Day hike packing checklist: the Ten Essentials and more
Most day hikes go exactly as planned. The packing list exists for the ones that don’t: a wrong turn, a twisted ankle, a storm that rolls in two hours early, or a sunset that catches you a mile from the trailhead. A short checklist turns those moments into inconveniences, not emergencies.
This guide adapts the Ten Essentials for a day on the trail. We built it from The Mountaineers’ Ten Essentials, the National Park Service list and park-specific safety pages from the NPS. Where we name a product, we used the maker’s own specifications. We have not run our own field test of these items.
Where the Ten Essentials come from
The list started with The Mountaineers, the Seattle-based outdoor club, in its climbing courses of the 1930s. It was formalized in 1974 in the third edition of Mountaineering: The Freedom of the Hills and has been updated since into a “systems” approach. The Mountaineers frame it around two questions: can you prevent an emergency and respond well if one happens, and can you safely spend an unplanned night outside?
Day hikers tend to skip that second question. The Mountaineers also stress that the list is a guide to tailor: weather, distance from help and the difficulty of the route should decide how much you carry.
The Ten Essentials for a day hike
1. Navigation
Carry a map and know how to use it. The Mountaineers recommend a printed topographic map in a plastic bag as backup, even if your phone is your main tool, plus a compass. If you navigate by phone, download offline maps before you leave and bring a charged battery pack. Unless you are certain of coverage, assume your phone will not make calls in the backcountry. For remote trails, The Mountaineers suggest strongly considering a personal locator beacon (PLB) or satellite messenger.
2. Headlamp
Even if you plan to be back by mid-afternoon, pack a headlamp. The Mountaineers say every member of a party should carry one, and Yosemite’s hiking safety page recommends one on every hike, short day hikes included. Look for a weatherproof model and carry spare batteries or start with a full charge.
A simple option: the Black Diamond Spot 400 headlamp. Black Diamond lists 400 lumens maximum, 86 g (about 3 oz) with AAA batteries, an IPX8 waterproof rating and an optional BD 1500 rechargeable battery sold separately. Its red light has its own dimming mode, and a lock mode stops it turning on inside your pack.
3. Sun protection
Sunglasses, a hat, sun-protective clothing and sunscreen. The Mountaineers recommend a broad-spectrum sunscreen rated at least SPF 30, applied about 20 minutes before sun exposure and reapplied when you can. They also suggest replacing sunscreen once it is expired or more than three years old, and using an SPF lip balm.
For a daypack, a travel-size tube is enough: Sun Bum Original SPF 30 Sunscreen Lotion. Sun Bum describes it as UVA/UVB protection, water resistant for 80 minutes and made without oxybenzone and octinoxate. It comes in a 3 oz travel size.
4. First aid
A compact kit, plus the knowledge to use it. The Mountaineers’ basic kit includes bandages, gauze, tape, antiseptic, blister supplies, gloves, tweezers, over-the-counter pain relievers and antihistamines, and any personal prescriptions. Add anything specific to you, and check expiration dates, as the NPS advises. The Mountaineers also recommend wilderness first aid training, since help in the backcountry can be hours away.
A ready-made starting point is the MyMedic Wilderness Medic. MyMedic lists it at 12.5 oz and 7.5 x 5.25 x 3.5 inches, with more than 70 supplies, small modules for hydration, blister care, sting relief and bug defense, EMT shears, wound closure strips and an elastic bandage, all in a water-resistant ripstop bag. Add your own medications.
5. Knife and repair kit
A small knife or multitool, plus a few repair items: a strip of duct tape wrapped around a trekking pole or water bottle, a bit of cord and a couple of safety pins.
6. Fire
A lighter or waterproof matches and a firestarter, for warmth and signaling in an emergency only. The NPS reminds hikers to check local fire regulations first.
7. Emergency shelter
This is the item most day hikers leave behind. A rain jacket does not count. The Mountaineers note that basic space blankets do a poor job of blocking wind and rain, and suggest a heat-reflective emergency bivy instead.
The SOL Emergency Bivvy with Rescue Whistle is a common choice. SOL says it weighs less than 4 oz, packs smaller than a soda can, reflects 90% of body heat and is sealed against wind, rain and snow. It is a highly visible orange and has a tinder-cord drawstring for fire starting.
8. Extra food
Pack more than you expect to eat. For short trips, The Mountaineers suggest a one-day emergency supply of no-cook, easy-to-digest food such as nuts, dried fruit, jerky or bars. The NPS list agrees.
9. Extra water
Water needs vary with heat, effort and altitude, so use these figures as a starting point, not a rule:
- The Mountaineers say 1.5 to 3 quarts per day (about the same in liters) is enough for most people, and that in hot weather or at altitude even 6 quarts may fall short.
- Saguaro National Park advises about 1 quart per hour of hiking in summer, at least 2 quarts per day in winter, and turning back once half your water is gone.
- Yosemite suggests a minimum of 1 quart every 2 hours.
If your route passes streams or lakes, carry a way to treat water. The Sawyer Squeeze is a light filter for day use. Sawyer lists the filter itself at 3 oz, with 0.1-micron absolute filtration that removes bacteria, protozoa and microplastics. The kit includes two collapsible pouches and a cleaning plunger, and the filter also threads onto standard 28 mm bottles. Sawyer does not claim it removes viruses, so in places where that is a concern, ask the land manager what treatment they recommend.
10. Extra clothes
Bring the layer you would need to survive a night out in the worst realistic weather for that trip: an insulating jacket, a hat and gloves, and a rain shell. The Mountaineers point out that a warm hat gives more warmth for its weight than any other piece of clothing. A spare pair of socks also helps after a creek crossing.

Extras by season and conditions
- Heat: more water than the base list, electrolyte drinks or salty snacks (Saguaro National Park recommends replacing sodium), a sun hoodie and an early start.
- Cold: insulated jacket, warm hat, gloves and a thermos. Days are short, so the headlamp matters more.
- Rain: rain jacket and pants, a pack liner or trash bag to keep your extra layers dry, and spare socks.
- Bugs: insect repellent, kept in your first-aid kit (a Mountaineers suggestion).
- Desert or exposed terrain: White Sands National Park asks for at least one gallon (about 4 liters) of water per person per day and recommends being off the trail by sunset.
Women-specific items
Peeing on the trail. A female urination device lets you pee standing up, which helps on exposed ridges, in a harness or on a busy trail. Pair it with a reusable pee cloth so you do not need to carry used toilet paper.
Period supplies. Pack what you use at home, plus a spare, and an opaque zip bag for used products. Many land managers require you to pack them out. Guadalupe Mountains National Park, for example, says toilet paper and all menstrual products must be carried out as trash, regardless of the length of the hike. Check the rules for the park you are visiting.
Footwear
Shoes are not on the list, but they decide how the day goes. Wear footwear suited to the terrain and broken in before a long hike. For new boots, see our guide to the best hiking boots for women. Pack blister supplies either way.
FAQ
Do I really need all Ten Essentials for a short hike? The Mountaineers say not every item is needed on every trip, and that the list should be tailored to weather, remoteness and route. The first seven items are compact and change little, so many hikers keep them in one bag that lives in the daypack.
How much water should I bring on a day hike? It depends on heat and effort. The Mountaineers give 1.5 to 3 quarts per day for most people, and NPS desert parks such as Saguaro advise about 1 quart per hour of summer hiking. Turn back when half your water is gone.
What should I tell someone before I go? Where you are going, which trail, and when you plan to be back. The NPS recommends leaving this plan with someone who is not hiking with you and can call for help if you do not return on time.
Summary
Pack the Ten Essentials every time, scaled to the trip: navigation, a headlamp, sun protection, a first-aid kit, a knife, fire, an emergency bivy, and extra food, water and clothes. Add a water filter if your route has water sources, pack your personal items, and leave your plan with someone at home.
