Chesbro Reservoir is a 2.6 mile loop trail located near Morgan Hill, CA and is good for all skill levels. The trail is primarily used for walking, mountain biking, and canoeing and is accessible from April until October.
I've lived one mile from this my whole life. It's a resevoir in the center of a set of roads among houses in the mountains. It's a beautiful place to bike and run. I wish we had more runners around here. Not a "trail," though, it's a paved road. Please don't fish here, though. It's right near Uvas, (just 8 miles down the road) which is amazing for hiking. So if you're driving, stop at Uvas, too!
