Peña Adobe Regional Park

A Step Back in Time

Tucked just off Interstate 80 in Vacaville, California, Peña Adobe Regional Park spreads across 470 acres of natural beauty with a fascinating historical twist. At its heart stands the Peña Adobe home - the oldest structure in Solano County, built over 160 years ago. This California Landmark (#534) dates back to the 1840s and offers a genuine glimpse into early California settlement.

If you're a history buff, drop by the Mowers-Goheen Museum on the first Saturday of any month for guided tours of the Adobe. Recently added QR codes throughout the historic area make self-guided explorations more engaging too.

Nature's Canvas

The park unfolds as a patchwork of rolling hills, oak woodlands, and open grasslands that change with the seasons. Spring brings lush green hillsides, while summer delivers warmer temperatures with patches of shade to seek out along certain trails.

A network of multi-use trails crisscrosses the landscape, catering to hikers, bikers, and horseback riders alike. You'll find everything from easy lakeside strolls to more challenging uphill routes that reward your effort with panoramic vistas of the surrounding countryside. Don't be surprised if you encounter grazing cattle on the hillside paths - they're part of the authentic landscape here.

Plant enthusiasts will appreciate the thoughtfully designed native plant garden showcasing local flora in its natural habitat.

Water Wonders

Lagoon Lake forms the 100-acre heart of the park, offering a tranquil setting for non-motorized boating and fishing. The lake area has become a hotspot for picnicking and wildlife observation - especially for bird watchers who enjoy spotting the numerous ducks and geese that call this place home.

A flat, accessible path circles the lagoon, providing an easier alternative to the hillside trails. Informational signs along the way help you understand how this beautiful area developed over time.

Recreation for Everyone

What makes Peña Adobe truly special is its diverse recreational offerings. Archery enthusiasts can practice their aim at a dedicated archery range, while disc golf players can tackle a challenging 27-hole course that winds through the terrain.

Dog owners will appreciate the expansive 30,000-square-foot dog park where four-legged friends can run free. For the tech-minded visitor, the park features both a RC drone runway and a race track for RC buggies tucked away in the farthest corner near the rear gate.

Planning a gathering? Multiple picnic areas dot the landscape, including a large covered gazebo equipped with barbecue pits for group events. You'll come across clean restrooms throughout the park and drinking fountains designed for both human and canine visitors.

The wide, open grassy areas invite impromptu games of frisbee or sports. While there's no playground equipment, the generous space means families can bring their own games and recreational gear.

Plan Your Visit

The park welcomes visitors year-round from 7:30AM to 7:30PM (closing earlier at 5:30PM during winter months or 30 minutes after sunset). There's a $5 parking fee, payable at kiosks located at the entrance areas.

Yes, you'll hear some background noise from nearby Interstate 80, but it quickly fades into the background as you immerse yourself in this peaceful outdoor retreat. Early risers are rewarded with particularly beautiful sunrise views, making this an excellent spot for tranquil morning exercise.
