The name of the area comes from the "big break" which destroyed a levee protecting agricultural land in a 1928 storm. The walk (1.6 miles to the turn around by the Ironhorse Sanitary District ponds; a total of about 3.8 miles) was not as interesting as it might have been as the trail skirts the marsh and follows the edge of a residential development. However the Delta Discovery area was fascinating as well as informative.
