Essential Gear & Permits

Must-Have Essentials

  • Timed entry permit for peak season (required)
  • Altitude sickness medication (consult doctor)
  • Sunscreen SPF 50+ (UV is intense at altitude)
  • Waterproof layers (afternoon thunderstorms daily in summer)
  • Bear canister for backcountry
  • Trekking poles for scrambles
  • Extra warm layers

What to Wear

Clothing & Footwear

  • Moisture-wicking base layers (top and bottom)
  • Down or fleece mid-layer
  • Waterproof, breathable shell jacket and pants
  • Warm hat and gloves (temperatures can be 30°F on summits even in July)
  • Wool socks 3 pairs
  • Waterproof hiking boots

Gear & Equipment

Backpacking & Camping Gear

  • GPS or downloaded offline maps (trail junctions can be confusing)
  • Headlamp with extra batteries
  • Sleeping bag rated to 20°F for backpacking
  • Tent rated for wind — above treeline gets brutal
  • Water filter

Food & Nutrition

Food Planning

  • High-calorie snacks (altitude suppresses appetite but increases calorie burn)
  • Warm breakfast food for cold mornings
  • Electrolytes
  • Extra day's food as emergency reserve

Safety Tips for Rocky Mountain

Altitude sickness can hit at 8,000+ ft — take 2 days to acclimatize

Get above treeline before noon to avoid lightning — storms hit fast and violently

Hypothermia risk even in summer — temperatures can drop 30°F in an hour

Elk rut in September — bull elk are aggressive near trails
