Walnut Creek Wilderness Park and the Michael D. Antonovich Trail in San Dimas is a favorite place to ride among horse enthusiasts. But it's also a great place to walk with your dog.
With its year-round stream, you are guaranteed many opportunities for your and your dog to get your feet wet! The 2.5 mile trail through this 60-acre preserve meanders back and forth over the stream multiple times. For the most part, the trail is shaded so it is a cool place to hike on a hot day.
