The city reflects Spanish influence in its architecture, such as the Cathedral, the churches of San Francisco, Belén and La Recoleta, and the two-storey houses with twin-eaved roofs. To the east of the city lie the Bathrooms of the Incas, the natural hot springs which the Inca ruler was fond of. The district also features the Ventanillas de Otuzco, a complex of burial caves carved out in pre-Inca times. The province of San Pablo is home to two major archaeological complexes: Cumbemayo, a set of ceremonial altars and Inca aqueducts, and Kuntur Wasi, a ceremonial complex of several squares and platforms held up by huge stone walls.

North of the city is Granja Porcón, a dairy farm where travelers can take part in farming chores. The farm is famous for its herd of cows which are still called by name at milking time.

Carnival time in Cajamarca is among the most famous festivals in February in Peru. The townspeople are an easy-going, amiable folk, and carnival time involves entire neighborhoods and institutions until the end of the festival, when the participants symbolically bury Ño Carnavalón, the king of the carnival. The celebrations go on for around a month, but there are eight main days, when participants are often doused with water.
