Mount Rinjani Trek emergency & health guide: hospitals, rescue, 112 and park rules

Emergency numbers

Phone signal on Rinjani is patchy and often absent in the crater, so stay with your guide and do not count on your phone. Under the 2025 park rules the guide gives first aid, informs the organiser and the park, and the casualty walks down assisted or is carried by stretcher to the trailhead; helicopters fly only in clear weather. Make sure your insurance covers trekking to 3,726 m and helicopter evacuation, tell someone at home your dates, and check the weather and the volcano alert level before you start.

Rules to know

• Annual closure: all routes are closed from 1 January to 31 March for the rainy season. In 2026 tickets went on sale on 6 March and the trails reopened on 1 April. Routes can also close at short notice for fire, eruptions or bad weather.
• Booking: every trekker needs a ticket in the official eRinjani app for a fixed route and dates, and must check in and check out at the gate. Quotas are limited. If you do not check out, your account can be blacklisted.
• Foreign trekkers must book through a licensed trekking organiser with a certified guide. From January 2026 one guide may lead at most 4 trekkers, and one porter serves at most 2 foreign or 3 Indonesian trekkers.
• Health and safety: you need a health certificate issued the day before the climb, a signed consent statement and the safety briefing. You get an RFID wristband at the gate. Under-17s need a guide or an experienced adult and written parental permission.
• Insurance: the 2025 rules require insurance that covers evacuation. Carry your own travel insurance for trekking to 3,726 m with helicopter rescue, and ask your organiser what the ticket includes.
• Fees from 3 November 2025: Rp 250,000 per foreign visitor on the Sembalun, Senaru and Torean routes (Rp 200,000 on Timbanuh, Aik Berik and Tetebatu). Packages from licensed organisers normally include the fee.
• Zero waste: carry out everything you bring in. Organisers check it, and breaking the rules can lead to sanctions for the organiser and a blacklist for trekkers.
• Fire: careless use of fire is banned and bags are checked for fire sources. In September 2026 a fire near Torean burned about 1,100 ha and closed the Senaru route until 3 October.
• Drones need a special permit with a Rp 2 million fee; drones flown without one are confiscated. Speakers and guitars are banned on the trail.
• Summit trail: start with your guide at about 2–3 am, keep to the marked path on the narrow scree ridge, and turn back in fog or strong wind. In June 2025 a hiker died after a fall at Cemara Nunggal, about 2,800 m up.
• Camp only at the official camps (Pelawangan Sembalun, Segara Anak, Pelawangan Senaru) on your booked dates, and do not use soap or shampoo in the lake or the hot springs.

Clinics and health centres

There is no clinic on the mountain. Nusa Medica Clinic in Sembalun Lawang has a 24-hour emergency service and issues the health certificate you need the day before the climb; the community health centre (Puskesmas) below Senaru gives basic care. The nearest hospitals with a 24-hour emergency department are RSUD KLU in Tanjung (Senaru side) and RSUD dr. R. Soedjono in Selong (Sembalun side); the main referral hospitals are in Mataram.

There is no pharmacy on the trek, and the mountain villages have little choice. Buy your medicines, blister plasters, rehydration salts and any altitude medication in Mataram before you go. There is no electricity at the camps: carry a power bank.
