Drink plenty of WATER. Even when you don't think you're thirsty,drink. Hydration will help fend off altitude sickness (headaches and nausea). Walking sticks....they will help take the weight of a full pack off of your knees. Have fun, take pictures. When you come home, make notes on what worked and what didn't. You will think of 50 things that you will need for next year.
