4. Flaming Geyser State Park
Flaming Geyser State Park is in a scenic spot along the Green River and a not-too-distant destination for some Eastside and South King County-area families. The meadows at this park are popular with people flying radio-controlled aircraft and drones; kids will find this fun to watch if flyers are out. There's the river to inspect (though do not swim in spring even when the weather is hot; the water is way too cold) and kids can try to figure out why this park is called Flaming Geyser. Four miles of hiking trails take families into the woods.
