We stayed at The Trout Hunter in September, and had a great stay. The lodge is two-story, so every room either have a patio or a balcony. The rooms were utilitarian, clean and comfortable and all have a view of the river from a balcony or patio.
The lodge is both a gathering spot for fisherman about to leave and returning from their trips, and there is a fly-shop in the hotel. I am sure they would prefer if all of their guests were fisherman, but seemed to tolerate our group regardless. The staff was friendly.
The chef took pride in his presentation and food quality. Great breakfasts.
The internet connection was not that great, but we found that to be the case in other places we stayed in the Idaho/Wyoming/Montana area. At night people gather outside the restaurant and bar, or are on their balcony or patio talking, so one who is sensitive to noise should ask for a room at the far end of the hotel.
We used it as a gateway to Yellowstone and found it convenient to both Yellowstone and the nearby state parks.
The sunsets were fabulous over the river, which is 50 yards from the hotel.
