Fourmile creek looks fishable, but in my experience holds little to no fish and with the loads of better fisheries nearby, I wouldn’t worry much about this one. We added unfishable rivers that sometimes we get questions about to help anglers not waste their time like we did on the creek 🙂 Go check out North Thompson Creek nearby for small stream experience or any of the great fishing on the Roaring Fork, Frying Pan or Colorado Rivers

Fourmile Creek of Roaring Fork River (Not Fishable) Access Map
View our access map for the Fourmile Creek of Roaring Fork River (Not Fishable) and learn public and private access points as well as other notable features around fly fishing this river. We include headwater and confluence data and in an effort to not "hotspot" river access points that are better than others, we list every access point available. This serves two purposes. First, it keeps us from hotspotting, which is just showing the best spots and bringing unwanted and harmful attention to the specific access point. The second reason is while we want to help you catch fish and find great places to explore, we don't want to spell it all out for you. If you get it all spelled out, we're doing the exploring, not you. Missing out on the journey of exploring places to fly fish is one of the more enjoyable aspects of fly fishing. While not everyone has time to go explore everything in person, we provide some of the top level data to help you know if something is worth your time, then pass it off to you to explore and find your own adventure.
