Wet'n'Wild Water Park, the biggest waterpark in Toronto, is opening up for its 2025 season in just a couple of weeks, kicking summer off with a major splash. Things are already heating up as Toronto gets closer and closer to summer 2025, and one of the best ways to cool off on steamy, sunny days is about to make a comeback. The 30-year-old waterpark boasts 45 acres of unique attractions that run the gamut from utterly exhilarating to pleasant and peaceful, so that no matter what you're into, you can have the day of your dreams. This summer, the waterpark is also introducing a brand-new events calendar teeming with extra special activities, like bubble parties, poolside DJ parties every Thursday and Sunday afternoon, Dive-In movie nights and Shockwave, an after-hours 21+ event series with DJs, drink specials and glow foam. It all kicks off on June 7, when the water park officially opens for the season, but advance tickets and passes are already available through Wet'n'Wild's website.
