Byron, Census-designated place in Contra Costa County, California.

Byron is a census-designated place in Contra Costa County, California, located in a rural area with scattered homes and open land. The community maintains a residential character with local roads connecting small neighborhoods across the region.

The first post office was established in 1878, marking the beginning of organized settlement in the area. The Byron Hot Springs Resort then drew visitors to the region starting in the early 1900s.

During World War II, the local Byron Hot Springs facility served as a military interrogation center, housing both German and Japanese prisoners.

The area offers a quiet, rural setting best explored by car, with local roads connecting to nearby communities. Visitors should plan to spend time driving between points of interest in this dispersed settlement.

The Byron Hot Springs Resort, built in 1913, served a surprising second purpose during World War II as a military interrogation facility. This transformation marked a dramatic change in how the once-popular resort was used during wartime.
