Sunol Regional Wilderness covers 6,859 acres of rolling hills and grassland in Alameda County, and it’s a genuinely good spot if you want serious hiking without the crowds. The landscape tells its own story — you’ll see ancient bedrock mortars scattered through the park where Native Americans ground acorns, and the land itself spent most of the last hundred years as working ranch country before becoming a regional park. That history shows in the way the terrain feels lived-in rather than manufactured.

The main draw is the trail system. Dogs are allowed on many of the trails but need to stay leashed, which is straightforward enough. The Indian Joe Nature Trail is a solid self-guided option if you want to move at your own pace without a group. You get decent views of the surrounding ridges, and your dog will have plenty of new ground to cover. The park works for everything from a quick afternoon hike to a longer exploration depending on which trails you string together.

If you’re planning to camp, bring more water than you think you’ll need. The park doesn’t have drinking water stations, so you’re responsible for carrying what you need. That’s worth planning around, especially on warmer days when you and your dog will both go through water faster.

The Old Green Barn Visitor Center has information about naturalist-led activities and guided hikes if you want a more structured experience. They sometimes run programs focused on the area’s ecology and history, which can be worthwhile if you’re interested in understanding what you’re actually looking at while you’re out there.

Equestrian trails are available too, so you might encounter horses alongside the hiking trails. The park’s website has current information on hours, parking, and any fire season restrictions that might affect access. Since regulations can change seasonally, it’s worth checking before you go, particularly if you’re planning a longer visit.
