There are two miracle miles, one in Colorado and one in Wyoming.
Colorado is a fisherman’s dream. While it can be hard to single out the best fishing spot in the state, one thing most anglers agree upon is how spectacular the fishing is on a three-mile stretch river on the South Platte known as the Dream Stream and Miracle Mile.
The South Platte River is one of the most productive rivers to fish in the entire United States and the section between Spinney Reservoir and Elevenmile Canyon Reservoir is boasts a gold medal rating. This designation is given by the Colorado Wildlife Commission.
I have you do need to catch it at the right time of the year though. I fished it in the middle of the week and had the place to myself. I didnt see a lot of fish and didn't catch very many either. It was July when I was there though, March through April is the best time to fish that area. You wont be alone though.
There are some excellent places to fish in that state. I have a spot I hike into and fish, and I would rather fish it anytime then the miracle mile.
