The Crockett Historical Society and Museum preserves the history of the town of Crockett as well as neighboring communities of Valona, Tormey, Vallejo Junction, and Eckley. Since 1906, the C&H Sugar Company has been a big influence on the history of the area. The museum is in the former Southern Pacific depot that the society has rented from C & H Sugar since 1981.

The museum has displays about the C & H Sugar Company, other businesses in the area, churches, the building of the Carquinez bridges, social and fraternal clubs, military service members, and the area schools. There is also a large collection of materials from the C & H Sugar Company including albums of photos. In the museum, there is a set of binders with surveys filled out by hometown WWII vets including photos.

Their archives houses photographs, maps, newspapers, and historic documents. There is a searchable database for two of Crockett newspapers, Cublet (C & H Sugar) and Crockett Signal is available at their site. At one whole wall in the office stands a bank of file cabinets with surname and subject files. Another cabinet houses photos from various schools. The map case holds maps and large posters.

The museum welcomes visitors to conduct research.
