What to Pack for Inner Basin Trailhead, Coconino

Preparation starts with your pack. Here's what to bring.

Preparation for Inner Basin starts with your pack. These items address the real risks and conditions here.

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

  • Bear canister — A hard-sided canister protects your food from raccoons, rodents, and other camp raiders too, not just bears.
  • Bear spray — Bear spray works on all bear species; keep it in a hip holster for instant access, not buried in your pack.
  • Bear bell — On windy trails or near streams where your voice might not carry, a bear bell provides constant, passive noise.
  • 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.

Climate Gear

  • Insulated layers — Layering lets you regulate temperature as conditions change, preventing the sweat buildup that causes chills later.
  • Hand warmers — Beyond comfort, hand warmers can help treat mild hypothermia by warming blood flowing through the extremities.
  • Thermos — A thermos also works in reverse: cold water stays cold in summer heat, encouraging steady hydration.

Terrain Gear

  • Headlamp (extra) — A second light source is a fundamental safety redundancy in backcountry travel where help may be hours away.
  • Emergency bivy — In remote terrain where rescue may take hours or overnight, a bivy sack can prevent hypothermia in survivable conditions.
  • PLB/satellite messenger — Two-way satellite messengers also let you send check-in messages, reducing worry for contacts at home.

Seasonal Gear

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