This is a great place to learn about water safety and operating small watercraft. The bike path goes right past the center, but the path is elevated and fenced off. The easiest way to get to the aquatic center is via the pedestrian tunnel on the other side of the highway. There are tables outside that make for a nice picnic spot.
