Set in natural woodlands this park is home to more than 30 native animals and birds, as well as a few exotics. Static and interactive displays are housed in an interpretive centre. On the same site is the Greenwing Legacy Interpretation Centre which features displays on waterfowl and wetlands developed in cooperation with Ducks Unlimited Canada.
Abundant gypsum deposits have influenced the landscape and vegetation in and around the park. Home to rare plants and fossils, Smileys also protects stands of yellow birch and hemlock. Bordered by the Meander River where you can fish or pan for gold.
