Rainbow Trout
Rainbow trout fishing near Milliken requires a bit of a drive west towards the foothills, but the reward is worth it. The Cache La Poudre River is a popular and productive destination. This freestone river offers a variety of water types, from fast-moving riffles to deep pools, providing habitat for trout of all sizes. Spring and fall are ideal times to fish the Poudre, as the water temperatures are more moderate. Fly fishing is very popular, but spin fishing with small spinners and spoons can also be effective. A local tip: check the Colorado Parks and Wildlife fishing regulations before you go, as there are specific rules and restrictions on certain sections of the river. Also, be aware of changing weather conditions, as storms can roll in quickly in the mountains. The rainbow trout in the Poudre are known for being selective, so experiment with different fly patterns and presentations. Nymphs, dry flies, and streamers can all be effective, depending on the time of year and water conditions.
