Sites are nice and private, and the campground was quiet the whole time. The firewood available ($6) was dry and burned well, although you do have to cut it yourself. There are saws provided at the pile near the water spigot. The ranger was very friendly too. No doubt about it, it's not the easiest hike in but wasn't too bad. I don't suggest doing it on a 90 degree day like we did, but jumped in the river (1/2 mile or so from campground) right after which felt great! One of the bathrooms (the one near the water and woodpile) smelled SO STRONGLY of ammonia from the vault toilet that you could taste it and feel it when you took a breath inside of the bathroom! I have a very strong stomach and it was tough for me to be in the bathroom long enough to use it. Park was notified. I would stay here again, although I personally think that $27(20/night + 7/reservation fee) for one night of backpack camping is pretty steep. Pics are of the woodpile and site 22. Sites were clean and maintained.

We had a hard time finding this place via Google maps and had to switch it into topographic view to find our way there, as Google maps did not take us the correct way. Nice sites but it was very windy when we arrived and had to use the car to block the wind to even get the tent set up, which took 2 of us. Having good and long stakes was helpful for this. $12/night if you have a MT fishing license and $18 if you don't. Great big sky MT sunset here. Would stay here again if passing through. Clean campground. Lots of spots available on a Sunday evening when we stayed there.

We really enjoyed the 3 nights we stayed at Atherton creek! The campground was full when we arrived on a Friday so the host put us up near the boat launch and we were able to snag a spot in the actual campground the following morning. Site #19 is probably the best tent spot in the house with a beautiful lake view and some good trees for shade. Clean restrooms and drinking water available. FYI the road to the campground has some sizeable pot holes so use caution on your way in! Made it just fine in our Prius but it required some swerving to avoid bottoming out. Firewood available from the host. Would definitely stay here again.

Nice, clean campground in the national park. The campground itself is free but you need to purchase a pass for the park. No host or registration required. There are some marked sites in the center of the loop but you can camp pretty much wherever you can find a spot, as long as you're within the campground area. While we were cooking dinner a buffalo walked right through! Clean restrooms, but no water so remember to bring some. There were hiking trails around the campground and the sunrise was beautiful from the top of the hill.

This place was great! Only stayed here one night passing through on our way back to MN. Very well maintained and clean, huge campsites that are well spaced from others. There are campsites all around the lake/park, some in their own little private nook. Great sunset and the bugs were minimal too. Very surprised that a place as nice as this one is free. The freeway is somewhat close just across the lake and can be heard, but it didn't bother us at all. Campsites have a picnic table and fire ring. Vault toilets are scattered around the lake, and there are water spigots too. Happy we found this place!
