01Why Winter Camp?
Winter camping lets you access remote terrain beyond day-trip distance, camp where conditions are best (no hut reservations), find solitude and pristine snow, and link multi-day traverses and expeditions.
02Shelter Options
Four-season tent: fast (15-30 min), reliable, reusable, but heavy (2-4kg) and can be cold in high wind. Choose a geodesic dome with strong poles, a large vestibule, snow flaps, and good venting.
Snow shelters (quinzee, igloo, snow cave): no weight to carry, excellent insulation (near 0°C inside), complete wind protection — but take 1-4 hours to build and need the right snow and skills.
Hybrid: pitch a tent and build snow walls around it for wind protection.
Snow holds heat. Nylon does not.
Illustrative overnight model. Snow shelters latch near 0°C because the surrounding snowpack buffers heat; fabric shelters track the air, gaining only a few degrees from body heat. Always carry a bag rated below your coldest expected night. Educational only.
03Essential Gear
Sleeping: bag rated -15°C to -25°C comfort and a pad with R-value 5+ (or two pads).
Cooking: liquid-fuel stove (reliable in cold) with a windscreen; plan 200-250ml fuel per person per day; a 2-3L pot for melting snow.
Also: a larger snow shovel and saw (platform/shelter), a clearly-marked pee bottle, dry-bag stuff sacks, repair kit, and extra batteries kept warm.
04Water & Food
Water: melting snow is slow (~15 min/L) — plan 3-4L per person per day. Keep bottles from freezing (insulated, upside-down, in the bag overnight); a hot water bottle gives warmth and morning water.
Food: expect 4000-5000 calories/day. Hot quick breakfasts, high-calorie no-cook lunches/snacks (nuts, chocolate, cheese, salami), substantial hot dinners, and a fatty snack before bed for overnight warmth.
Every litre of water is melted — and it costs fuel and time
Two bottles — carry the spare; run the fuel dry and the trip ends.
Illustrative provisioning model. There is no liquid water in winter: each litre is melted snow, and fuel is derived from litres melted (≈64 mL per L). Plan your own margin. Educational only.
There is no tap in the backcountry: every drink is melted snow, and melting is what burns your fuel. At ~15 min and ~64 mL of fuel per litre melted, a 2-person party over 4 nights melts 28 L — about 7 hours of stove-time and ~1.8 L of fuel, which rounds up to two 1-litre bottles. Provision the consumables, not just the route: run the fuel dry and the trip ends.
05Camp Site & Routine
Site selection: avoid camping below avalanche paths (check overhead hazard), shelter from wind, ensure sufficient snow depth for anchors/shelter.
Routine: arrive with 2+ hours of daylight, build a platform, pitch and anchor, organize gear, melt water. Evening: change into dry layers, brush off all snow, cook, hydrate, and keep boot liners/skins/bottles in your sleeping bag overnight to prevent freezing.
06Progression
Build skills progressively: practice at home, then winter car-camp, then a single night near the trailhead, then weekend trips, then extended remote tours. Common challenges: condensation (ventilate), cold (eat fat before bed, hot water bottle), and keeping gear from freezing.

Key takeaways
- Choose your shelter by snow and skill: tents are fast and reliable; snow shelters insulate better but take hours to build.
- Pair a -15°C to -25°C bag with an R-value 5+ pad (or two pads) to stay warm against the snow.
- Melt 3-4L of water per person per day, budget 200-250ml of fuel, and eat 4000-5000 calories including fat before bed.
- Pick camp sites for avalanche safety and wind protection, and keep boot liners, skins, batteries, and bottles in your bag overnight.
- Build skills progressively — practice at home, then car camp, then single nights, before remote multi-day trips.
Frequently asked questions
What temperature sleeping bag do I need?+
Aim for a comfort rating of -15°C to -25°C depending on conditions, paired with a pad of R-value 5 or higher. Two pads and a liner add warmth.
How much water and fuel per day?+
Plan 3-4 litres of water per person per day and 200-250ml of stove fuel per person per day, more if melting all water from snow. Carry extra fuel for a margin.
Tent or snow shelter?+
A four-season tent sets up fast and is reliable but heavier and colder in wind. Snow shelters carry no weight and block wind well but take 1-4 hours and need the right snow. A tent-plus-snow-walls hybrid combines both.
