Fishing methods and approaches
Castle Mountain Lodge offers a prime fly fishing experience on the Fall River, with the season generally running from late spring through early fall. While the lodge itself provides access to its own stretch of the river, the true draw is the proximity to Rocky Mountain National Park and its abundant waterways. The fishing is best when the water conditions are optimal, typically from late May through early October, when the trout are actively feeding.\n\nThe lodge offers a free fly fishing class on Thursdays from mid-June through mid-August, signaling a peak period for those looking to learn or refine their skills. This period also aligns with the general summer season when the park is most accessible and the weather is most conducive to spending long days on the water. Anglers can expect to find Rainbow, Brook, and Brown trout, with catches ranging from small native fish to impressive 18-inch specimens.
