Lime Ridge is located on the eastern edge of Walnut Creek on a dominant ridge leading to Mount Diablo. It contains some of the last remaining chaparral in Walnut Creek and a rich diversity of plant and animal life. Lime Ridge gets its name from the limestone in the area that was quarried by the Cowell Portland Cement Company. There are many hiking, biking, and wildlife viewing opportunities through multiple plant communities and quarries. Portions of Lime Ridge are within the City of Concord and managed by The city of Walnut Creek.

 

Dogs?
Yes, although leash rules vary depending on what section you are in and rangers recommend dogs remain on leash at all times.

In the North Lime Ridge area, north of Ygnacio, dogs must be under positive voice and sight command or leashed at all times. Since cattle graze in this area, dogs chasing cattle can be a serious issue. Lately, there have been some negative dog vs. coyote encounters when dogs stray close to dens as well.

No dogs are allowed at any time in the center section of Lime Ridge south of Ygnacio. This is the Lime Ridge Wildlife Preserve area. South of the Preserve, dogs are allowed once again but on leash only.
