Rock al Parque or Rock at the Park is an open air rock music festival. Recurring annually, it gathers over 320,000 music fans who can enjoy over 60 band performances for free during three days a year. The series have been so successful during its 15 years of operation that the city has replicated the initiative for other music genres, resulting in other recent festivals like Salsa at the Park, Hip Hop at the Park, Ballet at the Park, Opera at the Park, and Jazz at the Park.
