As I was driving back into Almerimar yesterday I spotted a poster for the 2017 fireworks displays in El Ejido. I think it said they are starting on the night of 29 June 2017 and will take place each night for a few nights.
The video above is lifted from youtube. It is of one of the fireworks shows last year.
I will publish more details here about the dates and times of the shows once I have the information.
