With over 350 miles of trails to roam and covering over 265,000 acres, Rocky Mountain National Park offers boundless fishing opportunities for the casual angler to the most seasoned. Several rivers, numerous small streams and over one hundred high mountain lakes abound with healthy, hungry trout. The Park's waters contain all wild trout, with a great chance of catching the prized Colorado Grand Slam: Brook, Rainbow, Brown, and Cutthroat Trout, including the native Greenback Cutthroat, once thought to be extinct but now thriving in its natural habitat.

The Big Thompson River below Lake Estes is a closer option, and contains some of the best fly fishing in the area, with its first 8 miles all catch and release. Moraine Park in Rocky Mountain National Park is a favorite among anglers, with easy accessibility, plentiful hungry trout and a beautiful setting. The Roaring River and the Upper Big Thompson above Fern Lake trailhead are also very popular destinations. Although they do require a hike, they award the angler with a less populated setting and excellent fishing.

High mountain lakes are also a rewarding spot for anglers and can either be fished by spotting cruisers along the banks or by wading or belly boating out into the deeper waters. Lily Lake, a beautiful, drive-to lake, contains all Greenback Cutthroat Trout and has great dry fly action in the summer's early evenings. Lake Estes and Mary's Lake are also popular, drive to lakes and are good for not only fly fishing, but spin fishing as well. Rocky Mountain National Park is home to many high mountain lakes thriving with fish and within a day's hike. Your best bet is to contact a local fly shop for lake locations, fishing conditions and seasonal weather hazards.

A guided trip is the best way to ensure an optimal fly fishing experience in the area, whether you are a novice fly fisherman or woman or a seasoned angler. Learning local waters, fishing conditions and the best fly patterns will provide you with the best places to fish and how to fish them most effectively.
