MISSOULA, Mont. — Splash Montana Water Park in Missoula is marking 20 years with a week full of activities, including scavenger hunts, lawn games and safety demonstrations. 

The celebration includes scavenger hunts, lawn games and safety demonstrations. 

Olivia Willoughby, an aquatics assistant with Missoula Parks and Recreation, helped plan many of the events.

Willoughby said the anniversary week also highlighted Splash Montana as a place where Montana families could spend time and swim with lifeguard supervision.

"I am really, really excited for our big Slam Friday evening. We are going to have super fun prizes, limited edition T-shirts and stickers as prizes. We're going to be giving out Dippin Dots as prizes. We're just super excited to give back to our community and celebrate these 20 years for a super fun time in the water," said Olivia Willoughby.

The schedule also includes adults-only events on Tuesday and Thursday from 7 to 9 p.m.
