Last summer I spent eight days fishing the Sun River (North, South and Middle Branch) in the Bob Marshall Wilderness. The ranch we stayed at was the only private property inside the one-million plus acres of the Bob Marshall that has no roads other than horse paths. It was a seven-mile horse ride into the ranch since there are no other ways in. My father had been out many times and fished many of the famous rivers in the west including the Boulder, Bitterroot and many others ones that get all the glory. We picked the Sun because of the lack of accessibility for most anglers. We only saw one other fisherman in the eight days fishing. On the other hand, all the famous rivers I saw such as the Missouri, Yellowstone, Madison, Gallatin and others were packed with waders and float boats. Looked like the opening day of Pennsylvania's trout season.
Each day we would jump on our horses and fish a different section of the river. We'd fish a few hours a day on the horse trip and then come back and fish near the ranch in the evening. They supplied a great breakfast, packed lunch and a dinner in the main lodge.
The fishing was unbelievable. Dad said it was without a doubt the best he has ever seen. It was easy to catch over 100 wild cuts, rainbows and cutbows each day. I also caught a handful of colorful brookies.
I won't say I caught any monsters, but an 18" wild cutthroat puts a big brownie on the Penns to shame when they run up waterfalls. Even the smaller fish put up a great fight in the freezing water.
Here are a few fishing photos:
