Carnival of Platja d'Aro Activity · Castell-Platja d'Aro, Baix Empordà, Girona Image of Castell-Platja d'Aro, not of the place itself. One of the most crowded carnivals on the Costa Brava, with more than 50 years of history and a large parade of floats and costumed groups. Revived in 1978 and inspired by central European models, it is today a leading carnival event in the comarca. Febrero Photo: Chupa cabras (CC BY 3.0) What to see and do in Castell-Platja d'Aro
