Parking costs $1 at Willowmoor Weir.
Boats can access Lake Washington from the weir.
The park is a good size with many areas for play.
A few nearby places worth checking next.
I have been using it now for 3 months and it saves me so much research. Reduces the need to call and double check every time.
How did I not know these places existed?! Atly's scoring is a lifesaver, now I can finally find THE spot without wasting time Googling my life away.
