The Aqua Splash Park features more than 80 inflatable obstacles that float on a sandpit lake just south of I-235 and Seneca.  For an hourly fee, people of all ages can try to maneuver through the course without falling in the lake – though that is half the fun of it. Sprinklers will help ensure that the inflatable slides, swings, ramps, wiggle bridges, ladders and trampolines are slippery.
