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.

Fishing Report Date: 05-21-2015

For a month or so we have been experiencing a very wet Spring and there seems like there is no end in sight.  But there is great news, the fishing is still amazing!

With the rising water levels and the snow falling in the high country it seems almost silly to venture outside and fish, but for the past few weeks fishing has been nothing but amazing.  Yesterday we went into Rocky Mountain National Park and fished Moraine Park.  We were hit with every type of weather; rain, snow, sleet, wind, hail and to my great amazement blue skies.  But that did not deter us from getting out and enjoying ourselves.

When we reached the Moraine and looked into the stream I was amazed to see that the water levels were at a normal height and the stream was like looking through glass.  We started off with a dry dropper and a straight line rig with no luck.  We had a few lookers and a handful of strikes that we missed but fishing was starting off slow.

After two hours or so I decided that we needed to go back to the basics of fly fishing and fish with a single dry fly, a Parachute Adams.  And when we made that decision it turned out to be worth it. Within seconds we were getting strikes in the slow pools as well as the faster water.

We hooked into a couple of fish before they started hunkering down for the night, but using a single dry fly seemed to be ideal.  Most of the fish tended to be either out in the open in slow moving water or they were hiding under the bank.  They were podded up in each hole we found them in and were very skittish.

The fly selection I would recommend using would be a single Parachute Adams, size 18-20.  But I would still try and use a dry dropper with nymphs such as rainbow warriors, Juju Beatis, copper ribbed RS2s, and psycho princes.  Use sizes 18-20, maybe smaller if the weather gets colder.

And lastly make sure if you are fishing with nymphs that you get them to the bottom with weight and put them as close to the bank as possible.  And I would strongly recommend fishing on your knees with longer cast to avoid detection.

Be sure to get out this weekend even with the weather staying with us and enjoy the beautiful landscapes of Colorado.
