Why Packing Right Matters on Rinjani

Mount Rinjani reaches 3,726 metres above sea level. Temperatures near the summit and crater rim can drop below freezing at night, even though you'll be trekking through tropical heat at lower elevations earlier the same day. The weather changes rapidly, trail conditions are rugged, and you'll be camping on an active volcano. Getting your kit right isn't just about comfort — it's about safety.

This packing list is designed for a standard 3-day/2-night trek. Adjust quantities for longer expeditions.

Footwear & Lower Body

  • Trekking boots — waterproof, ankle-supporting. This is the single most important piece of equipment. Do not attempt Rinjani in trail runners or sandals.
  • Sandals or camp shoes — lightweight flip-flops for use at camp and the hot springs.
  • Wool or synthetic trekking socks — bring at least 3 pairs. Avoid cotton.
  • Gaiters — extremely useful on the volcanic scree sections above the crater rim.
  • Trekking trousers — lightweight, quick-drying. Convertible zip-offs are practical.
  • Thermal base layer leggings — essential for cold nights and the early morning summit push.

Upper Body Layering System

The key to comfort on Rinjani is layering. You need to be able to strip down while climbing in midday heat, and fully insulate for cold nights at 2,600 m elevation.

  • Moisture-wicking base layer (long sleeve) — merino wool or synthetic, not cotton
  • Mid layer fleece or down jacket — critical for evenings and summit mornings
  • Waterproof/windproof shell jacket — protects against sudden rain and wind chill
  • 2–3 lightweight trekking shirts for the daytime approach sections

Sleeping & Shelter

  • Sleeping bag rated to at least 0°C — ideally -5°C for summit nights. This is non-negotiable.
  • Sleeping bag liner — adds warmth and keeps your bag clean
  • Note: Tents are typically provided by your trekking operator. Confirm this when booking.

Navigation & Lighting

  • Headlamp + spare batteries — the summit push begins around 2–3 AM. A good headlamp is essential.
  • Trekking poles — highly recommended for steep descents; can be rented in Senaru or Sembalun if you don't own a pair

Health, Hygiene & First Aid

  • Personal first aid kit: blister plasters, ibuprofen, rehydration salts, antihistamine, antiseptic wipes
  • Sunscreen (SPF 50+) and lip balm — UV exposure is intense at altitude
  • Insect repellent — important on lower forest trails
  • Biodegradable wet wipes for personal hygiene at camp
  • Small trowel and waste bags (pack out all waste)
  • Water purification tablets or a portable filter — always have a backup

Food, Water & Energy

  • 2–3 litre water capacity (bottles or hydration bladder). Refill at springs en route — treat all water before drinking.
  • High-energy trail snacks: nuts, dried fruit, energy bars, chocolate
  • Note: Meals are typically provided by operators and cooked by your camp crew.

Documents & Extras

  • Passport photocopy (required for permit registration)
  • Emergency cash in Indonesian Rupiah
  • Phone in a waterproof bag or case
  • Portable power bank — there is no electricity on the mountain
  • Small daypack (25–30L) for the summit push, separate from your main bag

What NOT to Bring

  • Heavy jeans or cotton clothing — they absorb moisture and become dangerously cold
  • Glass bottles — banned in the national park
  • Single-use plastic beyond what's necessary — leave no trace
  • Valuables or excessive electronics

Pack light but pack smart. Your porters will thank you, and your knees will too.
