Day Hike Checklist: What to Bring on a Day Hike
Updated October 2026 · 3 min read
Quick answer
On every day hike, bring water, snacks, a rain jacket and a warm layer, sun protection, a map or offline map app, a headlamp, a small first aid kit, a knife or multitool, a fire starter, and an emergency blanket — and tell someone where you're going.
Most day hikes go exactly as planned. The gear in your daypack is there for the times they don't — a wrong turn, a twisted ankle, a storm, or a hike that runs past sunset. This checklist is based on the classic Ten Essentials that hiking clubs and rangers recommend, kept simple for day trips.
The Ten Essentials
| Essential | What to bring |
|---|---|
| 1. Navigation | Map, compass, or phone with offline maps |
| 2. Light | Headlamp with spare batteries |
| 3. Sun protection | Sunglasses, sunscreen, hat |
| 4. First aid | Small kit with blister care |
| 5. Knife | Knife or multitool |
| 6. Fire | Lighter or waterproof matches |
| 7. Emergency shelter | Emergency blanket or bivy |
| 8. Extra food | More than you plan to eat |
| 9. Extra water | Enough water, or a way to treat it |
| 10. Extra clothes | Rain jacket and warm layer |
Most of these fit in a small pouch and weigh little. Pack them once and leave them in your daypack.
Water and food
A common guideline is about half a liter (17 oz) of water per hour of moderate hiking, more in heat or on steep climbs. For a 4-hour hike that's around 2 liters — and bring a little extra.
- Water bottles or a hydration bladder — see hiking water bottles and hydration bladders.
- A filter or filter bottle on longer hikes with streams — see water filters for hiking.
- Salty and sweet snacks — trail mix, bars, jerky, fruit. Eat a little every hour.
- Electrolytes on hot days.
Clothing and footwear
- Hiking shoes or boots that are already broken in — see boots vs shoes.
- Moisture-wicking socks, plus a spare pair on long or wet hikes.
- A rain jacket, even with a sunny forecast. See best rain jackets.
- A warm layer like a fleece or light puffy.
- A hat and sunglasses. See hiking hats.
Safety and first aid
- First aid kit with bandages, blister pads, pain relievers, and any personal medication. See hiking first aid kits.
- Headlamp — hikes take longer than planned. See headlamps for hiking.
- Whistle — three blasts is the standard call for help. See emergency whistles.
- Emergency blanket — weighs almost nothing. See emergency blankets.
- Knife or multitool and a lighter.
Nice to have
- Trekking poles for steep or long hikes — see do you need trekking poles.
- Insect repellent.
- A sit pad, a small trash bag, and toilet paper with a zip bag to pack it out.
- A waterproof phone case.
What to carry it in
A 15–30 liter daypack holds everything above. Look for a hip belt if you carry more than a few pounds, and a sleeve for a water bladder. See best daypacks and how to choose a backpack size.
Before you leave home
- Tell someone your trail, your plan, and when you'll be back.
- Check the weather for the trailhead and summit, not just the nearest town.
- Know the sunset time and plan to finish before it.
- Check trail conditions and any closures or permit rules.
- Set a turnaround time — and stick to it.
