For a day hike of a few hours to a full day. Most search-and-rescue
calls start as day hikes — people carry less because they plan to be
back by dinner. Pack as if you might spend the night out; that's the
whole point of the Ten Essentials.

## Planning (days before)

- [ ] Pick a route matched to the slowest person's fitness
  Rough pace math: 2 mph on trail, plus one hour per 1,000 feet of
  elevation gain. Work backward from sunset.
- [ ] Check the forecast for the trailhead and the summit, not your city `{essential}`
  Mountain weather can differ by 20°F+ and turn in an hour. Check again
  the morning of, and pick a bail-out point in advance.
- [ ] Check trail conditions, closures, and permit requirements
  Land manager websites and recent trip reports catch washouts,
  snowfields, and fire closures that maps don't.
- [ ] Download offline maps and print or photograph a paper backup
  Assume no cell coverage. A phone map with a dead battery is a brick.
- [ ] Tell someone your route, trailhead, and return time `{essential}`
  Name the trail, where you'll park, and when to call for help if they
  haven't heard from you. Then don't change plans without telling them.

## Pack the Ten Essentials

- [ ] Navigation: map, compass, and a charged phone or GPS `{essential}`
  Carry the map and compass even with GPS — and know how to use them
  together. Bring a battery pack for the phone.
- [ ] Headlamp with spare batteries `{essential}`
  A phone flashlight doesn't count: it kills the battery you need for
  navigation and emergencies. This is the item benighted hikers miss most.
- [ ] Sun protection: sunscreen, sunglasses, sun hat
  UV rises about 10% per 1,000 feet of elevation, and snow reflects it
  back up at you.
- [ ] First aid kit, including blister care `{essential}`
  Blisters are the most common trail injury; moleskin or tape applied
  at the first hot spot saves the day. Add any personal medications.
- [ ] Knife or multi-tool
- [ ] Fire: lighter or waterproof matches, plus a fire starter
- [ ] Emergency shelter: space blanket or bivy sack `{essential}`
  Two ounces and a few dollars. This is what turns an unplanned night
  out from life-threatening to miserable.
- [ ] Extra food beyond what you plan to eat
  One extra day's worth for a day hike — things that keep: bars, nuts,
  jerky.
- [ ] Extra water, plus a filter or purification tablets `{when: water-on-route}` `{essential}`
  Baseline: half a liter per hour of moderate hiking, more in heat.
  Never drink untreated surface water, however clear it looks.
- [ ] Extra clothes: insulation layer and rain shell `{essential}`
  Enough to survive a night at the coldest plausible temperature.
  Skip cotton — wet cotton loses its insulating value and chills you.

## At the trailhead

- [ ] Recheck the weather and confirm your turnaround time
  Set a hard clock time to turn around regardless of how close the
  summit feels. Getting caught out after dark starts here.
- [ ] Leave a trip plan visible in your car only if the lot is attended
  A note on the dashboard also tells thieves how long you'll be gone;
  the person at home is your real safety net.
- [ ] Put your phone in airplane mode
  Searching for signal all day can drain the battery you'll need for
  the map or an emergency call.
- [ ] Sign the trail register `{when: register-present}`
  It's the first place searchers look.

## On the trail

- [ ] Eat and drink on a schedule, not by thirst
  A few sips and a bite every 30–45 minutes. By the time you feel
  thirsty you're already behind, and dehydration reads as fatigue.
- [ ] Note landmarks and junctions, especially looking backward
  The trail looks different in reverse. A photo at each confusing
  junction costs nothing.
- [ ] Turn around at your turnaround time `{essential}`
  The summit is optional; getting home is not. Most hiker fatalities
  involve pushing on past the plan.
- [ ] Stay put if you get lost `{essential}`
  Stop, stay warm, make yourself visible and audible. A stationary
  subject is found far faster than a moving one.

## Back home

- [ ] Check in with your contact person
  Do this first, before the shower — an overdue call can trigger a
  search.
- [ ] Check yourself for ticks `{when: tick-season}`
  Scalp, waistband, behind knees, armpits. Removal within 24 hours
  dramatically lowers Lyme risk.
- [ ] Restock the first aid kit, food, and batteries you used
  Do it now, while you remember — the kit only works if it's full at
  the next trailhead.
