It could be described as a backstage pass to the Diablo and San Ramon valleys.

The Iron Horse Regional Trail runs south to north in almost a straight line from the Dublin/Pleasanton BART station to Highway 4 in Pacheco.

In all, it travels slightly more than 30 miles.

It cuts through so many communities and many people walk, bike and ride on it every day. So, share your photos with us. You can upload your Iron Horse Trail photos by first logging into Danville Patch then, on this page, clicking the "Upload Photos and Videos" button under the lead image.
