Pole Bridge campground is an undeveloped campground with scattered tables and fire rings. There is a vault toilet and is situated in a lightly wooded area. Warm River goes through the campground but is a small creek at this site.
From Ashton, ID, head east on ID-47 for 15.8 miles (approximately 1 miles past the Upper Mesa Falls turn). Turn right onto the Warm River Rd (Forest Road 150). The road comes to a junction in about 3 miles and you will want to continue left for another 5 miles. Turn right into the campground. If you come to Forest Road 153 you went too far.
Beautiful scenery with enough dispersed campsites that you aren't right on top of each other. A bit of a bumpy dirt road for the last stretch. The mosquitos ruined the experience. They were there in droves and I wish I was exaggerating.
Grew up going to this campground. It's a great reminder of childhood every time we go back. The campground itself it well maintained. Couple things to be aware of, it is high mountain dessert, so while there are trees there is also a lot of grass and open area. Second thing is as always a reminder to those that come out here, clean up after yourself! So much toilet paper all over, we cleaned it up at our spot and burned it, but how gross to be camping in other peoples toilet paper. Burn it or Bury it. Leave no trace!
Contrary to some forest service sites, there is no bathroom at this campground. No garbage bins either. The area is pretty, but doesn't have any views of surrounding mountains/topography. There is great access to the river, which is more of a creek at this point (about 15 ft across and no more than 3 ft deep). There are fish in the river, but the fishing isn't very good compared to other places I've been. You're surrounded by lodgepole pine forest. The campsites themselves are too close together for an area with this much room. Campsites have fire pits, picnic tables, and bear boxes to keep your food. Mosquitoes are horrendous early in the year because the surrounding area is quite marshy, but once it dries up the bugs are only bad at dawn and dusk.
