For day hikes and overnight trips, don't leave the trailhead without them! The most important thing to carry with you is your good judgement, but all packs should contain:
1. MAP/COMPASS: Use them to know where you are and where you are going. Be sure to tell someone at home of your plans.
2. WATER: Bring at least one quart per person or bring awater filter.
3. FIRST AID KIT: You may need to come to your own rescue, or help someone else. Be prepared!
4. FOOD: Carry plenty to snack on all day. Reduce packaging to eliminate trash.
5. SUNSCREEN/SUNGLASSES: Protect yourself - the sun shines brighter up here.
6. STORM GEAR: A beautiful sunny morning can turn into a cold rainy afternoon. Plan ahead!
7. MATCHES: An emergency campfire might make an unplanned night outside more bearable.
8. KNIFE: Handy for all kinds of purposes, especially the type with extra tools.
9. FLASHLIGHT: A necessity when the day is short and the trail is long.
10. GARBAGE BAG: For your trash and for trash you find along the way.
For overnight trips bring the ten essentials and the items below.
TENT: It can rain at night in theSierra.
BEAR RESISTANT FOOD STORAGE CANISTER: The best way to make sure you, not the wildlife, eat your food.
