What to Pack for Old Caves Crater (south) Trailhead, Coconino

Being properly equipped turns potential hazards into manageable situations.

Pack for Mountain Forest terrain, Semi-Arid, and the wildlife considerations above.

Essential

  • Water (minimum 2L) — Dehydration impairs judgment and endurance long before you feel thirsty; 2L is the minimum for a moderate day hike.
  • Navigation (map/GPS/compass) — Phone batteries die, cell service disappears, and trail signs get vandalized; a paper map and compass always work.
  • Sun protection (sunglasses, sunscreen) — UV exposure intensifies at elevation and near reflective surfaces like water and snow; sunburn can happen in under 30 minutes.
  • First aid kit — Blisters, cuts, and sprains happen on even the easiest trails; basic supplies let you treat problems before they force a retreat.
  • Extra food — A wrong turn or unexpected storm can extend any outing by hours; extra calories prevent fatigue and poor decision-making.
  • Headlamp with extra batteries — Trails that seem short in daylight can take twice as long with route-finding or elevation; a headlamp keeps you moving safely after dark.
  • Fire starter — Hypothermia can set in even during summer at higher elevations; a reliable fire starter provides warmth and a signal for rescuers.
  • Emergency shelter (space blanket) — A space blanket weighs under two ounces and reflects up to 90% of body heat, buying time in an unplanned overnight.
  • Knife or multi-tool — From cutting cord to preparing food to improvising gear repairs, a knife is the most versatile tool you can carry.
  • Extra clothing layer — Mountain weather can shift from sunshine to sleet within an hour; an extra layer prevents dangerous heat loss.

Wildlife Gear

  • Bear canister — Storing food in a bear canister prevents bears from associating humans with food, which is the leading cause of dangerous bear behavior.
  • Bear spray — Studies show bear spray stops aggressive bear behavior in over 90% of encounters, outperforming firearms in field effectiveness.
  • Bear bell — Most bear encounters happen when hikers surprise a bear at close range; a bell provides continuous noise that alerts bears to your presence.
  • Hiking buddy (avoid solo) — Groups of three or more are almost never involved in serious bear incidents; larger groups make more noise and appear more intimidating.
  • Noise maker — Clapping, whistling, or using an air horn warns wildlife of your approach, preventing surprise encounters on blind corners.
  • Gaiters — Snake-proof gaiters provide a physical barrier against venomous bites below the knee, where most strikes occur.
  • First-aid snakebite kit — While evacuation to a hospital is the priority, a snakebite kit helps you stay calm and follow proper first-aid protocols.

Climate Gear

  • Insulated layers — Body heat escapes rapidly when you stop moving; an insulated layer traps warmth during breaks and at camp.
  • Hand warmers — Cold fingers lose dexterity fast, making it harder to operate zippers, buckles, and navigation devices when you need them most.
  • Thermos — A hot drink on a cold trail restores core temperature and morale faster than any other comfort item.

Terrain Gear

  • Trekking poles — Poles reduce knee impact by up to 25% on steep descents, preventing the joint pain that slows hikers on long routes.
  • Ankle-support boots — Loose rock, roots, and uneven terrain put constant lateral stress on ankles; supportive boots prevent the sprains that end trips.

Seasonal Gear

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