The Iron Horse Trail spans over 30 miles and connects Pleasanton, CA to Concord. Park your car at the Dublin Bart Station and hop on the trail of flat, paved pathways surrounded by trees and foliage. Once you reach Danville, park your bike at their local bike parking station, which is within walking distance of several boutiques and restaurants. Visit the Museum of San Ramon for more information about the trail, which used to be a railroad!
