Ancient Mayan sites are scattered over rather a wide territory, covering parts of what are today Mexico, Guatemala, Belize and Honduras. But if you want things narrowed down to just former cities with pyramids, the internet obliges – in competing ways; for example:
On our three-day car-based excursion around Yucatan, besides Coba, we also made a visit to the famous Chichen Itza, including its centerpiece, El Castillo, aka the Temple of Kukulcan. Have a read of what that link takes you to – especially about the steps and the platform (=365), and about the ‘snake’ that slithers down the pyramid on an equinox.
The Maya were masters of astronomy and light-and-shade-architectural effects, but there was no equinox while we were there, so no snake. Still, this was just as well since the serpent attracts huge crowds, which I can’t be doing with.
We were there early morning; accordingly – very quiet.
