Lady Evelyn-Smoothwater Provincial Park is a remote wilderness park in northeastern Ontario, Canada, near Lake Temagami. It is one of five provincial parks located in the Temagami area.
This park encompasses Smoothwater Lake, Makobe Lake, the Ishpatina Ridge (highest point in Ontario), Maple Mountain (highest vertical rise in Ontario), and most of the Lady Evelyn River. The park also includes many waterfalls, such as Helen Falls, the highest waterfall on the Lady Evelyn River.
Lady Evelyn-Smoothwater lies within the Eastern forest-boreal transition ecoregion. It offers protection to some of the last remaining stands of old growth forest in Ontario, and is home to the endangered Aurora trout.
As a wilderness park, few services are offered to visitors but it is ideal for backcountry canoeing, nature exploration, and wildlife viewing. The park hosts fire towers on top of Ishpatina Ridge and Maple Mountain, accessible by foot trails.
Lady Evelyn River was established as a park in 1973. In 1983, the park was expanded to its present area of 72,000 hectares.
The region has been home to the Teme-Augama Anishnabai for thousands of years; within the park, Maple Mountain (Chee-bay-jing) is traditional sacred site.
Throughout the park are remnants of logging activities from the early and mid-1900s.
