NOTE: Hollys dump station is still closed. There is a "mini dump" station for portable tanks behind the bathouse. You can dump at KOA for 35$ or at other state parks for free.
This was our second time at Holly. We stayed with 2 other groups sites 65-68. The sites are huge. Some have more shade than others. Power is set up very close to the asphalt pad. Water spigot was 3 sites away. Outhouse was about 5 sites away. Kids enjoyed the playground & dogs enjoyed the trails. Fire pit was huge & clean. Will definitely come again.
