Your Fourth District

San Bernardino County’s 2.2 million residents are divided into five geographically distinct districts. The Fourth District of San Bernardino County is a diverse and vibrant home to 477,000 residents. There are five robust cities within the district which boast many unique destinations and amenities. Residents and visitors alike can take advantage of the close proximity to Ontario Airport and plan a visit to Ontario Mills Mall or Toyota Arena in Ontario, spend a lazy afternoon at Prado Park or the Planes of Fame Museum at Chino Airport in Chino, take a hike at Chino Hills State Park or tour the remarkable BAPS Indian Temple complex in Chino Hills. Catch a concert at The Canyon Theater at Montclair Place in Montclair or a play at The Grove Theatre in the beautiful historical downtown Upland. Although smallest in physical size when compared to the other four county districts, the Fourth District has so much to offer our residents and visitors alike.
