Save this map and reel so you can find Hidden Falls in St. Paul, Minnesota! Hidden Falls is so well hidden, most people never find it. It took me a few tries and asking several people before I finally found it. This waterfall is tucked into the back of Hidden Falls Trail in St. Paul, Minnesota. The full loop is 1.3 miles and has beautiful views of the Mississippi River. There are no signs so save this reel and follow the trail to the red X in this video.
