I camped for one night on Hontoon Island. There is a small parking lot off the beaten path. My GPS was able to direct me to it. We were picked up on the dock by the ferry and brought to the island free of charge. The staff member was very friendly and helpful, bringing the firewood and tarp we purchased right to our campsite.
We heard and saw many little critters, like armadillos and raccoons. We had quite an audience of shiny eyes in the bushes while we roasted marshmallows.
The entire campsite is small, so you can see and hear the cabins and other campers near you. But there aren't a lot of sites, so it still has a secluded feel. It's definitely less crowded then the more popular Blue Springs State park nearby. There are plenty of trees, and every site is well shaded.
One downside, like a lot of FL, it is very damp. Some sites have raised sand beds to put your tent on to keep you out of the mud. We used one of these and it really helped keep our tent dry and clean. It was essentially raining or misting for our entire visit. A word of advice: be prepared with tarps, rain gear, and lots of bug spray.
On the positive side, there are a lot of outdoor activities to do nearby. You can canoe down the river, go bike riding, hike, and fish. Blue Springs State Park is only a short drive or canoe ride away, where you can swim and inner tube down the fresh, clear springs.
