For the past 20 years, the Humboldt Aquatic Centre has been a community staple for indoor activity.

On Wednesday, the city is celebrating the milestone anniversary during a three hour celebration.

Between 2:00 and 5:00pm, you can take a dip in the pool for free, as well as indulge in cupcakes and view some old photos.

The first 20 kids in attendance for the celebration will also receive a free single admission pass for the pool.
