  • 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...  read 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. 
  • Perfect place for everybody. Small children, teenagers, adults, seniors... good for celebrations and any event. It has a nice beach and cliffs to jump from. It has several campgrounds, some with full ...  read more »
  • 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!
  • 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.
  • Quite with plenty of wind to go around. Very fun place to spend a week. Awesome rock formations and cliff faces... must boat to to see.
  • 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.
  • Great place for camping. I strolled in there on a whim. Just looking for a place to get off the road for the night. Plenty of different camping position options. Designated fire rings in each lot. Also cabin options if you choose to reserve ahead of time. A couple of bodies of water for fishing. Variety of wildlife in the area as well.
