Kalamalka Lake Provincial Park and Protected Area is a provincial park in Coldstream, British Columbia, Canada. Located within the Okanagan region, the park encompasses a land area of about 978 hectares of pristine natural areas in the North Okanagan Regional District. Kalamalka Lake Provincial Park and Protected Area adopted its current name from Kalamalka Lake, for which it is located on its shore. During the process of entering summer, calcium carbonate forms crystals that reflect sunlight and create the vivid blue and green colours. Temperature changes in the fall and the spring sometimes create ribbons of deep blue colour in the lake, seen from the park.
