Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at Senaru, the trailhead village: ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest in July and August; quietest from January to March.

Being there

On arrival

  • Paying — Cards work in hotels, malls and larger restaurants; carry cash for warungs, markets and small shops. QRIS codes are common, and bank apps from some Asian countries can scan them.
  • UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
  • Tipping — Not expected, though often hoped for in Bali and other tourist areas; if you tip, hand it over quietly.

Getting around Mount Rinjani

  • Apps — Rides: Bluebird, Gojek, Grab. Maps: Google Maps. Messages: WhatsApp. In parts of Bali, such as Canggu, Jimbaran and Uluwatu, local taxi drivers bar app pick-ups; walk a short way off before booking.

Within the park the only way to get around is to hike. Porters can be arranged to carry your supplies. More on Wikivoyage

  • Emergency — police 110 · ambulance 118 or 119 · fire 113. From a mobile, 112 is the general emergency number.
    TravelCharika is not an emergency service: we cannot call for help or send anyone. Numbers can change; if one fails, ask someone local or your hotel.
