forest below the crater rim.

Rinjani is a volcanic edifice formed by repeated eruptions; it remains active and has a history of recorded eruptions. Local villages on the volcano’s flanks have long cultural connections to the mountain and the caldera lake.

The park occupies the northern sector of Lombok island in West Nusa Tenggara province of Indonesia; access is commonly from the villages of Senaru on the west flank or Sembalun on the east flank.

• Elevation: Mount Rinjani’s summit reaches 3,726 metres and is the dominant volcanic cone on Lombok island.
• Trek season and duration: Best climbed in the local dry season, typically May through September; standard treks take 2 to 3 days to reach the crater rim and camp at Segara Anak.

What to See#

• Segara Anak (crater lake): A large crater lake within the volcano’s summit caldera that is a primary overnight campsite on multi-day treks and a central natural feature of the park.
• Senaru and Sembalun trailheads: Senaru and Sembalun trailheads on the western and eastern flanks respectively provide the main trekking approaches and villages used for permits, guides and supplies.
• Crater rim camps: Pelawangan and the crater rim areas used as high camps and viewpoints for sunrise and crater views during multi-day ascents.

Mount Rinjani National Park is on Lombok Island. Travelers usually reach Lombok via flight or ferry from Bali (Padangbai to Lembar ferry) and then drive to Sembalun or Senaru villages, common trailheads for treks. Park permits and guides are arranged in Sembalun or Senaru; many visitors book multi-day treks with licensed local operators.

• Hire a licensed local trekking company for multi-day climbs - Rinjani's routes are steep and camping logistics matter.
• Book permits and a guide in advance during the high season (June-September).
• Visit early in the morning for Segara Anak lake views and to avoid afternoon storms on the crater rim.
