An active volcano rising about three thousand seven hundred and twenty-six metres, the second-highest volcano in Indonesia and the highest peak in West Nusa Tenggara, dominating north Lombok. Beside it a vast caldera holds the blue Segara Anak lake at about two thousand metres, whose name means child of the sea for its blueness, with a young volcanic cone at its centre and hot springs around it. Climbing Rinjani is one of Southeast Asia's best-known and toughest treks: two to four days with a guide and porters, camping in tents, starting from Senaru or Sembalun villages, up to the caldera rim overlooking the lake, and on to the summit before dawn for those who choose. Those who do not climb can enjoy the views from Sembalun and its valley farms. The national park fee for foreigners is about one hundred and fifty thousand rupiah per day, climbs are registered through the official online booking system, and a licensed guide and operator are compulsory, with full treks costing millions of rupiah depending on length. Climbing usually closes in the rainy season from January to March and when the volcano is active. Do not underestimate the climb: the paths are steep and sandy, the nights bitterly cold, and accidents have happened. Choose a known operator, bring warm clothes and give yourself a rest day after coming down.

The two-day crater-rim trek is possible for fit people with a guide and porters; the summit is very tough. If you are not used to mountain hiking, start with the Senaru waterfalls and the Sembalun farms.
