The upper part of Otter Creek provides natural spawning beds for speckled trout, with the falls itself fed by small beaver ponds above the canyon.

Species flowering later in the season include viper's bugloss, bladder campion, yarrow, evening primrose and a variety of asters.

The Algoma Central Railway began development of the Agawa Canyon Wilderness Park in 1952 with the clearing of a picnic area.

With increased service from Algoma Central's Agawa Canyon Tour Train, the area's natural environment makes it a tourist stop.

Between 1918 and 1923, several members of the Group of Seven painted in the Algoma region including Lawren Harris, A. Y. Jackson, Frank Johnston, J. E. H. MacDonald, and Arthur Lismer.

To access this area they rented a boxcar from The Algoma Central Railway, which had been outfitted like a cabin and was shunted to sidings near choice painting locations.
