About Rocky Forty Falls

Rocky Forty Falls is a quiet, lesser-known cascade tucked into Michigan’s Upper Peninsula and favored for its peaceful, forested setting. The falls are modest in size but photogenic, with a series of small drops that create a soothing soundtrack amid the trees. Because it doesn't attract the crowds of some larger UP waterfalls, Rocky Forty is a great choice for hikers seeking a more contemplative outing in nature. The approach is an out-and-back trail of about 2.4 miles (3.9 km) round trip with roughly 350 feet (107 m) of elevation gain, rated moderate—so expect a few short climbs and uneven footing in places. The nearest developed camping is the Black River Harbor Pavilion, roughly 18.9 km (about 11.8 miles) away, making day trips common for visitors; bring sturdy shoes, water, and a camera for the best experience.

The Setting

Rocky Forty Falls sits at 1,253 feet along the Black River, in the foothills of Michigan.
