South San Diego Bay Unit
Currently, a wonderful boardwalk complete with artistic and interpretive elements, called the "Bayside Birding and Walking Trail" is being designed. This 0.4 mile trail will extend along the Southern end of the Bayshore Bikeway, from 7th Street to 10th Street in Imperial Beach. It will be wheelchair accessible, and is expected to be completed by 2014. Stay tuned!
