What to Pack for Bear Pen Springs Trail, Greenlee

Pack with the terrain and wildlife in mind, and you'll be ready for anything here.

A well-prepared pack for Bear Pen Springs covers 3 categories: essential, wildlife gear, terrain gear.

Essential

  • Water (minimum 2L) — Even cool-weather hiking demands steady hydration, as exertion and altitude increase water loss faster than most expect.
  • Navigation (map/GPS/compass) — Even well-marked trails have confusing junctions, especially in fog or snow; a GPS unit or downloaded map keeps you on route.
  • Sun protection (sunglasses, sunscreen) — Quality sunglasses prevent snow blindness and reduce eye strain during long days on exposed trails or ridgelines.
  • First aid kit — Adhesive bandages, antiseptic, and athletic tape handle the most common trail injuries and weigh under a pound.
  • Extra food — Blood sugar drops fast during sustained effort outdoors, and having a reserve keeps your body and mind sharp.
  • Headlamp with extra batteries — Batteries drain faster in cold weather; carrying spares ensures you won't be left in the dark when you need light most.
  • Fire starter — Starting a fire boosts morale and provides light, warmth, and a way to purify water in an emergency.
  • Emergency shelter (space blanket) — If an injury forces you to stop moving, a reflective blanket prevents the rapid heat loss that leads to hypothermia.
  • Knife or multi-tool — In a survival situation, a blade lets you process tinder, build shelter, and prepare food.
  • Extra clothing layer — Wet clothing accelerates cooling; a dry backup layer can prevent hypothermia when conditions turn.

Wildlife Gear

  • Hiking buddy (avoid solo) — Solo hikers are more vulnerable to predatory behavior from mountain lions, which typically avoid groups.
  • Noise maker — A loud whistle doubles as a rescue signal, serving both wildlife safety and emergency communication.
  • Gaiters — Beyond snakes, gaiters also protect against thorns, brush, and ticks in overgrown trail sections.
  • First-aid snakebite kit — A lightweight pressure bandage and marker for tracking swelling take up minimal space but provide critical aid.

Terrain Gear

  • Trekking poles — Trekking poles also serve as emergency splint supports, tarp poles, or probes for testing snow depth.
  • Ankle-support boots — Stiff soles transfer less impact on rocky terrain, reducing foot fatigue over long distances.

Seasonal Gear

  • Spring: Camera, Wildflower field guide
  • Fall: Camera, Binoculars (foliage viewing)
