The Split Rock River waterfalls feels like you’re really out in the woods, but you can be there and back in a half hour. The hike starts on the west side of the river climbing a half-mile through birch forests to the falls tumbling 20 feet over grey rock into a rock-edged pool. You can turn around here [1+ mile total] or hike another three-quarter mile to an impressive red rock [rhyolite] gorge with 50-foot cliffs and twin red pillars. This is another point where you can turn around [2.6 mile total]. If you choose to continue you will see a few more waterfalls over the next 3/4 of a mile. At that point you have to cross the river [in the water] and pick up the high east trail which showcases wide open Lake Superior views.
