Wildcat Canyon is a steep little rugged gorge on the far west end of the Silver Lake Basin, a very remote area of Marquette County. A tiny creek drains a series of swamps down the canyon and over a wide variety of waterfalls. Some of the drops are tall split cascades over hard rock, some are sideways slides along slabs, while others are direct plunges that foam up as the crest. Huge mossy rocks and tall trees surround the creek and create a wonderfully scenic hike.
Head north on County Road FX (or Wolf Lake Road) from US-41 for 8.7 miles until the road starts to curve west up past Brocky Lake. Turn right on Grapevine Road, following it's loop for 1 mile before turning left at the fork. Take a right at the fork at .3 miles. Keep on this 'main' dirt road for 5.3 miles before turning right down a small track that leads over to the Dead River's inlet to Silver Lake Basin. Park at the camping spot.
Follow the track across the river on foot, walking along the western end of the basin. The track gives out after less than a half mile, continue on the shoreline until you bump into Wildcat Canyon Creek. Follow this creek up the hill, crossing the North Country Trail on the way to view the uppermost falls.
