Park Description:
The Martinez Regional Shoreline Park is one of a dozen East Bay Regional parks. This one is located adjacent to the Carquinez straights with a mile or two of marsh trails with good views of the straits, bridge, harbors as well as birds and flowers. Shorebirds are usually plentiful. Picnic tables, bathrooms and other amenities are also available. Note, as of this date, there are more trails than marked on the map, as well as a few other omissions.
