We stopped here for one night on the way to Yellowstone. It is a county park. There are 6 or 8 back in sites that are not on the water. We just parked on a spot that was pretty level about 20 ft from the water. Beautiful view and nice and peaceful. Dry camping only. Located about 5 miles north of Buffalo and easy to get too. We parked here with a 35ft FW and did not even unhook. Loved it and highly recommend it for a one night stop over. Would stop here again. Not sure how many sites, just guessed. We camped here in a Fifth Wheel.
True Wyoming experience, the lake is the 'swimming pool'. Fish, boat, dive or just watch from your site. Established sites have fire pits and tables, or you may park anywhere for $6 a night, including the South end of lake. Pit toilets, no showers but very rarely crowded. We camped here in a Motorhome.
