Contra Costa County
Travelers whizzing through Contra Costa County on their way to San Francisco or San Jose might know the area only for its conveniently located rapid-transit stations—and that’s a shame because this scenic and affluent slice of the Bay Area is worth visiting for the dog treats alone. Concord is a DogTrekker favorite, featuring affordable lodging, close proximity to the world-class wines of Napa and Sonoma Valleys, outdoor exploration and family and dog-friendly attractions.
