Mount Rinjani National Park

Indonesia's second-highest volcano, climbed over several days to a turquoise crater lake and a sunrise summit

Difficulty: Expert
Duration: 2-4 days for the summit and Segara Anak crater lake circuit
Summit elevation: 3726 m

At 3,726 metres, Rinjani is Indonesia's second-highest volcano and one of Southeast Asia's classic multi-day treks. Routes from Sembalun or Senaru climb through savannah grassland and forest to the crater rim, descend to the turquoise Segara Anak lake and its hot springs, and push for the summit before dawn over loose volcanic scree.

Getting there

Fly into Lombok International Airport near Praya, then transfer by road (about 2.5 to 3 hours) to the Sembalun or Senaru trailhead villages, where registered trekking operators are based.

Sturdy trekking boots with ankle support
