Shell key is a favorite local spot for my boyfriend and I. The greatest thing about camping here is that it's super cheap, secluded, and so beautiful. Sunsets are to die for. Tons of edible flora, and fishing of course. Plus, shell key is one of the very few places you are allowed to have a fire on the beach in FL. If you're up for hot, unpredictable weather and sand everywhere, I would recommend trying out this spot.
