2. Where is Mount Rinjani and How Do You Get There?
Mount Rinjani lies in Lombok, West Nusa Tenggara, Indonesia, east of Bali. It is the centerpiece of Mount Rinjani National Park, a protected area covering 41,000 hectares.
Getting to Lombok
- By air: Fly into Lombok International Airport (Praya). Direct flights connect from Bali, Jakarta, Surabaya, and Singapore.

Starting Points for the Hike
- Senaru (north): Gateway for crater rim treks and longer expeditions.

Most trekkers spend a night in Senaru or Sembalun villages before starting.
