There will be many parades during Carnaval in different sectors of the city. You’ll see recurrent characters that are super traditional, like cumbiamberos, negritas puloy, marimondas, and monocucos just to name a few. For an in depth explanation of this, check out Pacho’s Intro to Carnaval.
You will also see original costumes that people make up based on the major events of the past year. I remember for example seeing different representations of the Chikunguña mosquito that caused so many fevers and pains last year. Some characters are fantasy and others are based on real life. I’m sure we’ll see some Donald Trumps running around this year.
