The original adobe structure was built in 1842 by Juan Felipe Peña and Manuel Cabeza Vaca, the area's first non-native settlers.
The park contains an exhibit of a reconstructed Indian hut, honoring the original Patwin inhabitants of the valley.
The site is part of the original Rancho Los Putos land grant, which spanned over 44,000 acres.
The interior of the Adobe is periodically furnished with period-accurate 19th-century artifacts maintained by the Vacaville Heritage Council.
The park provides habitat for local wildlife, including golden eagles and red-tailed hawks often sighted on the adjacent ridge lines.
Peña Adobe Regional Park serves as a historical gateway to Vacaville, featuring one of the oldest standing structures in Solano County, the 1842 Peña Adobe. The site functions as a multi-use outdoor recreation area integrated with the larger 470-acre Lagoon Valley Park. Visitors can access the restored adobe home, which is managed as a small museum to reflect early California pioneer life. The park grounds provide significant space for hiking, picnicking, and dog exercise within a scenic valley setting. It acts as a preservation site for the history of the Vaca and Peña families who settled the region following a Mexican land grant. The landscape is characterized by rolling hills and open fields typical of Northern California's inland coastal range.
