Peter Kirk Park is a very large park in the heart of downtown Kirkland, right next to the library, pool, teen center, senior center, theatre, and bus station, but unfortunately it is not designed for young children.
The equipment is really big and dangerous for little ones. It offers many wonderful, appropriate risks and challenges for older kids, and there is an attached skateboard park, so I highly recommend this one to anyone with elementary-aged children. There are also tennis courts, a basketball court, drinking fountain, picnic benches, and baseball fields. If you go during library hours, you can use the library restrooms, or you can walk next door to the QFC or Starbucks, buy a little snack (so you’re a customer), and use their restrooms. (Warning: the QFC restrooms are up a flight of difficult stairs, and they won’t let you use the first floor restroom unless you are in a wheelchair. This is one of several reasons it is NOT, and never has been, a stroller friendly store!) Parking is on the street, or in the parking garage under the library. Do not park at the QFC or senior center.
