Located right when Gomanche Creek flows into Silver River, Gomanche Falls is a quick plunge over layered slate rocks that splashes around on a hard creekbed. There are some upper drops too, located a short distance upstream along the pleasantly wooded creek.
Dynamite Hill Road heads east from US-41 a short distance south of L'Anse, along the long sloped decline near the famous Hilltop Restuarant. Turn down Dynamite Hill Road and follow it for 4.1 miles, bearing left at the final fork after it turns from pavement to dirt (and technically becomes Arvon Road). Park on the far side of Silver River, which passes under the road, near the unmarked gravel road that heads left through a sand pit. This gravel road (aka Dakota Farm Road) is usually gated.
Head through the gravel pit for a bit, parallel to the river. Stick to the left side when it opens up. A track will split off from the main road and head up the far left corner of the pit, try to stick to it when it turns back north and leaves the pit. Cut through the woods here, down the steep river bank on your left, making a beeline for Silver River. The falls will be across the river, upstream a short distance. Middle Silver Falls extends just past this waterfall and continues a long distance downstream.
