What to Bring
Your package depends on the tours that your are going to do. In general, you need a basic outfit to hike, like hiking boots, trekking pants and thermoshirts. The sun is very strong, this is why sun cream and sun glasses are absolutely necessary. Also a sun hat that protects from sunstroke, is recommendable. As you have often the possibility to go swimming, like in the Colca Canyon, you should bring your swim clothes. The higher you climb, the lower is the temperature, therefore we recommend a warm hat, gloves and fleece. Chocolate is a good help in order to prevent mountain sickness. And do not forget your torch light, a headlight is the most suitable. Your first-aid-kit is also very important. Plastic bags are always useful.
If you do not have these items and do not want to buy them, you have the possibility to rent them here in Arequipa.
