Yes, many of the regional parks and trails in the Brentwood area are dog-friendly, but policies can vary. For example, dogs are generally permitted in the East Bay Regional Parks, which include Round Valley Regional Preserve and Black Diamond Mines Preserve, but they must be on a leash in developed areas. Always check the specific park's regulations before you go, as some sensitive wildlife areas may have restrictions.
For a family-friendly outing, the Marsh Creek Regional Trail is an excellent choice. It's a paved, multi-use path that is mostly flat, making it suitable for strollers and young children. It connects several parks and offers a pleasant walk along the creek. Many city parks in Brentwood also feature shorter, easy walking paths perfect for a family stroll.
Spring is a spectacular time to hike near Brentwood, especially in places like Mount Diablo State Park, which is famous for its vibrant wildflower displays. The weather is mild and the hills are green. Autumn also offers pleasant temperatures for hiking. Summers can be very hot and dry, so if you hike during this season, it's best to go early in the morning and carry plenty of water.
The terrain around Brentwood is characterized by open grasslands and rolling hills with little shade. It's essential to bring plenty of water, especially during warmer months.

Also, be aware of your surroundings for wildlife like snakes and grazing cattle.

It's a good practice to check the specific park's website for current fee information before your visit.
Round Valley offers a more remote, rugged experience with trails winding through open grasslands and oak-wooded hills, known for scenic vistas and wildlife.

A key difference is the panoramic view from Diablo's summit, which is unparalleled in the region.
