Each town or city has its own fiesta. They’re never at the same time, so there is pretty much guaranteed a fiesta going on somewhere in the Philippines at any given time. I believe (but I’m not 100% sure) this fiesta was the anniversary of the town. How many years old? Im not sure.
We were able to catch some boat races, dances in the street and shows in the main outdoor auditorium. The streets were full of people eating and drinking all night. It was a great vibe. Fiesta seems to be a time where everyone can really let loose and just enjoy the things you have and the people you love.
