Russell and Miriam Grinnell Memorial Nature Sanctuary at Bare Bluff

Copper Harbor,  Keweenaw County

Hiking Trails | Snowshoeing Trails

The sanctuary contains most of the top of a 588 ft. high monolith known as Bare Bluff which rises from the shore of Lake Superior on the south shore of the Keweenaw Peninsula. From the clearings on the top of the bluff, a popular 180 degree spectacular view opens from Manitou Island to Point Isabelle to Bete Grise. This bluff is the most prominent feature on the south shore of the Keweenaw Peninsula. The sanctuary contains stunning geological features including exposed cliffs, bluffs, and rocks as well as a substantial amount of intact forest among a much larger forested landscape for wildlife. The bluffs provide warm air drafts for raptors to catch during migration.

Access is difficult and dangerous. Reaching the lookout requires a 300 foot climb, but both the lower and upper level are accessible with proper preparation and caution.
