A yellow fever vaccination is only required if you are coming from infected areas of the world or for your own protection if you are going to the Amazon Jungle. You should consult your health care provider before traveling.

You should avoid tap water. Your stomach may become upset due to the change in diet. Anti diarrhea medicine is recommended, just in case. Fish and seafood are excellent on the coast, but you should make sure they are fresh before eating them, always well cooked. Also you should peel fruits before eating them.

When traveling to altitude locations, like Cusco, Machu Picchu, Arequipa, Colca Canyon or Lake Titicaca, you should try to eat light and most important rest for a few hours before starting your activities.
