Local fiestas called turnos are found nationwide, notably in Guanacaste and Nicoya, highlighted by rodeos, fireworks, and firecrackers (bombetas). Individual towns also celebrate their patron saint’s day: Highlights usually include a procession, benign bullfights, rodeos, dancing, and parades.
Costa Rica is a Catholic country, and its holidays (feriados) are mostly religious. Most businesses, including banks, close on official holidays. The country closes down entirely during the biggest holiday time, Easter Holy Week (semana santa), Wednesday through Sunday—a good time to see colorful religious processions. Buses don’t run on Holy Thursday or Good Friday. Banks and offices are closed. And hotels and rental cars are booked solid months in advance as everyone heads for the beach. Avoid the popular beaches during Easter week. Most Ticos now take the whole Christmas (navidad) holiday week through New Year as an unofficial holiday.
