Our guide mostly features activities that are in Lewisville, Flower Mound, Highland Village and the surrounding areas, so the link below will only include aquatic centers from the Colony east, but there are pictures, rates, and amenities listed, so you can get a good idea of they may be worth the drive for a change of pace.

Personally, my kids (8 & 10) love Sun Valley Pool in Lewisville. Old Town Lewisville is for younger kids. Flower Mound CAC has added some new shade structures and water features this season.
Good luck! Sounds like a fun summer!
