Before we can head down the trail we need to pack the equipment and supplies we will need for the hike. Whenever I hike the trails, even if I’m only intending to go a short distance, I always bring the ten essentials. Someone much smarter than me once said "The only constant in life is change." And at the Grand Canyon plans can change quickly due to the weather, illness, injury or fatigue. If you plan for a hike to take longer than you expect, you will be better prepared if things don’t go according to plan.
