Big Hole River Dispersed Camping

If you prefer boondocking this is a decent option with easy access to the river....as long as you don't mind a stray fisherman or two wandering by your camp.
There are about 11 sites scattered along the two track dirt road. Two entrance points about 2.5 miles and 3.25 miles SW of the Fishtrap Campground along Highway 43. The NE entrance is fairly level and open, the SW entrance has a bit of a hill down from the highway and then a very narrow gate to cross through - I had maybe 6" clearance either side of my jacks. If you have a larger rig you may want to stick with the NE entrance. Locals have no problem getting their 25-30' rigs in here. The road is dirt and can be muddy in the spring and fall. Some of the middle sites may be inaccessible in the shoulder season and all off limits once the snow starts falling.
Sites are in a sage brush prairie, no trees or shade. The area can be windy and expect swarms of mosquitoes most of the summer. Rock fire rings are established in each site. The Big Hole River is just steps away from each site and most of the folks camping here are here to fish. There was a lot of road noise from the traffic passing on the highway but thankfully "heavy traffic" here is no more than 5 cars an hour. There's also some road construction going on this summer so expect more noise/traffic during the work week. Other campers and fishermen were the only traffic who ventured off the highway and the fishermen mainly stuck to parking near the entrances.
I stayed at the most SW site and it was probably the smallest site back here. Plenty of room for my rig and the views of the river are amazing. My usual evening camp routine is to sit by the fire and read but I was more than content to just sit and watch the river.
