  • 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 »
  • Don't let the size of this lake fool you, it's a ton of fun. Fishing, boating, swimming, kayaking, etc. Will fill your day with a ton of fun. The lake is really clean and has natural coal so it may be good for your skin. This lake is cheap and very worth a visit.
  • Grew up on these waters. I love it here. Anytime of year.
  • 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.
  • Close to Devils Tower. Lots of privacy and the swimming is good. No lifeguards.
  • We stayed here the late part of Decwmber. This year there was not snow. The campground was quiet and there were still ducks, seagulls and bald eagles to be seen in the morning. We had electrical hookups and water was available. The sites were pretty level with some pines and cedars. We enjoyed our stay.
