Actually, last summer wifey and I visited some fam up in Deltona, and my cuz took us to Blue Springs. Effin' gorgeous, man. I wish I'd taken a camera.
It is this beautiful natural spring that stays at about 72 degrees F all year long, and you can wade/swim along most of it pulling an inner tube until you reach the bubbler, which is a big sinkhole in a grotto surrounded by lush foliage. We tied the tubes and swam across the bubbler, and there were people diving down into it. The water was crystalline, and incrediblt fresh.
Then after swimming across and down into the sinkhole, we got on our inner tubes and rode the mellow current all the way back downstream to the little dock.
Amazing place...and I've been told there are tons of them. Too bad they're not anywhere near me.
We're supposed to go jetskiing next weekend near where the tennis tournament that used to be Lipton is held. Miami has its plusses, but the natural beauty (besides the human female kind) tends to be further up north.
