Cascade Canyon is a stunning natural wonder located in Grand Teton National Park. Formed by glaciers that retreated around 15,000 years ago, the canyon boasts polished glacial rocks, hanging canyons, and impressive waterfalls like Hidden Falls. The Cascade Canyon Trail offers hikers a chance to explore the U-shaped canyon and enjoy breathtaking views of the surrounding peaks. With its rich geological history and scenic beauty, Cascade Canyon is a must-visit destination. This is an out and back hike so you can go as far as you want. There is a fork in the trail at 4 miles in, which is a good spot to turn around.
