I would like to go scuba diving on Catalina island for my birthday next month. I don’t have any experience and I am staying there for four days. I would like to just learn how to scuba dive and go on a diving trip that lasts just for a few hours or so. Is there a place that teaches you, gives you a scuba diving trip, provides you equipment, and is affordable in one place? Or should I just forget it?

You can take a "resort course". This course will expose you safely to one dive.

In California, PADI (www.padi.org) gives a list of SCUBA certification places. PADI is located in So Cal.
