What to bring to Peru / Bolivia

On top of the expected stuff, here's something that you need specifically for a trip like ours

• Altitude sickness pills - this is number 1! We brought them just in case (Diamox), but ended up taking them almost every day between Cusco and La Paz. You can try to do without, but be prepared to lose a few days just because you can't take another step. Coca tea is another thing that helps, but its effects are only mild in comparison with Diamox.
  
• Good hiking shoes - there's a lot of mountain hiking, and if you already got the altitude pills, you can begin walking up & down the Inca stairs without running out of breath too much. Invest in good ones, and you'll be a happy camper
  
• Patience - if you're used to efficiency of the western world, take it easy, because not everything is on time, and again, because of altitude, you might wanna take it easier than usual
• A Spanish phrasebook. I recommend Lonely Planet's
• Sun screen lotion & sun glasses - the sun in the mountains during the day can be severe, so watch out
• Comfy pants with a lot of pockets
  
• Money belt
