South Fork of the Flathead River

Flowing from deep within the Bob Marshall Wilderness, the South Fork of the Flathead has been called Montana’s most inaccessible river.

It is beautiful and striking in a hundred different ways. This river hosts an unbelievable number of ravenous, native Westslope cutthroat trout that flip over dry flies and huge bull trout that will give you the fight of a lifetime. You will flip too, over the remarkable fly fishing here in Montana and the restful solitude found at this Orvis endorsed fly fishing lodge. You’ll never release the memories you catch here.

The South Fork of the Flathead River is pristine and virtually untouched, just the way it was 100 years ago. Our cutthroat trout are genetically pure and they love dry flies! Your guide will provide the perfect selection, from big foam stoneflies to ants and hoppers! They also love grabbing streamers, eating nymphs and occasionally smashing a hopper!

Spotted Bear Ranch is proud to offer Montana’s only legally guided bull trout fishing. Bull trout are a threatened species and our river is their last stronghold. The season runs from the 3rd Saturday in May through July 31st. These fish start their move in high water and will be in the river system all year long. Bull trout love chasing cutthroat on the end of your line!
