Here are some nice swings tucked away next to I-5 on Beacon Hill, pretty near to Georgetown.
Location: Corson Ave S & S Snoqualmie St. on the southwestern side of Beacon Hill.
Number of swings: 4 regular, 1 baby seat, 1 baby bucket
Ground material: Wood chips
Chain length: Medium-long.
I had an enjoyable time here. There are lots of trees surrounding and a huge grassy hill behind. It's a mostly residential area, but that means you're more likely to swing in peace.
How to get there: Bus route #60 stops along 15th Ave in both directions.
