Discover the biodiversity of a designated Provincially Significant Wetland and the incredible species situated in the understory of a mixed wood forest.

The Mills Block Conservation Area is located within the city limits of Thunder Bay and has become a popular site for recreation walkers, nature enthusiasts, wildlife photographers, naturalists’ clubs, and education groups.

The scenic wetlands at Mills Block have been designated as provincially significant for their dynamic biodiversity, rare species, and hydrology.

A looping hiking trail system (4 km) allows hikers to explore the wetlands and mixed-wood forest. Keep your eyes open for movement near the active beaver pond or amphibians sunbathing along the trail side.

The Mills Block Conservation Area is an extremely popular area for dog-walking. We urge all pet owners to keep your dogs on-leash at all-times while visiting the Cascades and that it is the pet-owner’s responsibility to clean up after their pet.

Look for hints of historical activities, as logging operations occurred in the late 1800’s into the 1900’s. A Forest Recovery Strategy was implemented in the 1960’s to replant over 200,000 seedlings to restore the old-growth forest.
