Penguin park is so much fun. I remember going there when I was little, and now when we visit back home, I love to take my kids there. The big animals are always exciting for the kids to see, and now they have lots of fun areas to climb, swing, and run around. There is also a nice covered picnic area where we hosted a birthday party one year. My only complaint is that the nice soft stuff they have on the ground to keep the kids from getting hurt if they fall also seems to absorb the heat, so this park seems especially HOT on really sunny days. Your kids will love this place!
My family and I were tickled pink to find a nice park close to our house. Penguin park is an old park, but has recently been refurbished with new soft ground cover (like on a track and field track) and has three areas of playground equipment for various ages. There is also a nice covered picnic area and restrooms right in the middle of the park. Compact, but very family friendly!
Penguin Park is a Kansas City favorite. It is north of the river, so we don't get there often (maybe once a year or so), but we love it every time.
Penguin Park has lots of play places for both the toddler/preschool group and the older grade school kids (and everything in-between). Our favorite is the elephant and the giant penguin of course (how could it not be). There are giant slides, plenty of things to climb, these giant animals to explore, and plenty of other play equipment.
There is a restroom on site, which is fantastic. There is also a shelter and picnic area. When we go to Penguin Park we like to shoot up I-29 and grab lunch at Zona Rosa (there are tons of choices, though our family favorite is O'Dowd's, the Irish Pub).
In December the park puts on Santa's Workshop. We have only been once due to scheduling conflicts, but it was tons of fun.
We've been taking our son for five years now to the park and he loves it everytime.
