The Dream of a Lifetime. Five Rivers Lodge, open for Montana fly fishing year round, offers comfortable elegance in a place considered to have the last un-crowded blue ribbon fisheries in the U.S. Fly fishers, beginners and experienced alike, find challenges while fly fishing Montana’s Beaverhead river, Big Hole river, Ruby river, Jefferson river and Madison river plus private spring creeks and ponds that receive little fishing pressure. Birds, waterfowl, wildlife and wildflowers are abundant in this mountainous section of the Lewis and Clark Trail.
