Come join us for a guided walk at Rancho San Andres Castro Adobe State Historic Park in Watsonville on Saturday, May 7, from 11 a.m. to 4 p.m.

Accompanied by State Parks interpreters and docents, you will stroll back in time to the Mexican Rancho period of the mid-1800s. That’s when the two-story Castro Adobe hacienda was built on the 9,000-acre rancho granted to Jose Juaquin Castro and became one of the social centers of the Central California Coast. See displays and hear of the Vaquero culture and skills. Learn about the cattle, horses and sheep that ranged wild on the mostly unfenced grasslands of Rancho San Andres. Experience the Fandango room where music and dance were enjoyed frequently. Visit one of the last remaining indoor cocinas in California and hear about the bear and bull fights.

Reservations are required for each individual attending this event. Masks are required on all tours, regardless of vaccination status.

Located in Larkin Valley near Watsonville, the two-story Castro Adobe is one of the finest examples of a rancho hacienda in the Monterey Bay area. Friends is leading a multi-year restoration effort to preserve and interpret the Castro and is partnering with CA State Parks to open the adobe as a State Historic Park.

The Rancho San Andrés Castro Adobe is one of the grandest of all adobe buildings representing the Mexican Rancho Period of California history (1821-1848). It was built between 1848-1850 by Juan Jose Castro, son of Jose Joaquin Castro, who was an original Juan Bautista de Anza expedition member. Later, Danish-born Hans Hansen purchased the Castro Adobe. Hansen completed many alterations to the building. Subsequent owners made changes as well, each acting as stewards of the historic adobe, including noted adobe conservationist Edna Kimbro and her husband Joe, who purchased the adobe in 1988.

In 1989, the Loma Prieta Earthquake severely damaged the building, rendering it uninhabitable. The cocina north wall and the south wall of the main house were damaged and in need of reconstruction. The Kimbro’s advocacy for restoration of the building resulted in the sale of the property to California State Parks in 2002. In 2007, in partnership with State Parks, Friends of Santa Cruz State Parks managed and funded the construction of 2,500 adobe bricks used for reconstruction and subsequent seismic stabilization.

Friends undertook the restoration of the Castro Adobe in order to preserve and interpret for the public the only remaining building of the Rancho era in the Pajaro Valley.
