Knapweed Rodeo

Knapweed Rodeo

First Saturday after August long weekend - Saturday, August 6 from 9 am to 4 pm

Wrangle up your posse to help us control spotted knapweed in Waterton Lakes National Park. Volunteer for a half or full day. Try your hand at winning one of the many prizes at this fun-filled day for the whole family. Spotted knapweed is an invasive plant species that impacts native ecosystems. A single plant can produce up to 140,00 seeds, every year!

Help us corral knapweed before it goes to seed at the Prince of Wales Hotel National Historic Site hill. We’re working to remove all the knapweed from this area in time for the hotel’s centennial in 2027. Don’t forget your cowboy hat!
