The campground and marina services are fully staffed and the electric sites make extended stays comfortable; lake breezes often moderate heat on sunny days. Expect busy holiday weekends and higher occupancy, so reserve sites well in advance. Peak months: July, June, August Avoid: November, December, January, February
