The New Mexico History Museum presents the history of the state of New Mexico in six sections—five following the state from the days of Spanish colonization through stages up the present day, and the sixth focusing on modern New Mexicans' perceptions of their state.

The museum offers exhibits, research library access, and recreational and educational events.

The Sanchez Adobe was constructed between 1842 and 1846 by Francisco Sanchez, owner of Rancho San Pedro and one-time alcalde of San Francisco. Sanchez was a leader of Mexican California who led volunteers against United States forces at the Battle of Santa Clara. Today, the site shows the different periods of local history. Visitors can take a walk on the grounds and see native plants—the Ohlone village of Pruristac was located on the site. They can view the location of the original Spanish farm buildings; explore the Sanchez family's adobe home; and discover what items were uncovered during archaeological digs, including items from the adobe's time as a hotel and speakeasy.

The site offers exhibits and educational programs.

Visitors to this park can step into the past on the "Monterey Walking Path of History" and view the site where Spanish explorers first landed in Monterey in 1602; see one of the nation's last remaining whalebone sidewalks; and walk the same streets that author Robert Louis Stevenson walked in 1879 as they explore this two-mile path and discover some of California's most historic homes, buildings, and gardens along the way. Monterey served as California's capital under Spanish, Mexican, and U.S. military rule. The U.S. flag was first officially raised in California here on July 7, 1846, bringing 600,000 square miles of land to the United States. Ten buildings, including the Custom House, the oldest government building in California, and several residences (now house museums with guided tours), are all part of the Path of History.

The park offers exhibits, tours, educational programs, occasional living history events, and occasional other educational and recreational events.

Petaluma Adobe State Historic Park was the main residence of Rancho Petaluma, the agricultural empire that made General Mariano Guadalupe Vallejo one of the most powerful men in the Mexican Province of California from 1834 to 1846. Vallejo ran his cattle, hide, and tallow business; raised sheep; bred horses; and grew numerous crops. The adobe contains authentic furniture and exhibits depicting early rancho life. The huge adobe building, the largest private rancho in California between 1834 and 1846, was the center of activity on one of the most prosperous private estates established during the Mexican period.

The park offers exhibits; tours; and occasional recreational and educational events, including living history events.

The historic town of Sonoma is located in the heart of the beautiful wine country between Napa and Santa Rosa off Highway 12. Situated around a central plaza (the largest of its kind in California) filled with shops and restaurants, the city is home to Sonoma State Historic Park—site of the northernmost Franciscan Mission in California and birthplace of the California State Bear Flag. Unlike most parks with a plot of land and geographical boundaries, Sonoma State Historic Park is a series of historic attractions in several locations within the community. The park is comprised of six sites: the Mission San Francisco Solano; the Blue Wing Inn; the Sonoma Barracks; and the Toscano Hotel, as well as La Casa Grande and Lachryma Montis, the homes of General Mariano Guadalupe Vallejo, Military Commander and Director of Colonization of the Northern Frontier.

The park offers exhibits and tours.

The Moraga Historical Society seeks to preserve and share the history of Rancho Laguna de los Palos Colorados—now Moraga, Orinda, and Lafayette, CA. The rancho, created in 1841, was a 13,316-acre land grant awarded to Joaquin Moraga and Juan Bernal by the Mexican government. To achieve their goal, the society operates a history center with artifacts and archival materials.

The society offers exhibits and archival access.

This park is part of a nationally recognized historic landmark and can be found adjacent to the extant portion of one of California's 21 Spanish-era mission church sites. The park and its Plaza represent what was once the "town square" of the largest town in central California and a vital crossroad for travel between northern and southern California. In the park visitors can gain an appreciation of California peoples, from Native Americans, through the Spanish and Mexican cultural influences, right up to the American period in the late 19th century. The park site includes several structures built in the 1800s. These include the four main historic structures of the Plaza Hotel, the Zanetta House/Plaza Hall as well as Plaza Stables, and the newly reopened Castro-Breen Adobe with colorful and informative exhibits to help create a learning environment for people of all ages. Many of the interiors are arranged as furnished vignettes. The park also features a blacksmith shop, the historic jail, and an early American settler's cabin.
