The state's signature
Crane staging at Jasper-Pulaski
Tens of thousands of sandhill cranes stage at Jasper-Pulaski Fish & Wildlife Area each late fall — and the DNR publishes an official count every Tuesday, so you can watch the number build toward the late-November peak.
Seasonal RV-timing verdict
When Indiana is at its best
Indiana's prime RV window is April to June and September to October. Comfortable temperatures and lower humidity; summers are warm and humid while winters bring snow and ice. Shoulder-season play: March and November offer good rates but prepare for cold nights and possible early or late snow.
Know before you go
Tornadoes and severe storms peak in spring. Summer humidity can be oppressive in the south.
