September 8, 2021, update.
The Splash Pad at Willis Tucker Park will remain open through September 26th. Hours however, will be reduced to 11:30 am - 5:30 pm (with 1 hour closure from 2:00 pm - 3:00 pm).
This schedule is subject to change based upon weather conditions.
From a June 16, 2021, Snohomish County press release.
Throw on a pair of shorts or swimsuit and join the kids dodging the tricky soaker, silverflow cannon, aqua dome, water jelly, aqua jumper, power spinner, power volcano, water domes, and splash palace for a fun, family-friendly activity at the Willis Tucker Park Splash Pad!
Snohomish County Parks and Recreation adjusted to the new Phase 3 state guidelines and got everything up and running, so the splash pad is now open for the summer!
In a normal year without the COVID-19 pandemic, the splash pad normally opens the end of May (the Saturday of Memorial Day Weekend) and stays open until the warm weather ends in September.
There are three kite shelters next to the splash pad for reservation. These make a comfortable area for parents to lay out a picnic lunch or simply sit back and relax while keeping an eye on their youngsters playing in the water, on the playground equipment, or in the nearby sand box.
