Pack for the cold you don't expect · 2026

Rinjani packing list: summit-night layers, rim cold, and what we already carry for you.

The mistake people make is over-packing things we provide and under-packing for the cold. Here's exactly what to bring, what to leave, and what we carry up so you don't have to.

Written by Pak Wil · Senaru, Lombok · Updated 2 June 2026

01 · So you don't double-pack

What we already carry up

Start here, because half of what packing lists tell you to bring, we already carry. Don't double up.

04Tent, mat & sleeping bagrated for the rim cold
IncludedA 3-season tent, a sleeping mat, and a sleeping bag warm enough for a normal night at the rim, pitched and waiting when you reach camp. We don't print a comfort rating for the bags, because Pak Wil doesn't have one from the supplier and we won't invent a number. If you know you sleep cold, bring a thermal base layer and a beanie.
05Three cooked meals a day
IncludedHot breakfast, lunch and dinner on the mountain, plus tea before the summit push.
06Coffee, tea & drinking water
IncludedAt every stop. You don't carry days of water. We refill you along the way.
07Hotel pickup
IncludedFrom your hotel in Senaru or Sembalun to the trailhead, and back at the end.
08Trekking poles
On requestWe'll bring poles for you, just tell Pak Wil when you book. Your knees will thank you on the descent.

Don't pack a tent, a bag, or a stove. Pack the layers. That's the part only you can get right.

What your porters carry, and the loads we cap
02 · The part that matters

Summit-night kit, layer by layer

This is the section to get right. You leave camp around 2 a.m. into wind and cold, and you dress in layers you add and shed as the sun comes up. Bring all of it.

Top half

Three layers, worn together at 2 a.m.

01Base layernext to skin
A thermal top and leggings, merino or synthetic, not cotton. Cotton holds sweat and turns cold; it's the one fabric to leave at home.
02Mid layeryour warmth
A fleece or a light down jacket, the layer you actually climb in for the first cold hour out of camp.
03Shellwindproof
A windproof jacket over the top. The summit wind is the thing that gets people, not the air temperature. Wind chill can feel like −5°C even in dry season.
Legs & extremities

The bits that go numb first

04Legs
Trekking trousers, with the thermal leggings underneath them for the 2 a.m. push. You'll be glad of the second layer above the treeline.
05Hands, head & neck
A warm hat, gloves (windproof if you have them), a buff or neck gaiter, and thick socks. Small things, but they're what go numb first.
06Headlamp + spare batteries
Can loanYou walk the summit in the dark. A phone torch won't do. We can loan a headlamp; tell Pak Wil, but bring your own if you can.
07Snacks you actually like
The cold kills your appetite, and you'll want something familiar. Bring the bar or sweet you'd reach for at home, not what looked rugged in the shop.

You'll put on every layer you brought at 2 a.m., and take them all off by 9.

Sleeping warm at the crater rim

These are operator estimates, given as typical ranges, not guarantees. Nights up there vary a lot, so pack for the cold end and ask Pak Wil what he'd bring for your month.

Crater rim camp~2,600 m
Typical nightPak Wil's read: 10-20°C on a normal night
Coldest · dry-season clear nightsCan come as low as ~5°C before dawn. The rim does not normally hit 0°C, but pack for the cold end, not the average.
Summit, pre-dawn3,726 m
Typical nightaround 0-5°C
Coldest · dry-season clear nightsAt or below freezing on clear nights; wind chill can feel like −5°C.

We give you a 3-season tent, a mat, and a bag warm enough for a normal rim night. Pak Wil has no comfort rating from the supplier, so we won't print one, but the bag handles a normal night at the rim on its own.

If you know you sleep cold, the fix is small: bring a thermal base layer to sleep in and a beanie. That's the difference between a rough night and a fine one. The coldest nights of the year are July to August.

How cold it gets, month by month
04 · The honest one

Footwear: boots or trail runners

There's no single right answer here, and anyone who tells you there is hasn't done both. Here's the honest trade-off.

Option A

Hiking boots

Ankle support on the loose scree near the summit, and on the long descent when your legs are tired and your footing gets sloppy. Stiffer, warmer, heavier.

Best if you're not a confident downhill walker, or you've rolled an ankle before.

Option B

Trail runners

Lighter and quicker, and plenty of experienced trekkers do Rinjani in them. Less ankle support, so more is asked of your own balance, especially on the scree.

Best if you're experienced on trails and your knees and ankles are good.

Whichever you pick, the Senaru and Torean descents are long and steep, hard on the knees either way. Break your shoes in before you fly; the summit is no place to discover a hot-spot. If you'd rather not travel with boots, we rent trekking shoes in Senaru for about IDR 100,000 to 150,000.

Why the descent is where knees complain
05 · What goes where

Daypack vs porter bag

Two bags: a small daypack on your back, and a main bag the porter carries. The trick is packing them so you're never reaching for something that's an hour up the trail.

On you · daypack

  • Water for the stretch ahead, and your summit layers
  • Headlamp, snacks, sunscreen and a hat
  • Camera or phone, and your valuables: passport, cash, cards
  • A light rain layer, just in case the cloud builds

Porter carries · main bag

  • Your spare clothes and your sleep base layer
  • The change of clothes for after the summit and at camp
  • Toiletries, charger, anything you don't need while walking
  • The tent, mat and sleeping bag, those are ours, already up there

Pack your main bag so the porter isn't carrying your day-essentials uphill and back down again, and so it stays within our porter load limit. We keep loads under the park's 30 kg limit for a reason, lighter where we can.

What to leave, and what to rent in Senaru

You don't need to buy a full kit for one mountain. Bring the layers; the bulky stuff you can sort here.

Leave behind

Drop it at our office

The wheelie suitcase, your clean clothes for after the trek, and anything you don't want on the mountain: leave it at our office in Senaru and pick it up when you come down. We store it safely for the whole trek.

Forgot something?

Rent it in Senaru

If you've left kit at home, you can rent it from us in the village rather than carry gear across Indonesia for one climb. Rough 2026 rates per item: trekking shoes IDR 100,000 to 150,000, a jacket IDR 50,000 to 100,000, a day backpack IDR 50,000 to 100,000, trekking poles IDR 60,000 a pair, a headlamp IDR 20,000.

Tell Pak Wil before you arrive what you're missing, and he'll tell you whether to pack it, rent it, or leave it to us.

Sorting your gear means you're getting close

Tell Pak Wil your month and he'll confirm exactly what we provide for your route, so you only pack what's actually yours to bring.

Already booked? Forward this list to your trek-mate. He answers his own WhatsApp, 07:00-21:00 WITA.

Quick packing questions

Do I need to bring a sleeping bag?
No, we provide a 3-season tent, a sleeping mat, and a sleeping bag rated for the rim cold, all pitched and waiting at camp. If you know you sleep cold, bring a thermal base layer to sleep in and a beanie. More on sleeping warm →
How cold does it really get?
Pak Wil's read is that a normal night at the crater rim camp (~2,600 m) sits around 10-20°C. It can come as low as ~5°C before dawn on the clearest dry-season nights, though the rim doesn't normally hit freezing. The summit, pre-dawn, is the cold one: around 0-5°C, at or below freezing on clear nights, with wind chill that can feel like −5°C. The coldest nights are July to August. Pack for the cold end, and ask Pak Wil what he'd bring for your month. See the temperature table →
Boots or trail runners?
Both work. Boots give you ankle support on the scree and the long descent; trail runners are lighter and fine if you're experienced and your knees are good. The descents are hard on the knees either way, so break in whatever you bring. The honest trade-off →
Can I leave my big bag somewhere?
Yes, leave the wheelie suitcase and your post-trek clean clothes at our office in Senaru and collect them when you come down, so you only take what you need up the mountain. We store it safely for the whole trek. Leaving & renting →
What if I forgot something? Can I rent it in Senaru?
Yes. A forgotten jacket, poles or a headlamp you can rent from us in the village: trekking shoes are about IDR 100,000 to 150,000, a jacket or a day backpack IDR 50,000 to 100,000, poles IDR 60,000 a pair, a headlamp IDR 20,000. Tell Pak Wil what you're missing and he'll set it aside.

“The people who suffer up here aren't unfit. They're cold. Pack for the wind, not the forecast.”
