Invite your friends and neighbors for a free evening of family fun at the Snoqualmie Valley YMCA. Jump in our castle bounce house, race down the giant blow-up slide, start a pick-up game of basketball, soccer or dodgeball or practice your jump roping skills. Parents are encouraged to participate in all of the activities with their children. Play as a family, have fun, laugh and get moving together! Free for Facility and Community Members! Community Members, please bring your photo ID.
