Hurling is 15-a-side, the stick is called a hurley, and the ball — a sliotar — travels fast enough that first-timers usually spend the opening minutes recalibrating their expectations. Gaelic football is closer to a hybrid of soccer and rugby, and the physicality is genuine — nobody's buying a foul. The SF Gaelic Athletic Association has been running these finals for decades, and the final-day crowd skews expat Irish with enough longtime SF regulars that the atmosphere is knowledgeable rather than touristy.

Treasure Island is a 15-minute drive from downtown; no direct BART, so plan for the 108 Muni bus from Transbay or carpool. Parking on-island is available but fills on event days — come early or rideshare to the island entrance. Food options on TI are limited; grab something in the city before you cross. Admission is typically free or low-cost for GAA finals, but confirm at the gate.

With two hours: catch the second half of the hurling final, stay for the Gaelic football throw-in, walk the island perimeter for the skyline view on your way out.
