Didn't do much apart from some shopping and finding the Witches market which although some of the things on the stalls were odd, it was not as big or as varied I had hoped.

The Witches market is found in the center of the everyday market, it sells herbs, folk remedies of all kinds. Including ingredients used to contact many spirits that are found in the Aymara world. 
Died herbs and seeds are common parts of frogs and insects all used in rituals. The most alarming is dried Llama fetus these are buried in the foundations of new buildings as an offering to the goddess Pachamama. This is supposed to protect the workers from accidents and bring good luck. This is common if you are poor the rich are expected to sacrifice a live Llama.

Often found in the market are witch doctors or yatiri recognized by their black hats and coca leave pouches.
