Packing for a backpacking trip is part science, part art. Pack too much and your knees will hate you; pack too little and you'll be cold, hungry, or unsafe. This checklist covers the essentials for every season.
Core Gear (Every Season)
Shelter
- Tent or tarp: A quality three-season tent works for most trips (2-4 lbs)
- Groundsheet or footprint: Protects your tent floor and can serve as a backup shelter
- Stakes and guylines: Always carry extras
Sleep System
- Sleeping bag: Rated 10-20°F below your expected low temperatures
- Sleeping pad: R-value 3+ for three-season use, R-value 5+ for winter
- Pillow: Inflatable or stuff sack filled with clothes
Cooking
- Stove and fuel: Canister stoves are lightest; liquid fuel stoves work better in cold
- Pot and utensil: A 750ml pot handles most solo meals
- Water treatment: Filter, chemical treatment, or UV purifier
- Water bottles/bladder: 2-3 liter capacity minimum
Navigation
- Map and compass: Always carry physical backup
- GPS device or phone with offline maps: Download trail maps before you leave service
- Trail description/guidebook: Know your route before you go
Safety
- First aid kit: Blister care, pain relief, wound care, medications
- Headlamp with spare batteries
- Emergency shelter: Lightweight bivy or space blanket
- Whistle and signal mirror
- Satellite messenger: Recommended for remote areas
Summer Additions
- Sun protection: Hat, sunscreen (SPF 50+), sunglasses, lip balm with SPF
- Bug protection: Head net, insect repellent (DEET or picaridin), permethrin-treated clothing
- Lighter sleeping bag: 30-40°F rated bag saves weight
- Quick-dry clothing: Avoid cotton; synthetics and merino wool dry fast
- Extra water capacity: Summer heat means higher water needs
Fall Additions
- Warmer sleeping bag: 20°F rated for shoulder-season nights
- Insulation layer: Lightweight down or synthetic puffy jacket
- Wind protection: Wind shirt or softshell
- Warm hat and lightweight gloves
- Rain gear: Fall weather can be unpredictable
Winter & Cold Weather Additions
- Four-season tent or mountain shelter
- Winter sleeping bag: 0°F or lower
- High R-value pad: R-value 5+ is essential; consider doubling up
- Insulated water bottles: Prevent freezing
- Avalanche safety: Beacon, probe, shovel (if traveling in avalanche terrain)
- Traction devices: Microspikes or crampons
- Snowshoes or skis: Depending on conditions
- Extra fuel: Cold weather increases fuel consumption
Spring Additions
- Waterproof layers: Spring means rain and snowmelt
- Gaiters: Keep feet dry during stream crossings and muddy trails
- Trekking poles: Essential for snow crossings and swollen creek crossings
- Traction devices: Snow lingering on north-facing slopes and passes
Packing Tips
- Use a packing list every time. Even experienced backpackers forget things.
- Lay everything out before packing. Eliminate duplicates and unnecessary items.
- Weigh your pack. Aim for a base weight (before food and water) under 20 lbs for three-season trips.
- Prioritize the "big three." Your tent, sleeping bag, and backpack account for most of your weight. Investing in lighter versions has the biggest impact.
