When volcanic and seismic activity permits, 12,224-foot (3,726-meter) Mt. Rinjani is one of Indonesia’s great volcano climbs—even if you stop, as many climbers do, at the crater rim. The towering peak, complete with crater lake, dominates north Lombok, so even when the mountain is closed to visitors, hikes on the lower slopes appeal.
Climbing Mt. Rinjani is a serious hike that involves at least one night camping on the mountain. Any organized trek should include guides, porters, tents, food, water, and sleeping bags, and prices will vary according to the trek length and other extras. It’s possible to arrange Rinjani hikes on the spot in Senaru or Sembalun Lawang, but many travelers prefer to book ahead online.
When the mountain is closed, the crater and summit are inaccessible. Scenic waterfall hikes out of Senaru may provide some consolation.
Things to Know Before You Go
- Mt. Rinjani sometimes closes, as in 2018, because of volcanic and/or earthquake activity, and it regularly closes due to rain.
- Temperatures at the summit can drop to close to freezing. Wear hiking boots and bring a warm jacket, gloves, and a hat.
- Mt. Rinjani is the second-highest volcano in Indonesia and attracts as many as 100,000 trekkers in a year.
How to Get There
The hillside village of Senaru is the most popular base both for climbing Mt. Rinjani and for exploring its scenic lower slopes. Despite its status as a trekking center, there is no public transport. Many travelers prefer the convenience of a tour that includes transport from Lombok port or airport.
When to Get There
Mt. Rinjani is regularly closed to visitors during the worst of the rainy season (roughly from December until late March) and occasionally closed because of geological activity. Climbing can be at its most colorful on full moon nights, when local Sasaks make pilgrimages—the mountain is sacred both to them and Balinese Hindus.
Mt. Rinjani Climbing Routes
Most Mt. Rinjani climbs start from Senaru or Sembalun Lawang and involve at least one night camping on the mountain. The shortest route to the summit is a 2-day hike from Sembalun Lawang; the shortest trek takes you from Senaru to the crater rim in two days. It’s possible to spend up to four days and three nights exploring, but most opt for a 3-day, 2-night trek that includes the crater lake.
