Spray Valley Provincial Park, Provincial park in Kananaskis Improvement District, Canada

Spray Valley Provincial Park is a mountain protected area along the Spray River in western Alberta with lakes, hiking trails, and camping grounds. The terrain spans diverse landscapes that support wildlife and offers visitors access to natural features throughout the seasons.

The area was explored in 1801 by David Thompson and Duncan McGillivray, who traveled along established routes through the valley. Spray Lake reservoir was created in 1950 by dam construction, substantially altering the landscape.

The park lies in Kananaskis Country, a system of provincial parks and wildland areas managed together, and borders Banff National Park on the west. A management plan approved in April 2006 restricts off-road vehicles, snowmobiles, horseback riding and biking to protect ecological integrity, while leaving room for a possible small lodge site in the valley.

The park is reached by road via the Bighorn Highway. Summer camping runs from the Victoria Day weekend in May to Thanksgiving weekend in October at Lillian Lake, Ribbon Falls, Ribbon Lake, Eau Claire and Spray Lakes West; in winter only Buller Mountain and Eau Claire stay open. The Sparrowhawk and Mount Shark day-use areas are open year-round.

Spray Lake reservoir now offers opportunities for water activities and shows how human development has shaped the mountain landscape. Visitors can observe the contrast between the original river system and the modern reservoir while exploring the park.
