Glacier Hike Packing List (Gear That Actually Matters)

Temperature drops fast on the glacier

Even summer glacier hikes run 15–25°F colder than the valley. Wind chill adds another 10°F. Layers matter more than bulk — you'll heat up on the approach, freeze at elevation, then bake in the sun reflecting off ice.

Guides provide crampons and axes, usually

Most commercial glacier hikes provide technical gear — crampons, harness, ice axe. Confirm ahead. You're responsible for boots that fit crampons, which means stiff soles and ankle support. Trail runners don't work.

Sun exposure is double what you expect

Ice reflects 80% of UV radiation. You're getting burned from below and above. Sunscreen alone isn't enough — neck gaiters, glacier glasses, and lip balm with SPF are non-negotiable.

Cotton kills, even in summer

Sweat, meltwater, and rain are constant on glaciers. Cotton stays wet and pulls heat from your body. Synthetic or merino base layers dry fast and insulate when damp. This is the mistake that ends hikes early.

Clothing

• Waterproof hardshell jacket

  Wind and rain hit hard on exposed ice. Needs a hood that fits over a hat.

• Waterproof hardshell pants

  Meltwater soaks through softshells. Side zips let you vent without removing crampons.

• Insulated mid-layer (synthetic or down)

  Stops and summits get cold fast. Synthetic holds warmth when damp; down packs smaller.

• Merino wool or synthetic base layer top

• Merino wool or synthetic base layer bottoms

• Thick wool or synthetic hiking socks (2 pairs)

  One pair on your feet, one dry pair in your pack. Wet socks end hikes.

• Insulated waterproof gloves

  You'll be adjusting crampons, holding ropes, and gripping ice axes. Thin gloves don't work.

• Liner gloves

  For dexterity when you need to adjust gear without freezing your fingers.

• Warm hat (wool or synthetic)

• Neck gaiter or balaclava

  Protects against wind and reflected UV. Sunscreen alone doesn't cover enough.

Gear

• Hiking boots with stiff soles and ankle support

  Crampons require stiff soles. Trail runners flex too much and won't hold the binding.

• Waterproof gaiters

  Keep snow and meltwater out of your boots. Low gaiters don't cut it on glacier terrain.

• Glacier sunglasses (Category 3 or 4)

  Regular sunglasses let in too much reflected light. Snow blindness is real and painful.

• 30–40L daypack

  Big enough for layers, water, and snacks. Needs external attachment points for an ice axe if you're carrying your own.

• Trekking poles (optional but useful)

  Help with balance on uneven ice and take strain off your knees on the descent.

• Lightweight dry bag or trash bag

  Keeps your dry layers and electronics safe if your pack gets soaked.

Electronics

• Headlamp with extra batteries

  Glacier hikes start early or run long. Cold drains batteries fast.

• Phone or camera in waterproof case

  Meltwater and condensation kill electronics. A case or ziplock bag works.

• Portable battery pack

  Cold drains phone batteries. Keep it warm in an inner pocket.

Toiletries

• High-SPF sunscreen (50+)

  UV reflection from ice doubles exposure. Reapply every 90 minutes.

• Lip balm with SPF 30+

  Lips burn and crack fast on glaciers. Regular chapstick doesn't protect.

Other

• 1.5–2 liters of water

  Altitude and exertion dehydrate you faster than you expect. Don't rely on melting snow.

• High-calorie snacks (nuts, bars, chocolate)

  Cold burns calories. Bring more than you think you need.

• Small first aid kit

  Blisters, cuts from crampons, and headaches are common. Pack blister tape, pain relievers, and bandages.
