  • We were here late November and there was no snow on the ground this year. We had the place pretty much to ourselves. The sites were level and there were pines and cedars, picnic tables and electrical ...  more »
  • Keyhole is the jewel of NE Wyoming. The fishing is great and camping is right down the middle of wild but not. Some areas are quiet and others are filled with people. The weather and time of year dict...  more »
  • This was a nice stop. We had lunch at the beach area. It was pretty windy today, so wasn't really excited about the area, but if we were camping or had a boat, this would be great. Maybe next time.  more »
  • Great area and well kept campground. Facilities are good enough considering they are vault toilets. There are no showers but there is a facility in Pine Haven that has incredibly beautiful shower rooms - only about a 5 minute drive from the main entrance of the park. Staff very friendly and the regular boaters in the area were very courteous on the water. Saw lots of fish although I am not a fishing gal, but the reservoir seems well stocked. The store at the marina is also pretty well stocked and decent prices on items. Young staff but they were responsive if a little less than courteous.
  • Great campsite. Family enjoyed the bike ride from our campsite to the beach and skipping rocks.
  • I Love going to Keyhole, I went camping and swimming there when I was young with my parents and sister. Now I take my kids there every year camping with my husband. It's so Beautiful and peaceful!
  • My family and I went to the beach near the Marina. It was a nice time. A little crowded, but nice for a lake beach in Wyoming. The area was clean and there were buoys to keep boats away.
  • Very friendly staff at the entrance. Park is a bit tame for the area, though. More of a campsite than a sight seeing place. The picture on Google maps is misleading you cannot view devil's tower as part of keyhole. You can get to it through there but you have to pay a separate fee. All in all it wasn't what I was looking for but it definitely looks like a cool place to chill and camp.
