Rockville Hills Regional Park

Natural Landscape

Nestled in Fairfield, California, Rockville Hills Regional Park spans a generous 633 acres of pure natural splendor. This location features a diverse landscape where grasslands meet oak woodlands, creating a dense mixed broadleaf forest with beautiful blue oak woodland sections throughout.

The varied terrain acts as a sanctuary for abundant wildlife that thrives here. In springtime, the grasslands fill with vibrant wildflowers that dot the landscape with their colors. If you're hoping to catch this natural display at its finest, March offers peak wildflower viewing when the park literally bursts with seasonal blooms.

Geological Features

As you explore, you'll notice the park's distinctive rolling hills and rugged rock formations that tell silent stories of the area's geological past. These time-weathered formations are scattered across the grounds. The fascinating volcanic geology adds an extra layer of intrigue for anyone with even a passing interest in natural history.

Hike up to the elevated areas and you'll be rewarded with breathtaking panoramic views stretching across the surrounding valley. On clear days, you can see Mount Diablo, Elkhorn Peak, the Twin Sisters, and even across the Carinez Straight. The lookout points also provide views of Green Valley and the Delta region.

Recreational Opportunities

With over 30 miles of tracks and trails winding through the property, there are options for various outdoor activities. Whether you're a casual hiker or a dedicated mountain biker, the trails accommodate various skill levels. Beginners can stick to gentler paths, while those seeking a challenge can tackle the technical sections that experienced riders love. The interconnected loop system lets you customize your adventure and explore different corners of the park at your own pace.

The park features the All People's Trail, a thoughtfully designed half-mile accessible path that meets outdoor accessibility standards. Unlike many accessible trails, this one doesn't just go out and back - it offers a satisfying loop with destination views. The smooth surface works well with different mobility aids, keeps grades at 8.3% or less, and provides frequent benches for rest stops.

Water features add to the park's charm, with a serene lake and a small pond where fishing is permitted. These quiet waters not only enhance the scenery but also attract diverse waterfowl, frogs, turtles, and other wildlife that might peek out during your visit.

Facilities and Amenities

Need a breather? You'll find several picnic tables dotted within the park, mainly near the parking lot, pond, and lake areas. These spots provide perfect perches to rest and soak in the views while enjoying a packed lunch.

Restrooms (vault toilets) are located about a half-mile uphill from the parking lot, between the pond and camping area. If you're cycling, you'll appreciate the handy bike repair station available for those unexpected adjustments.

You can find potable water in the picnic area, but it's wise to bring enough water for longer explorations, especially on warmer days when you'll need to stay hydrated.

Park Management

The park welcomes visitors year-round from 6:15AM to 8PM, letting you experience its natural beauty across all seasons. There's an entrance fee of $5 per person, with an additional $1 for four-legged friends.

At certain times of the year, you might notice livestock grazing across the park. This isn't just for show - it's a practical approach to fire control and vegetation management that helps maintain the park's ecological balance and natural character.

While dogs are welcome to join your adventure, they need to stay on leash to protect both the wildlife and the grazing livestock. One practical benefit: the sandy, rocky trails here drain quite well, making this park a solid choice for hiking and mountain biking even after rain when other trails might be too muddy to enjoy.
