"If you could see their faces when they see Santa," said police Lt. Paul Williams. "We never have problems getting volunteers."
The annual tradition began more than 30 years ago, he said, and goes on for three nights.
Police officials along with volunteers from the San Bernardino County Sheriff's Department and city Code Enforcement, Parking Enforcement and Animal Control and from American Medical Response took the the streets for the past two nights and will again tonight.
This year, the parade kicked off Tuesday night through the northeastern portion of the city, stopping at the Perris Hill Senior Center, Serrano Middle School and a Target store.
"We have (300) to 400 people sometimes waiting for us in the parking lots," Williams said.
Wednesday night's parade began at 5 p.m. at the San Bernardino Police Department on D Street and made stops at Ramona Elementary School, the Lytle Creek Recreation Center and Norton Elementary school, among other locations.
Tonight Santa will start his journey at San Bernardino Fire Station No.232 at 6055 Palm Avenue, then he will continue his journey through the northwestern area of the city, making stops at Shandin Hills Middle School and Marshall Elementary, Northpark Elementary and Palm Elementary schools.
