Whether you have kids or not, the Cavalcada dels Reis is a must in Barcelona. The procession of the three kings, accompanied by their many dancers and acrobats, takes place on January 5th and is a spectacular display of colour and music. This is the most anticipated day of the year for the young (and the young at heart), and the festivities commence at 4.30pm when the Three Wise Men arrive by ship to Port Vell for an official welcome. The parade then crosses the city, along Via Laietana, past Plaça Catalunya, continuing on to Avinguda de Reina Maria Cristina, near Plaça Espanya. Melchior, Gaspar and Balthazar come bearing gifts to the crowds lining the streets, so don’t forget to take a bag to collect the sweets!
