If you have more time, you can visit other historic churches like the Cathedral di San Lorenzo or take a day trip to the Cinque Terre National Park. If you have less time, you can skip the Chiesa del Gesù and Piazza de Ferrari and head straight to the Mercato Orientale for some shopping and lunch. Don't hesitate to try some lesser-known local specialties like farinata, and don't forget to bring some suitable clothing and comfortable shoes for walking around the city.
