Taking Care of Yourself

Balance Food and Water

Do not force fluids. Drink water when thirsty, and stop when you are quenched. Over-hydration may lead to a life-threatening salt-balance disorder called hyponatremia.

Restore Your Energy

Eat double your normal intake of carbohydrates and salty foods. Calories play an important role in regulating body temperature, and hiking suppresses your appetite.

Caring for Your Body

Take plenty of breaks and enjoy the view while resting. Resting allows time for proper digestion. If you are hot, cool off by getting wet in creeks and water stations. If you are cold, put on layers and eat food.

If you start to feel nauseated, dizzy, or exhausted, stop and rest. Slowly begin to drink and eat until you feel better. This can take an hour or longer.

Environmental Hazards

Rock Fall

Rock falls are common during or after rain, or during freeze/thaw events. Falls can occur without warning. If you hear or observe rock fall, move quickly away from the area. Do not stop if loose rocks are on the trail.

Flash Floods

Flash floods can occur without warning. Know the weather upstream. If you hear a roaring noise move to higher ground immediately. Face upstream when in or near a creek and have a fast exit plan.

Storms, Wind, and Ice

High winds, storms, and ice can knock down branches. Listen for cracking sounds and move away from the tree. Be aware of trees in campsites. Sudden limb drops can occur even on windless days.

Cold Temperatures

If you are cold, put on layers and eat food. Hypothermia can set in at relatively high temperatures. Make sure to wear weather appropriate clothing at all times of year.

In Summer, Avoid the Heat of the Day

Avoid hiking between the hours of 10:00 AM and 4:00 PM.
