Another guest review, thanks to Big H & Little H!
Johnson Road Park in Keller (640 Johnson Rd) is Big H & Little H's favorite park! They love all the "towers" to climb up & the slides. It can be difficult to keep up with more than 1 kid (or I'm guessing even just 1 sometimes) because there is so much equipment. There is a toddler play area also [not pictured] with a smaller playscape, swings, & a digging area with a "digger". There is a huge field, basketball courts, 2 covered pavilions, & a nice clean restroom right next to the play area. The park is well maintained & always clean. It's one of the most popular parks though, so it can get quite crowded. The park shares a parking lot with the Keller library (which has a great storytime) & the Keller Senior Activity Center.
