Camping and Kiting from ~ Miami Southwards

[fng]

In a couple of weeks, my daughter and I will spend a few days camping from somewhere just north of Miami down to the Keys.

What would be suggested sites that have good, clean, safe campgrounds close to reasonably good, moderately attended kite boarding areas?

Going to relax and work on basic skills with the daughter so a high traffic/skill area is not as important as a less than perfect area lightly attended.

Restaurants, nightlife, tourism and shopping are not the priority for this trip.

Appreciate any input on this one.
