Rainbow Trout

Chasing rainbows near Louisville, Colorado, offers a unique angling experience defined by the small, accessible waters of the Boulder Creek watershed. While not known for trophy trout, these streams, particularly those closer to the foothills, hold wild and stocked rainbows that provide a fun challenge for fly anglers and light tackle enthusiasts. Spring and fall are prime times, as the water temperatures are moderate and the trout are actively feeding. Avoid the high flows of spring runoff and the heat of mid-summer. A great access point is along the Coal Creek Trail, offering easy access to the creek. Remember that these are sensitive ecosystems, so practice catch and release and use barbless hooks to ensure the health of the fishery. Local tip: Smaller nymphs and dry flies tend to outperform larger patterns in these clear, shallow waters. Be stealthy and watch for rising fish!
