Fiestas are always spectacular in Lanzarote and Graciosa is no exception! Graciosa celebrates the Saint of Del Carmen for their Fiesta in June, normally around the 16th and 17th of June.
Carnival is another big celebration and an excuse to dress up. It is held towards the end of March depending on Easter dates (March 20 - 22, 2020)
