Seasonal RV-timing verdict
When Kentucky is at its best
Kentucky's prime RV window is April to June and September to October. Mild spring and fall are perfect for horse country and bourbon trail RVing; summers are humid and winters damp. Shoulder-season play: Late March and early November are quiet but can have frost or heavy rain that affects gravel roads in state parks.
Know before you go
Spring flooding along rivers is common. Summer brings high humidity and occasional severe storms.
