Rocky Mountain National Park Report

5-5-2025

Expect flows to boost with the rain forecast this week. Tomorrow, you will likely encounter stained to muddy water, which may last into Wednesday. The higher flows will likely spread out fish from wintering holes into pocket water and smaller holes. Also of note re-paving is taking place before the Beaver Meadows entrance, so expect delays there. Hatches are Winter Stones, BWO's and Midges.

...

For dries, use a AR's BWO, High Viz Quill Midge, Griffith's gnat, Parachute Adams, Ms. Tickle Cripple BWO, Hippy Stomper and Chubby Chernobyl.

...

For nymphs, use a AR's Perdigon, BTS Mayfly, Two Bit Hooker, Juju Baetis, Zebra Midge, RS-2, Aero Baetis and a Blue Poison Tung.

Rocky Mountain National Park Fly Fishing

This may just be one of the best resources that the Front Range of Colorado has to offer. The “Park” as locals like to call it has too many lakes and streams to begin to speak about. The Park really has it all, from big browns in Moraine Park to beautiful native Greenback Cutthroats in high mountain streams and lakes. The Greenback is the Colorado state fish and was thought to be extinct around the turn of the century. Lucky for anglers a remnant population was found and RMNP has gone through lengthy efforts to return the Front Range’s native trout back to its home range. The park might be the best shot at finding what has been called the most beautiful cutthroat on a fly.

Rocky Mountain National Park has three entrances from the Front Range. From the east the main entrances are Beaver Meadows, which enters via highway 36, Fall River, which comes in from highway 34, and then there is the Wild basin entrance off the Peak to Peak Highway (Hwy 7). All three access great water. Highway 36 places you right near Moraine Park and the Bear Lake area. Moraine Park is best known for the meadow section where you can hunt nice brown trout in undercut banks while elk watch from a distance. The Bear Lake area has numerous high mountain lakes; Dream Lake is one of the highlights in this area.

The Fall River Road entrance via highway 34 has easy access to Fall River and the Roaring River. These rivers offer excellent dry fly fishing in breathtaking settings. Further up the trail there are some high mountain lakes that are well worth the 5+ mile hike in. This area offers one of the best shots at getting the Grand Slam; Browns, Brooks, Rainbows, and Greenbacks.

The Wild Basin area is just that, wild and fun. The head waters of the St. Vain run through here, while Longs Peak and Mt. Meeker set the backdrop for some of the more remote places in the park. This is another area where a Grand Slam is very obtainable.

Rocky Mountain National Park has some of the best fishing that the Boulder/Denver area has to offer. There really is something for everyone there, even beyond just fishing.
