What do you know about Lime Ridge Open Space Trail?

This athletic loop, a perfect cool-weather outing, uses the Ohlone, Manzanita, Lime Ridge, and Paraiso trails to explore the rugged, chaparral-clad hills northwest of Mt. Diablo on the border of Concord and Walnut Creek. Lime Ridge Open Space is a vaguely key-shaped parcel of land stretching from Concord south into Walnut Creek.  The open space is cut into three chunks by two bisecting roads bustling with auto traffic. Each section generally serves the directly adjacent neighborhoods, offering broad dirt trails through rolling grassland, perfect for dog walking, and daily strolls or runs. Lime Ridge hosts no facilities, and many trails are unsigned, but it would be tough to get lost in this small open space preserve. Southeast of Ygnacio Boulevard you'll find slightly steeper hills ascending through oaks and then chaparral. These hills reach toward Mount Diablo State Park, but trail access is blocked by intervening private lands.
