I'd like to recommend, for getting out into the real areas of Florida, you can't beat leaving the Miami metro area and going up US27 out toward the glades and up to Lake Okeechobee.The are also many, many great state parks in the area, way too many to list. I'd recommend going to the myflorida.com website and go to the floridastateparks site . Choose an area and read further. There are also many great places east of Okeechobee in the Fort Pierce and Vero Beach area, not a far drive from the Miami/Dade metro area.If you had time, I'd recommend also the drive south to the keys, even if you didn't go all the way to Key West.Also, next trip, visit many neat not so touristy areas in the Tampa bay area and end with a day trip up to the Homosassa/Crystal River areas, known for manatees and crystal clear rivers, such as the Rainbow, and many springs all the way past Gainesville.
