Sundays at the Spreckels Bandshell mean free reggae echoing through Golden Gate Park. Bring a blanket, pack a picnic, and settle into the grass while roots, dub, and dancehall fill the air. The crowd is a true San Francisco mix: barefoot kids dancing, longtime reggae heads nodding, and curious wanderers from nearby museums. No tickets, no gates, just sunshine and bass lines that seem to come from the earth itself.
