There is a really beautiful, cool and fat monument in Querétaro: the aqueduct. This is a whole long continuous line/wall of archways that runs through Querétaro. Really very cool.
And of course there is also a viewpoint here, which you can reach via a staircase, from where you have a really nice view of Querétaro itself as well as the aqueduct, which then slowly gets smaller on the horizon and merges with the city.
There is also a small church at the viewpoint and if you walk away from the viewpoint, you will come back to the centre of Querétaro via streets, squares and beautiful buildings.
Go or not? Yes, definitely. For me personally, the aqueduct together with the Café Diktatur in Querétaro itself was my absolute highlight 😊
