Re: Montana Trip Advice
I would definitely consider the Bighorn River on your trip. You could camp out at Cottonwood Camp which is about a 1/2 mile from the 3 mile access. The fishing should be unbelievable in July. You can walk the river all the way up to the Dam. You can also rent boats there go site seeing up into the Canyon up top at the Dam. There is also a campground on the Afterbay Dam right on the little Lake before it dumps into the Bighorn. You can also hire guides up there, I would recommend David Palmer through the Bighorn Trout Shop.
If you have anymore questions about it just let me know.
