Baja Cali Vacation ideas ?

We are thinking about going to Baja for 5 days but dont really want to stay in a trendy/expensive Cabo San Lucas type of location . If I wanted to be around a bunch of fat drunken Americans Iwould stay home..lol . We prefer a quieter more local type of environment . We dont require fancy lodging .
Close to water .. maybe some fishing ... local restaraunts .. scenic.
Any hidden gems you know of ?

We would be flying into the Cabo airport so it needs to be reasonably close ( 100 miles ) or we could fly into southern California and drive south .
