In case you weren’t paying attention to your copy of “Sant Cugat Avui” that the municipality is nice enough to mail out, here’s the parade route of the “Tres Reyes Magos” for Sant Cugat on January 5th:
There are two main events: the Cavalcada de Reis, which is the parade where they throw candy and little presents for kids. The parade has a wonderfully campy feel to it and it’s quite impressive how much effort gets put into it.
The Ambaixadors Reials (on January 4th) is more like a “sit on Santa’s Lap” kind of event. There’s lots of videos on Youtube about it.
