About this course
Ralph Williamson Memorial is the disc golf course at Dick Thurnau Memorial Park in the White Center neighborhood of Seattle — rolling hills, views of the Olympics and Cascades, and one hole that plays across the water. Keith Lionetti's 1989 design plays 5,065 feet at par 55.
Free to play with concrete tees and Mach 7 baskets, it's pet friendly, cart friendly, and has restrooms on site. The multi-use park setting means you'll share the space with other visitors, and the water comes into play more than the modest length suggests.
One of Seattle's hidden gems — scenic, friendly, and tougher than the scorecard looks.
Hole 18 is the longest at Ralph Williamson at 607 feet — a par 4 that plays across the water and gives the course its most memorable moment. With the Cascades or Olympics on the horizon and the hazard in play, it's the hole that makes this neighborhood park feel like a destination.
