Marymoor Playground

If you live anywhere near Redmond, this place basically becomes your second backyard. The playground itself covers all the bases — slides, swings, a solid climbing structure, and a seesaw that the kids will fight over — but honestly the surrounding park is what makes it worth the trip. You’ve got a bike track, soccer field, and walking paths that connect to trails along the forest edge, so there’s something to do even after the little ones are done playing. Restrooms are genuinely clean (a bigger deal than people admit), and there’s plenty of parking plus picnic tables when you’re ready to eat. It works for all ages, which means you’re not stuck splitting up the family.
