Make sure you spend a at least 2 to 3 days at altitude before attempting the Inca Trail. The more time you can spend at altitude the more your body will have adjusted to it.
Coca – Leaves, Tea, Candy
Most of the locals will all consume coca. You can chew Leaves, Drink Tea or eat Candy. The benefits of this are a Boost in Energy, Suppression of Hunger and alleviating the effects of altitude.
Our porters woke us every morning with a cup of coca tea, and we had bought a few bags of coca candy and lolly-pops to take on the trail… don’t get me wrong, it does not taste great but it does help.
Speak to your doctor before you go, as you will be above 4000m they may give you a prescription for altitude sickness tablets.
