The South Saskatchewan River valley, just north of Leader, is the largest tract of riparian woodlands between the Cypress Hills and the northern forests. The Leader Bird Watching Trail is suited for viewing many native bird species, including pileated woodpecker, golden eagle, lark sparrow, yellow-breasted chat, red-headed woodpecker, yellow-green swallow, great blue heron, prairie falcon, ferruginous hawk, long-billed curlew, short-eared owl, loggerhead shrike, and burrowing owl. It is also home to the prairie rattlesnake and one of few known localities of rattlesnakes in Saskatchewan. Checkboard Hill, 6.4 km west of Leader on Highway 741, has a wide view of the river and surrounding landscape.
