The Pena Adobe/Lagoon Valley Park Trails are a nine-mile long system of loop trails near Vacaville, California, a self-proclaimed dog-friendly city. Gorgeous trails surround a lake where multiple water activities take place throughout the year.
The scenic Pena Adobe Park is 470 acres of family- and pet-friendly fun, including historical features, barbecue areas, outside activities, trails, and Lagoon Valley Lake, where you can enjoy fishing and non-motorized boating.
Fido will enjoy the 30,000 square foot fenced-in dog park, and choosing which trail to hike will be your dilemma, since there are many different trails that offer both easy and challenging hikes.
The main trail in the system is the 2.1-mile Lagoon Valley Road Loop. Much of the trail is steady, but there are quite a few steep grades to climb. The abundance of cattle in the area has engraved steep indentions in quite a few areas that are natural cow paths. Warning signs indicate the presence of mountain lions in the area, so keeping your furry pals on their leashes is not only the rule, it is also important for their safety.
The trail begins in a figure eight loop and provides decent shade. It continues through a gate to a fire road, where you will go through some switchbacks until you end up back on the single track. This takes you to the peak of the mountain for beautiful scenic views.
From the peak, you descend back through more switchbacks that take you to the fire road. A left at the fire road brings you to a relaxing picnic area where you and Fido can celebrate your victorious trek on the challenging trail. When you are ready, you can head to the water tanks that you will see on Hamburger Hill. They take you down a steep descent to the figure eight where you started, and then you can enjoy the park's amenities before you end your day.
