Hey Karli. Welcome to Florida and welcome to the forums. I live about 20 minutes away from Altamonte, and there are a few places to take your Jeep, but they're not exactly just down the road.
Like Rebel said, check out florida jeepers, there's a lot of nice folks over there that will help you out with anything.
As for public off-roading spots, you can go out 46 to Scottsmoor, or up to the forest in Ocala. Other than that, there's been quite a few spots shut down in the past few months, so its best to just get to know some people who have property.

There are a couple of Jeep clubs around. I live in Lake Mary and belong to the Mid Florida Jeep Club. On May 17, 18, 19 we are having Jeep Beach in Daytona. I would love to see you come out for it. On Saturday we are having trail rides and a show and shine. Im forgoing the trail ride to enter my Jeep in the show. We are giving away huge prizes, raffles, ect. On Sunday we are having a parade on the beach at 9am and then parking on the beach for an all day event. If you want more info just PM me back. Jeff
