What to Pack for Coastal Trail, Puʻuhonua O Hōnaunau NHP

A well-packed bag handles most of what this area can throw at you.

Between the Tropical terrain and local wildlife, your pack for Coastal Trail needs a few specific items.

Essential

Water (minimum 2L) — Water sources marked on maps may be seasonal or dry; carrying enough to complete your route prevents a dangerous shortfall.
Navigation (map/GPS/compass) — Getting lost is the leading cause of backcountry search-and-rescue calls; reliable navigation prevents the situation entirely.
Sun protection (sunglasses, sunscreen) — Prolonged sun exposure causes headaches, fatigue, and heat exhaustion that can cut a trip short or create a medical emergency.
First aid kit — Remote locations mean longer response times for help; a first aid kit bridges the gap between injury and professional care.
Extra food — High-energy snacks weigh little but provide crucial fuel if you need to bushwhack out or wait for conditions to improve.
Headlamp with extra batteries — Hands-free light is essential for navigating uneven terrain, setting up camp, or signaling for help at night.
Fire starter — Waterproof matches or a ferro rod weigh almost nothing and can be the difference between a cold night and a survivable one.
Emergency shelter (space blanket) — Wind and rain strip heat faster than most people realize; a compact emergency shelter blocks both.
Knife or multi-tool — A multi-tool handles problems you can't predict: jammed zippers, tangled line, first-aid tape cutting, or gear fixes on the trail.
Extra clothing layer — A lightweight fleece or puffy stuffs small but provides critical insulation if temperatures drop unexpectedly.
