Medicman,
From Panama City you can do 4 lighthouses in a day trip (St.Joseph Point, Cape San Blas, Crooked River and St. Marks). I would like to tell you that you can also do Cape St. George on that day trip but unless you have a boat I'm afraid that one is out of the question. I have tryed to get out to Cape St. George on several trips but the best that I could find was a charter boat that would cost $75.per person.
I do want to see it, but not that much! The other 4 you can drive right up to. Good luck to you on your trip, I hope you have a great time! Panama City is a nice place to visit and they have the best beachs.
What dates will you be there? I'm heading that way myself Oct. 10th.
