Montana Trout Tours
Want the best of Montana in one week? We’ve teamed up with Montana Fishing Outfitters to offer the 406OnTheFly Trout Tour. It’s two or three days of float fishing the fantastic Missouri River. Then it’s a quick trip down to Bozeman/Livingston and a float on the Yellowstone or Madison Rivers plus a day or two in Yellowstone Park or on the spring creeks. Or you can do it in reverse order, whatever is more convenient, the fish certainly won’t care. Contact us for more info.
