South Joe River Chickee is probably the easiest chickee to reach from Flamingo. The Joe River goes around the Southwest end of Whitewater Bay.
The chickee itself is a little off the channel of the Joe River, but if you watch carefully it's easy enough to find.

It's an older chickee, so it's smaller and actually feels a little rickety (but it has ridden out several hurricanes recently). As the pictures show, it's a double chickee, so you might have to share it with another party.
Being as close as it is to Flamingo, it probably gets used a lot but I have never met other parties there in Summer (though I did in April).
