East Bank Campground

If you're looking for a convenient spot for a night or two and want to be right along the Big Hole River this would be a decent choice. There isn't much here - a few ancient tables and rock fire rings. Some are hard to get to due to the overgrown weeds blocking your path. The road is gravel as are the pads. All but two spots are in full sun due to there being very few trees. The lock on the bathroom doesn't work, didn't look like it had been cleaned recently either. No trash, no water. While all but one spot was occupied when I stopped in there wasn't anyone around - I think folks take advantage of it being free and use it as storage for their rigs through the week. The only site that had someone present looked a bit sketchy and I didn't feel comfortable staying there as a single female.
The boat ramp and day use parking area have plenty of room for several rigs. There are a couple of picnic tables along the river here too.
As mentioned in the other review, don't trust the name/location on google maps. The GPS coordinates here are correct. The camping marked east bank (on the west bank) on google is just a dispersed area accessed through the Bryant Creek turnoff just a bit east on the highway.

The first thing to note is the signage, it comes up quick and it’s easy to sail right by it. It’s a BLM recreation area with 9 camping spaces and a boat ramp at the other end. The camping is free and no water nor trash pickup, so pack it in pack it out. There are 2 pull thrus, one very large and another small one. The other (7) sites are backin. We camped here in a 37 foot fifth wheel, and would fit in most of the sites. Cell service is about two miles East at Dickey Bridge parking area. Also note if you check out this campground on Google Maps, it’s named incorrectly. Google maps calls this “Fish Creek Campground” and the area across the river they call “East Bank”. This (Google Maps) isn’t correct, we never found Fish Creek campground, and East Bank was the one between Mt43 and the Big Hole river. This campground roads and camping sites are gravel.
