This was a cool little random find for my brother and I to visit while in the Tampa area. Not a whole lot to the park (regretfully we didn't go over to the river), but it features a nice sized parking lot, natural beauty covered in Spanish moss, and, of course, the old standpipe tower!
I was hoping to access the top, but they have it pretty well sealed...but the gothic carvings were neat, and the tower quite photogenic. Apparently they light the top up at night, too.
