Cardinal Creek Valley is a new park and splash pad out in Spring Ridge. (It’s not on the city of Ottawa 2011 PDF map, but it is listed on their site and their open data.)
Wow, is it ever cool.
They have a giant yellow flower that sprinkles water from the top onto the petals. (If you stay close to the green pole, you can stay relatively dry!)
They have another giant metal structure that pours water onto a plate that sprays the people below.
I like the two water guns that spray water into the center of the splash pad (but the water turns off so you can’t spray people behind you.)
There’s a giant blue circle that sprays water that you can run through.
Finally, there’s an assortment of water fountains that spray up from different parts of the floor. (My favorite is the little one on the side that playfully spits up a little stream every now and then.
