Nice hike with great views of the Tri Valley. I went on an overcast day because you will be exposed for most of the hike. There is a small section that goes through the woods and along a block of town homes about half-way through. I look forward to going back and hiking up Calaveras Ridge Trail.
This loop trail is ideal if you want a relatively quick hike in West Dublin. From the back of the California Highlands condo complex, the loop takes about 45 minutes to complete. At the top of the hill, you are rewarded with views overlooking the Tri-Valley. The trail is not super difficult, but there are definitely up hill portions to get your heart rate up. I have seen Turkeys, Coyotes, and all sorts of birds and ground critters along the hillsides.
