Black River Harbor is one of the most scenic and popular locations on the Ottawa National Forest. Walk along the docks and have lunch in the picnic area. Go across the Black River on the 60 meter suspension bridge, built by the Civilian Conservation Corp in 1939. Enjoy old growth hemlock-hardwood forest along the river. Hike to five scenic nearby waterfalls: Rainbow, Sandstone, Gorge, Potawatomi, and Great Conglomerate. Camp at Black River Harbor Campground. Swim in Lake Superior at the beach during the summer.
This Geocache will take you to a less-visited corner, with a nice view of Lake Superior. After crossing the suspension bridge, take the trail to Rainbow Falls. The trail will include a bit of a climb and many steps. After you get to the top turn left and follow the path north to Lake Superior. Admire the view and then go off trail a short distance to the cache. Please stay off the steep slopes.
When you're done I recommend the 3/4 mile hike to Rainbow Falls (part of the North Country National Scenic Trail). The view is better on this side of the river.
As of 2019, there is now a $5 day use fee at Black River Harbor, from May 15 through September 30. Thursdays are free. The Ottawa National Forest sells $30 annual passes. The $80 interagency federal passes also work.
