Since time immemorial the Blackfoot People occupied what is now Southern Alberta and Northern Montana. Part of this vast territory includes Waterton Lakes National Park. Waterton is home to numerous sacred sites that contain the history and knowledge of the Blackfoot People.

The Park is significant as it was used for ceremonial, hunting, camping, trading and healing purposes. In the Blackfoot Language, Waterton is called "Paah-tó-mah-ksi-ki-mi" meaning Inner Sacred Lake.

Paahtomahksikimi Cultural Centre's mission is to help visitors connect with the spirit of Waterton while educating about the history of Paahtomahksikimi.
