Festa do Peao de Barretos in Barretos
Since 1956, Barretos has hosted one of the world's largest rodeo and country music events, filling the purpose-built Parque do Peao arena for eleven days each August with bull riding competitions by day and major sertanejo concerts by night. Attendance across the run regularly reaches into the hundreds of thousands, overwhelming a city of roughly 100,000 residents and turning much of the local economy over to the festival.
Barretos built a rodeo in 1956 that grew into one of the largest country music and bull-riding events on the planet, filling a purpose-made arena in inland Sao Paulo state for eleven days each August.
