Does anyone know if its possible to rent a panga in Punta Mita for a few (2-3) hours, and the approximate cost? We would like to go out to the Marietas for seabird photography--but the organized trips, as far as I can find, are full day trips with snorkling, lunch, etc...we don't want all that.

Alternatively does anyone know of a trip that is half-day and leaves from Punta Mita?

yes anythig is possible.Just go and talk to fisherman...
