About Sleeping Giant Provincial Park

Sleeping Giant Provincial Park is a provincial park on the Sibley Peninsula in northwestern Ontario, protecting the prominent rock formation known locally as the Sleeping Giant and surrounding wilderness.

The park is visited for its extensive trail network, cliffs and panoramic viewpoints. Notable opportunities include the summit routes that look out over Lake Superior, day hikes along rugged shoreline, and backcountry camping in designated areas.

The area has been used for recreation and conservation since it was set aside as a provincial park; management focuses on hiking access, camping infrastructure and protecting shoreline and forest habitats.

The park sits on the Sibley Peninsula on the north shore of Lake Superior, adjacent to the city of Thunder Bay on the western end of Lake Superior; the park occupies a large portion of the peninsula and fronts the lake.

  • Outdoors: The park contains rugged cliffs and headlands along Lake Superior and a number of maintained trails suitable for day hikes and multi-day backcountry routes.
  • Key viewpoints: The best viewpoints for the silhouette known as the Sleeping Giant are reached via the Top of the Giant trail and other summit routes; these offer broad views over Lake Superior and the Sibley Peninsula.

  • Hike the trail up to the Sleeping Giant's summit (the Giant's Nose) early in the morning for clearer views and cooler air.
  • Bring a warm layer even in summer-the exposed top of the formation can be windy and cold.
  • The park's coastal cliffs can be slippery-stay on marked trails and keep dogs leashed near edges.
