Things to Do at Mount Rinjani

Mount Rinjani is Indonesia's second-highest volcano, and reaching either the crater rim or the summit is a genuine multi-day trek, not a single sunrise outing like Batur or Bromo — expect to camp overnight on the mountain, with a mandatory local guide and porter team required for the climb. The reward is Segara Anak, a crescent-shaped crater lake with its own smaller active cone rising from the water, along with hot springs on the crater's edge that are a welcome relief after a long day of climbing. Weather at altitude turns genuinely cold overnight, which is the single most common equipment mistake among visitors used to Bali's coastal heat, and conditions on the trail can close the route entirely during the wetter months. This is a serious trek for reasonably fit, prepared hikers, not a casual add-on to a beach holiday. Below are the top-rated Rinjani trekking tours and multi-day packages.
