The Ocala National Forest may not be a part of Orlando, it is not far from it. I have spent a great deal of time there just to get away from the hustle and bustle of the city. This is a great place to go if you want to go to springs, there you will find Salt Springs State Park and various other springs on the side of the roads down there. This place has such great bueaty that you can't help to feel the great peace it brings when you are there!
Pros: Inexpensive, Lots of space, Quiet tranquilty
