Smaller versions of the festival are held in various parts of the province, also to celebrate and honor the Santo Niño. There is also a "Sinulog sa Kabataan" performed by the youths of Cebu a week before the parade. Recently, the festival has been promoted as a tourist attraction, with a contest featuring contingents from various parts of the country. The Sinulog Contest is usually held in the Cebu City Sports Complex.

The Sinulog celebration lasts for nine days, culminating on the final day with the Sinulog Grand Parade. The day before the parade, the Fluvial Procession is held at dawn with a statue of the Santo Niño carried on a pump boat from Mandaue City to Cebu City, decked with hundreds of flowers and candles. The procession ends at the Basilica where a re-enactment of the Christianizing (that is, the acceptance of Roman Catholicism) of Cebu is performed. In the afternoon, a more solemn procession takes place along the major streets of the city, which last for hours due to large crowd participating in the event.
