You should look up the old town trolley. It's a trolley that takes you all over st. Augustine and it takes about an hour to get around. One of the stops is the Castillo de San Marco. Its hop on and off and you can ride it all day. It's probably the best way to see as much of st. Augustine as you can in a day. Then you wont have to pay for parking at Castillo de san Marco.
There is also a parking garage nearby that is $15 for the day
10.00 parking, But if you are disabled, with handicap parking its FREE!
There is a parking just in front of cementary. $10 all day.
