Make sure to bring sun screen
Travel as light as possible. Laundry is still quite cheap at most hotels and hosterias, so take advantage of that. If you have any plans of doing hiking here make sure you bring good boots.You will definitely want to bring a good jacket, particularly as you are going into higher elevations, it gets cold in a hurry! Make absolutely sure that you bring sun screen, particularly if you are planning to go out hiking or anything like that. Though the temperature is cool and mild, the sun at this altitude is very strong. Go protected.Check with your doctor about any medications for altitude sickness.
