Dogs-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.

This loop is a bit longer than 5 miles. It doesn't have a lot of coverage so bring lots of water and wear plenty of sunscreen because there's little to no shade. Good amount of hills even though it says "moderate". This is a good challenging trail of you are running it!

In this hike we combined the Lime Ridge South and North Loop into a longer loop. We started from the Lime Ridge South staging area at the Boundary Oak Golf Course; hiked up to the Paraiso Trail, crossed the Ygnacio Valley Road using the underpass, continued onto the Lime Ridge Trail. We then followed the Cottonwood Trail, Ygnacia Canyon Trail and Manzanita Trail. We finally took the Ohlone Trail back to the staging area. Total distance was 6 miles with 1,312 feet of elevation. I would rate it moderate. It was a beautiful hike with blooming of the spring wildflowers.

Nice quick loop, great for hill repeats. Cattle movement can close routes though so it wouldn't be ideal for timed runs.

Decent trails. Went up Manzanita to the peak which makes it shorter but more difficult. Path was washed out sandstone but it was a nice change of pace. Broken glass by the bench at the top which was upsetting. Nice little loop overall.

We had a pleasant hike at Lime Ridge Open Space on this New Year's day. This loop had a mix of fire roads and single-track trails with a total ascent of 1,350 feet over 5.8  miles. 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. We had great views of the surrounding cities and countryside.
