In 2012 Coronado Beach was selected as the Best Beach in the U.S. by "Dr. Beach".
San Diego Beaches
What IS different is San Diego's attempt to provide swim-able, fit-for-humans water to serve the state's warmest beach destination, often plagued by water quality issues that this border region faces. Outdated infrastructure or lack of adequate treatment facilities for years have made the southernmost beaches less fit for people. San Diego's Port Authority had injected millions of dollars into sewage treatment facilities to help make San Diego beaches better, and the results have been noticeable.
