Cascade River Professional Review and Guide
"If it’s a good workout you’re looking for along with picturesque views of a tumbling whitewater river, climb the trail that follows the Cascade River inland from the North Shore. For spectacular views of Lake Superior, side hikes extend outside the park to Moose and Lookout Mountains, both of which rise 600 feet above the lake. Along the hike, the trail ventures close to the riverbank for views of waterfalls and then away from the river where the Cascade’s rushing water can be heard far below.
The hiking trail climbs more than 600 feet upstream along the west side, crosses over on a county road, and then journeys back down the east side. Portions of the trail are steep, and other portions cross wet areas on log bridges or boardwalks, so protective footwear is a must. This is a strenuous hike along a narrow, volcanic canyon that carries a rapidly moving river to Lake Superior, but it’s well worth the effort."
