San Francisco's Carnaval transforms the Mission District into a vibrant celebration of Latin, Caribbean, and Afro-Diasporic culture each May. This free two-day festival spans 17 blocks with five stages, 50 local performers, and 400 vendors, capped by a Grand Parade featuring 60 contingents and over 3,000 artists. It's one of the city's most colorful and energetic annual events, drawing crowds to experience live music, dance, food, and community spirit in the heart of the Mission.
