Packing list

Mountain hiking packing checklist

A general list for hiking tropical mountains in Indonesia

On Indonesia's high summits the temperature can drop close to or below freezing before dawn, especially when it is windy and wet. Use this list as a reminder, then adjust it to the forecast on your mountain's page and the trail manager's rules.

Clothing (layering system)

  • A quick-drying base layer (avoid cotton for hiking)
  • An insulating layer: fleece or a synthetic insulated jacket
  • Waterproof jacket and trousers (rain often falls from midday to afternoon)
  • Beanie, gloves, buff/neck gaiter
  • Spare socks and dry sleeping clothes, kept in a waterproof bag
  • Hiking shoes or sandals with lugged soles

Sleeping and camping

  • A tent you have practised pitching before the trip
  • A sleeping bag rated for the lowest forecast temperature at the summit/camp
  • A sleeping mat (important to block cold from the ground)

Navigation and safety

  • Offline trail map and a fully charged phone, plus a power bank
  • Headlamp and spare batteries, especially for a pre-dawn summit attack
  • Whistle and emergency blanket
  • Personal first-aid kit and regular medication
  • A turnaround time agreed by the group
  • Basecamp/manager contact number and hiking registration info (SIMAKSI where required)

Water, food and rubbish

  • Enough drinking water, and information from the manager about water sources on the trail
  • Energy food that is easy to eat while walking
  • Stove and fuel that comply with the area's rules
  • Rubbish bags: carry all your rubbish down

Reading the forecast before you go

  • Low feels-like temperature (≤ 0 °C) → bring extra insulating layers, gloves and a beanie.
  • Rain ≥ 5 mm → rain jacket and trousers are a must; protect electronics and sleeping clothes.
  • Thunderstorm signal → avoid ridges and exposed summits, consider postponing.
  • Wind ≥ 30 km/h → choose a sheltered tent spot, watch out for hypothermia.
