Madrid Gay Pride is one of Europe’s most fun gay pride festivals (Madrid Orgullo) and attracts hundreds of thousands of onlookers to a parade (on the saturday) of floats that winds its way through the grand avenues of Spain’s capital city. In fact, Gay Pride Madrid could well now be Europe's largest pride parade - with warm weather and an amazingly gay-friendly atmosphere drawing in thousands of visitors from all over Europe and the world. After the Gay Pride Madrid parade, the crowd dissipates (many end up in the La Chuca district) to a number of parties and events held in and around the city.
