The Peña Adobe Hill Trail offers a rewarding, quick escape with diverse terrain and expansive views over Lagoon Valley. You'll navigate a mix of gradual slopes and steeper single-track switchbacks, leading to a prominent viewpoint that showcases the 100-acre Lagoon Valley Lake and the surrounding parkland. It's an easy 1.8-mile (2.8 km) hike with 661 feet (201 metres) of elevation gain, typically taking around 54 minutes, making it a great option for a brisk outing.
Planning your visit is simple, as the trail is conveniently located right off Interstate 80 in Vacaville. While the overall hike is considered easy, be prepared for some challenging ascents that can get your heart pumping. For the best experience, aim to visit during the cooler fall and winter months when the landscape is lush and you might spot local wildlife.
Beyond the scenic workout, this trail is part of the larger Peña Adobe Regional Park, which is rich in history. The park is home to the Peña Adobe, built in 1842, which stands as the oldest structure in Solano County and is a California historical landmark. The area also boasts diverse flora and fauna, adding an extra layer of interest to your hike.

From the highest point of the ridge in Lagoon Valley Park there is a straight view down into what looks like a Concentration Camp: California State Prison - Solano. The male-only prison holds over 5000 inmates, double its design capacity. The adjacent California Medical Facility prison has a design capacity of 2,179 but a total institution population of over 3,000 sick inmates. The California prison construction boom between 1984 and 2005 was driven by years of increasingly tough anti-crime legislation, and began with the construction of California State Prison, Solano, which opened in August 1984 https://en.wikipedia.org/wiki/California_State_Prison,_Solano
