The French River flows through typical Canadian Shield country, in many places exposing rugged glaciated rock but also through heavily forested areas on the upper portion.

The mouth of the river contains countless islands and numerous channels which vary from narrow, enclosed steep-walled gorges, falls and rapids, to broad expanses of open water.

This led to increased exploration and interest for fishing and logging during the era of the Industrial Revolution.

The French River was "ripe for the picking with its seemingly inexhaustible supply of timber and proximity to the American markets".

French River continues to attract vacationers and cottage owners who enjoy the clear water, superb fishing, rocky shores and pine growth forests.
