Pennask Lake Provincial Park is a provincial park in British Columbia, Canada, located on the easternmost heights of the Thompson Plateau, to the northwest of the Okanagan town of Peachland.
Pennask Lake is a high elevation lake that has multiple spring creeks flowing into it. The park takes in two bays at the southeast corner of Pennask Lake. Peterson Bay is a long, narrow bay which provides entry into the main portion of the lake from the park. Chapman Bay is a shallow, confined bay at the north end of the park. The park fronts one kilometre of the lake's south shore.[1]
