The epitome of a nice backyard hike, this trail starts in Alvarado Park and loops around the adjacent Wildcat Canyon Regional Park. Wildlife abounds — cows, foxes, coyotes — as does California flora. Your dog(s) will enjoy it as much as you do. Cresting the San Pablo Ridge gives 360-degree views of rolling hills, the Golden Gate Bridge and the sprawling Bay. Tip: Water bottle refilling opportunity two miles into the hike.
