Its trailhead located across Zimovia Highway from the Shoemaker Bay campground, this 4-5 mile hike is steep, but spectacular. Beautiful Rainbow Falls comes into view after the first mile. Climbing past the falls, hikers are rewarded with views of Chichagof Pass and narrow Zimovia Strait. Past here, follow the Institute Creek Trail 1,500 feet up to Shoemaker Bay Overlook.
