The official events are starting to trickle in. The Museum of Popular Arts has posted their annual event.
The event is the "Alebrijes Parade". It starts in the Zocalo at 12 noon on 18 October and ending in the Chapultepec Park.
The parade includes all handmade floats from villages around Mexico. They will end up stationed on Reforma and the surrounding areas after the parade.
Side note: Rumors are still going around that the mega parade will take place on November 1st from Chapultepec Park going to the Zocalo. I won't post the official notice until it is confirmed, because every year it's wrong. If you don't want to wait to book a room you can take a chance and book one for 11/1/2025. Unfortunately, in Mexico everything is done almost last minute.
