Mount Rinjani Trek

Mount Rinjani Trek is a multi-day hike on Lombok, Indonesia, built around the volcano’s summit at 3,726 m and the Segara Anak crater lake area. The route is commonly organized as a 3-day/2-night itinerary that reaches the main high point and then continues through the crater and hot-spring zone.

This trek is considered strenuous and aims at high elevation work on steep, loose volcanic ground. Day-by-day timing typically includes an early wake-up for the summit push (night-to-dawn start) and a long, downhill finish back toward the northern trailheads.

The most popular classic access patterns start from either Sembalun or Senaru, with Sembalun generally associated with a longer, more open ascent and Senaru associated with rainforest terrain on the descent. Both versions are used to connect the summit segment with the crater rim and onward toward Segara Anak and the hot springs.

Your planning should account for park access logistics: trekking inside Mount Rinjani National Park requires a guide and permits, which are typically bundled in organized packages.

Seasonality matters. The dry season is commonly treated as May–October, with July and August being the busiest months for bookings and trail traffic.

Because it’s an active volcanic landscape and the route runs at altitude, expect major day-to-day physical demands rather than an easy endurance stroll; the trekking difficulty is aimed at fit, experienced hikers who can handle steep ascents/descents over multiple days.
