If you don't mind a bunch of fish swimming around you while you say your vows, an underwater can be one unique wedding venue.
This wedding took place on San Andres Island, Colombia, but there are many other places around the world you can have a scuba-diving wedding, such as Cancun, Mexico or many spots in Hawaii.

A little closer to home for you in the western U.S. is San Diego, where one wedding officiant will arrange a wedding for you most anywhere in San Diego, including while scuba diving. You can call Ricki Douglas at 760-734-6532 to request information.
