Late April through early August marks the Ibiza Opening Parties season, with mid-to-late May being the busiest time of the year in the clubbing capital. Line up usually features DJs from all over the world who come to turn on the island of endless dancefloors. The Spanish call it Apertura Ibiza, which literally means "Ibiza Opening." Every club tries to throw the biggest and the most stunning parties. Tickets are sold out quickly, so book in advance and don't miss the incredible Ibiza fun. See the full schedule by the link in the External Resources below.
This is when the clubbing season kicks off. The official start is considered the International Music Summit (IMS) which takes place at the end of the month between Ibiza Town and Playa d'en Bossa. However, several clubs host opening parties earlier than that. Such superclubs as Amnesia, Pacha and Sankeys are the very first to open their doors. While other big clubs such as Ushuaïa, DC10, Privilege and Hï Ibiza open later in May. So if you have your favourite club in Ibiza, make sure to check for its precise opening dates to not miss the party of your lifetime. Note that opening parties are actually held after the big opening of a club itself.
The opening parties are held across Ibiza. But the most fashionable resorts to check out are Ibiza Town, Playa den Bossa (Platja d'en Bossa), San Antonio (Sant Antoni de Portmany), and Santa Eulalia (Santa Eulària).
