The former Wayne Golf Course in Bothell has now been converted into an urban green space, and provides an 89-acre open area for visitors to hike, picnic, play field games and enjoy nature right next to the Sammamish River. And don't worry about flying golf balls -- golf is no longer allowed in the area.
The area is adjacent to Blyth Park, if you wish to explore more of Bothell's urban parks on your trip.
