Bon Echo Provincial Park encompasses the central section of the lake, including the narrows between North and South Mazinaw and the Bon Echo Rock formation attracts rock climbers from all over the world.

Bon Echo rock, located on the eastern side of North Mazinaw, features over 260 native pictographs- often confused with petroglyphs – the largest visible collection in Canada - including the Ojibwa trickster figure and culture hero, Nanabush.

The rock also contains a tribute to Walt Whitman, inscribed by Horace Traubel And Flora MacDonald Denison, who ran the Bon Echo Inn on the site of the provincial park during the 1910s.

The inscription reads “my foothold is tenon’d and mortised in granite, I laugh at what you call dissolution and I know the amplitude of time.” A dam is located at the outflow of the lake to maintain the level of the lake and to control water flow into the Mississippi River during the spring runoff time.

Peregrine Falcons have been reintroduced to the area- nesting on top of Bon Echo Rock.
