This is new since I've moved to AL and I am so glad to have seen it while visiting Columbus last week. My son had a blast playing in the water features and jets while the adults of our group were able to see (and talk to) him from the outside seating at the bar/restaurant adjacent to it.
Although there is no pool of water, there were lifeguards on a Thursday afternoon. Luckily nothing occasioned the saving of any lives while were there, but an inconsiderate dog walker strolled through and let their dog pee on the edge of the play area. The lifeguard workers turned off the water and cleaned up the spot, no doubt a valuable service appreciated by all.
There is also a 3-D mural on the sidewalk that we enjoyed "playing with." The ladies room was spacious, clean.
What a great free attraction! Most of the parking meters nearby are in the shade, bonus!
