Mount Rinjani Packing List: The Complete Checklist

Before packing, clarify exactly what your trek operator includes. A standard package typically provides:

Standard inclusions: Tent (shared 2-person), sleeping bag, sleeping mat, all meals (breakfast, lunch, dinner, snacks), drinking water (at least 3 liters per day), porter to carry group equipment and food, registered guide, cooking equipment and utensils, and first aid kit.

Not typically included (you must bring): Daypack, personal clothing, headlamp, trekking poles, personal medications, toiletries, camera, snacks beyond what the operator provides, sleeping bag liner (for extra warmth), and rain jacket.

Varies by operator: Some mid-range and premium operators also provide trekking poles for rent (50,000-100,000 IDR), extra water beyond the standard allocation, and higher-quality sleeping bags. Ask specifically about sleeping bag temperature ratings — this significantly affects your comfort and sleep quality at the rim camp.

Tip: Request to see the equipment before your trek day if possible. Check the sleeping bag's loft (fluffiness indicates warmth), the tent's waterproofing, and the condition of the sleeping mat. If the gear looks inadequate, supplement with your own.

The key to comfort on Rinjani is layering. You will experience temperatures from 30°C in the forest to near-freezing at the summit. Here is the layering system:

Base layer: Moisture-wicking shirt (synthetic or merino wool). Cotton absorbs sweat and stays wet, making you cold. Bring 2 shirts — one for hiking, one dry for camp/sleeping.

Mid layer: Lightweight fleece or synthetic insulation jacket. This is your warmth layer for the rim camp and the first hours of the summit push. A fleece pullover weighing 200-300 grams is ideal. Bring one.

Outer layer (summit trek): A lightweight down jacket or puffy jacket for the summit push and morning hours at the rim. This provides critical warmth when standing still in the cold at 3,000+ meters. Even for the 2-day trek, the rim camp evening can be cold enough to want a warm jacket.

Rain layer: Waterproof jacket that packs small. Even in dry season, rain can occur on the mountain. A rain poncho works as a budget alternative but does not protect as well.

Bottoms: Lightweight hiking pants (quick-dry material). Zip-off pants that convert to shorts are ideal for the temperature range. Bring one pair plus a pair of comfortable pants for sleeping. Avoid jeans — they are heavy, do not stretch, and take forever to dry.

Extras: Warm hat or beanie (essential for summit morning). Buff or neck gaiter (wind protection for the face). Lightweight gloves (hands get cold at altitude). Underwear changes for each day. Warm socks for sleeping — your feet get cold at night.

Your footwear choice is one of the most important decisions for Rinjani:

Primary hiking shoes: Mid-cut hiking boots with ankle support, grippy Vibram or similar rubber soles, and some waterproofing. The trails involve loose rock (especially the summit scree), mud (in the forest section), and steep descents where ankle support prevents rolls and sprains. Lightweight hiking boots in the 700-900 gram range per boot are the sweet spot.

Break them in. New boots cause blisters. Wear your hiking boots for at least 2-3 weeks of regular walking before the trek. If you cannot break them in, consider well-worn trail runners with good grip as an alternative — less ankle support but no blister risk.

Camp shoes: Lightweight sandals or flip-flops for wearing around camp. After 8 hours in hiking boots, your feet need a break. These also serve as shower shoes. Keep them light — every gram counts.

Socks: Merino wool hiking socks are the gold standard — they wick moisture, prevent blisters, and retain warmth when damp. Bring 2-3 pairs (one per day plus a spare). Inner liner socks add an extra blister-prevention layer. Avoid cotton socks.

Headlamp: Non-negotiable. Bring a reliable headlamp with fresh batteries and at least one set of spare batteries. For the summit push (starting at 2 AM in total darkness), the headlamp is your primary tool. A dim or dead headlamp turns the scree ascent from challenging to dangerous. LED headlamps with 200+ lumens are ideal.

Daypack (30-40 liters): Your porter carries the group equipment; you carry your personal gear in a daypack. A comfortable, well-fitting pack with a hip belt distributes the 5-8 kg load across your body. Pack a waterproof liner or drybag inside to protect contents from rain.

Trekking poles: Highly recommended, especially for the descent. Poles reduce knee impact by 20-30% on steep downhill sections and provide balance on loose terrain. Telescoping aluminum poles pack small when not in use. If you do not own poles, ask your operator about rental.

Water bottles/bladder: Carry 3 liters of water capacity. A hydration bladder in your pack plus a backup bottle works well. Your operator provides water at camps, but you need to carry enough for the trail between stops. On the summit push, carry at least 1.5 liters — dehydration at altitude amplifies fatigue and altitude symptoms.

Sunscreen (SPF 50+) and hat: The Sembalun route crosses open savanna with zero shade. At altitude, UV radiation is more intense. Apply sunscreen before departing each morning and reapply at rest stops. A wide-brimmed hat or cap with neck flap protects your face and neck.

Sunglasses: Useful for the bright, exposed sections and essential if there is snow near the summit (rare but possible).

Camera: Bring a camera or ensure your phone is fully charged. The views from the rim and summit are extraordinary and you will want to capture them. Bring a power bank — cold temperatures drain batteries faster than normal.

Operator-provided meals: Typically simple but adequate — nasi goreng (fried rice), mie goreng (fried noodles), eggs, bread, soup, fruit, and tea/coffee. Porters carry cooking equipment and prepare meals at camp. The quality and variety depends on the operator — premium operators serve noticeably better food.

Personal snacks: Supplement operator meals with your own high-energy snacks for the trail. Trail mix, energy bars, chocolate, dried fruit, and biscuits are all good options. Buy these in Kuta Lombok or Mataram before the trek — selection near the trailhead is limited. Carry 4-6 snack items per day.

Hydration strategy: Drink at least 3 liters per day — more on the summit day. Water is heavy (1 kg per liter), so refill at camps rather than carrying your entire day's supply from the start. Add electrolyte powder or rehydration salts to one bottle per day — you sweat heavily on the lower slopes and the mineral replacement helps prevent cramping.

Blister kit: Moleskin patches, medical tape, and blister pads. Apply at the first sign of a hot spot — do not wait until a full blister forms. Prevention is easier than treatment. Also carry small scissors for cutting moleskin.

Pain relief: Ibuprofen or paracetamol for headaches (common at altitude) and muscle soreness. Take as needed, not preemptively.

Altitude medication: Diamox (acetazolamide) can help prevent altitude sickness symptoms. Consult your doctor before the trek if you are concerned about altitude. Not essential for most trekkers but useful for those with a history of altitude sensitivity.

Stomach medication: Loperamide (Imodium) for diarrhea — the last thing you want on a mountain trail. Antacids for upset stomach. Water purification tablets as backup.

Wound care: Antiseptic wipes, small bandages, and gauze. Scrapes and cuts from rock and trail are common.

Personal medications: Bring any prescription medications you take regularly, plus a day's extra supply in case of delays.

Toilet supplies: Toilet paper (your operator may not provide enough), hand sanitizer, wet wipes, and a ziplock bag for carrying used toilet paper out (leave no trace).

The 3-day summit trek requires additional items beyond the 2-day list:

Warmer layers: The summit push at 2-3 AM in near-freezing temperatures demands a warmer clothing system. A proper down jacket (not just a fleece), warm gloves (not just liner gloves), a beanie that covers your ears, and thermal base layer bottoms.

Hand and toe warmers: Disposable chemical warmers that provide heat for 6-8 hours. Invaluable for the summit push when hands and feet get painfully cold. Available in outdoor shops — buy before arriving in Lombok.

Extra batteries: The cold dramatically reduces battery performance. Keep headlamp batteries and phone power bank inside your jacket (body heat preserves charge). Bring double the batteries you think you need.

Balm or Vaseline: Apply to lips and exposed facial skin to prevent windburn during the summit push. The cold, dry wind at altitude cracks lips painfully.

Too many clothes. You need fewer changes than you think. Rewearing hiking clothes that smell is normal on multi-day treks. Three shirts, two pants, and three pairs of socks covers any Rinjani trek.

Heavy books or electronics. Every gram matters. An e-reader is fine; a laptop is absurd. Leave non-essential electronics at your accommodation.

Valuables. Leave jewelry, expensive watches, and unnecessary cash at your hotel safe. Bring only what you need — phone, camera, and enough cash for tips and emergencies (200,000-300,000 IDR).

Cotton clothing. Cotton absorbs moisture, stays wet, and makes you cold. Replace all cotton items with synthetic or merino wool alternatives.

Alcohol. Do not bring alcohol on the trek. It dehydrates you, impairs judgment at altitude, and is disrespectful to the local Sasak guides (Lombok is majority Muslim). Save the beer for your post-trek celebration in Kuta.
