Kids run wild, the lazy river is overrun with inappropriate kids being obnoxious, they discriminate against kids with disabilities quite frequently as well, there's no adult swim or consideration for the adults who are actually paying for memberships. It's kind of a zoo and it's a mess. We did one summer with them and will not be back. Just bad management across the board

It has a few slides to choose fromt and the lilly pad for the smaller ones. I didnt try any of the foods or treats that are offered by the facility.

Updating my review to four stars.

The pool needs to be skimmed more often and the lifeguards still do not keep people that are not swimming laps out of lap lanes like they should when they are being used. They let people just hang out and they are constantly getting in the way. The lifeguards I have met are very courteous though. Ryan and Caleb especially. They do a good job guarding and enforcing the diving board rules.

A very nice aquatic facility! I was invited by a friend who is a St. Charles resident. This pool is…read morefairly strict about non-resident passes, which I do understand and it is their right. It makes the pools less crowded, and I'm sure is easier on the lifeguards and maintenance staff. I have no complaints about my time actually poolside. However, I am knocking a star for their terrible online ticketing website. It appears they limit non-resident passes to twenty a day, which makes getting put into a que and then taken to another page, which was finicky, to pay with credit card quite annoying and also nervemaking, as I worried we had driven out for nothing as the number of tickets left went down... Anyway, I was impressed overall. Not sure I'll be back out before it closes for the season (mid-August, which seems early), but I was happy to invited once!

Blanchette Park was acquired by St. Charles in 1914, making it the oldest in the city's park…read moresystem. However, the updated park stands up well to newer parks. Its 44 acres include an outdoor aquatic center, baseball/softball diamonds, large playground (with rubberized surface), tennis/pickleball courts, horseshoe pits, football field, Ben Rau floral garden, picnic pavilions, and hiking trail. In winter, a park hill provides snow sledding. A serene spot in the park is set aside for the Angel of Hope statue, a memorial to all parents who have experienced the death of a child. Each December 6 an evening candlelight memorial service is held here.
