What to Pack for Glover Trail, Hawaiʻi Volcanoes NP

Being properly equipped turns potential hazards into manageable situations.

Pack for Tropical terrain, variable conditions, 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.
