Wisconsin's most challenging whitewater river — the Roaring Rapids section delivers continuous Class IV–V through a remote granite gorge in the Marinette County forest. Five-Foot Falls, Horserace Rapids, and the infamous Terminal Surfer have tested expert paddlers for decades. The Peshtigo is also remembered for the 1871 Peshtigo Fire — the deadliest wildfire in American history, which killed over 1,500 people along the river valley.
