From what I have heard the best place for whale watching would be Cabo. You can also see them in Mazatlan and Puerto Vallarta but Cabo probably has more to see. I am not sure about which companies, but I am sure if you do a search, you will find several good choices. Maybe someone has had an experience and would like to share.
If there is anything I can help you with about Mazatlan or PV, let me know please.

Take care
