We have been going to Lake McConaughy for over 25 years. It has been a favorite camping destination for us as a couple and later as a family (kids range from 23-8). I have seen Lake Mac evolve over the years from a holiday retreat to the hot spot it is currently.
We have stayed in a variety of cabins as well and definitely some are better than others.
Whitetail property is every bit as picturesque as the photos display and can easily house 10, with room to move and enjoy a place to sit/lounge inside and out. The walk or drive to Ogallala Beach isn't far and the road is not busy if you want to ride your bike, take a jog, or enjoy some fresh air.
South Beach is not a high traffic spot which was great for my wide age range family. Locals asked if the bugs were bad, which, depending on the season, bring fly spray or bug spray, but nothing more then any other camp site we've stayed in.
Chose to stay at a VRBO due to a wedding and the drive across the dam was only 8-10 minutes. Not bad and again, not near the bulk of the campers, so made it nice to get away to our quiet space to rest and sleep soundly.
Would definitely stay again!
