The flamenco outfit was originally worn by Spanish Gypsies (Roma people), but is now generally thought of as typically Andalusian and is particularly associated with Andalusian festivals such as the Seville Fair (Feria de Abril). The outfit originated in the late 19th and early 20th centuries when women vendors dressed in modest calico gowns adorned with ruffles came to the fairs along with livestock traders. In time, women of the propertied classes copied these outfits worn originally be rural workers.

There are three main, traditional routes, and most hermandades, wherever they are arriving from, eventually join one of these. These depart from Triana (Sevilla, to the north-east), Sanlucar de Barrameda (south), and Huelva (west). People also travel in big trailers pulled by tractors, ideally with shade as it can get very hot, as well as lots of food and drink. The rocieros sit on benches along the sides of the trailers, including many children who go on the pilgrimage every year. The more practical and comfortable, though less attractive, option is a big white caravan, with the same curved roof as the traditional models, complete with air-con and running water. This is pulled by a 4x4, as the route takes rocieros through the Doñana park, including several river crossings, so a tough vehicle is essential.
