Rocky Mountain National Park offers a truly unique fishing experience. The park’s high-altitude lakes and streams are surrounded by towering peaks, lush forests, and open meadows, creating an awe-inspiring backdrop for anglers. RMNP fishing is as much about the experience of being in unspoiled wilderness as it is about the fishing itself. The park is a sanctuary for several native fish species, including the greenback cutthroat trout, which is Colorado’s state fish and one of the most sought-after catches in the park.

Alpine Lakes

RMNP is home to several alpine lakes, many of which are teeming with fish. These lakes are often located at elevations above 10,000 feet, offering not just great fishing opportunities but also stunning panoramic views. Popular alpine lakes for fishing include Dream Lake, Sky Pond, and Mills Lake. Each lake has its own unique charm and fish population, making it worth exploring multiple spots during your trip.

The Big Thompson River and the Fall River are two of the most popular streams, known for their healthy populations of rainbow and brown trout.
