Rocky Mountain National Park

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.

A great Front Range brown

RMNP is fishing well all over.  Keep a good eye out for weather as we do see thunderstorms roll in many afternoons this time of year. Here a few good places to try.

Moraine Park: Mornings and evening are best here.  Bright, sunny days make the mid day fishing here hard with spooky fish.  If you get an overcast day, Moraine can fish great with dries.  Try caddis and BWO imitations and also start working with your favorite ant and terrestrial patterns.  Upper Moraine and Fern Lake Trailhead have been fishing very well.

Glacier Creek: Glacier is low but productive for the stealthy angler.  Dry dropper with your favorite atttractor (mine’s a Hippy Stomper) and beadhead (jigged pheasant tail) should do the trick.  The fish are spread out and be careful on approach, but you should have a great day on Glacier if you decide to fish here.

Fall River: Also fishing well, although now lower and very, very clear.  Light tippet, delicate approaches, and smaller dries have been the answer here.  Try small caddis, small BWO’s, and small Ants or Beetles here.

Lakes: Reports of good dry fly action for good sized cutts have been flowing in.  If you feel like a hike, Hiyaha, The Loch, Lawn, Fern or+

Ouzel lake should be on your radar.  Well worth the extra work to get here.
