Essential Gear & Permits

Must-Have Essentials

  • Timed entry permit for peak season (required)

What to Wear

Clothing & Footwear

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

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
