We travel a few thousand miles a year with our RV. Keyhole is a must for our spring/fall itinerary (We haven't been there in the summer). Beautiful, good-sized lake. Quiet. RV sites are in the trees, very near the lake, and not right on top of each other. Great showers ($$). Rangers are plentiful and friendly. We do a lot of kayaking without any problems with motorboats--there's room for everyone in the spring and fall. Pit toilets are well-placed and about as unpleasant as you would expect. Nearest grocery store/gas is about 4 miles away.

Quiet, But Needs Attention

We stayed here for 4 days in the tatanka campground. Sites are fairly spaced out, and of decent size. Fairly close to level. Area was quiet, but there is a ton of boat traffic, and people tend to drive laps near the boat launch, and will park their trailer and vehicle literally anywhere-including the space in front of your campsite. Bathrooms were kind of gross, and in desperate need of attention. Trash receptacles were overflowing, and smelled so bad it wafted across the whole campground. Finally, the workers here were not helpful. The main gate has a sign saying parks pass enter left, pay a fee enter right. We had already paid our reservation, and had parks passes, so went to check in on the left. Attendant said she couldn’t check us in on that size, because it’s the “fast lane”. I literally backed up my trailer, and pulled to the other size of the 6x6 hut to check in. A bit ridiculous. Ok place to stay, but don’t expect much. Wyoming State parks seem to be ok at best.
