Despite concerns that the weather or politics would ruin the spectacle, the event went off without a hitch.
The site’s capacity was limited to 15,000 people out of concern for the security of Chichén Itzá’s historic monuments, as well as the spread of COVID-19.
After roughly 3 p.m. the maximum capacity had already been reached or surpassed, making access impossible.

On “normal” days at Chichén Itzá, tourists spread across the massive site. But during the spring equinox, eager visitors tend to tightly huddle in front of El Castillo to observe the astronomical spectacle.
Though the use of facemasks was compulsory, many tourists had to be reminded time and time again to wear them, while they complained about the over 100-degree heat.
Aside from INAH security, Chichén Itzá was also heavily patrolled by uniformed police officers and national guard.
As is typical in Chichén Itzá, among the crowds were large numbers of vendors selling everything from handicrafts to hats and umbrellas to help beat the heat.
The ever-growing popularity of Chichén Itzá as a tourism destination has raised concerns regarding preservation and led to several measures intended to protect its ancient monuments.
Some of these have included blocking access to climbing its structures as well as a “shrinking” of the site which renders previously open areas of the ancient city unexplorable.
However, INAH announced last year that Chichén Itzá would soon have a second entrance, enabling visitors to explore a section of the site known as Chichén Viejo or Old Chichén.
This section of the site is unlikely to open its gates before next year. But INAH has said that It will only be accessible through reservations.
