What to Pack for Pearl Harbor National Wildlife Refuge #2 (NE, 2mi), Honolulu

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

Preparation for Pearl Harbor National Wildlife Refuge 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.
