Stop 5- Puʻuloa Petroglyphs, Hawaiʻi Volcanoes NP

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.
