I have a few things that I would put over a lot of things on this list
I would add visiting Lincoln State Park. ( Abraham Lincoln's boyhood home) There's an Old village, a lake with a beach camping, & hiking. If you're going to visit Holiday world. It's right down the road. It's worth it.
And with the turkey run trip I would add tubing/ kayaking down the sugarcreek.
As well as -
- thunder over Louisville ( you watch from the banks of Indiana ) huge air and fireworks show every April.
- Newport Hill climb Old fashioned cars/ motorcycles drive up a hill and are timed. Along with vendors and shopping.
- Indiana Beach theme park.
Monticello, Indiana. Cool! Laid-back old school boardwalk theme park. Lots of roller coasters the most picturesque Park I've been to. Very unique. Must see.
- exotic feline rescue center point, Indiana get up close two Lions tigers, cougar other small cats and fox. ( All rescues)
- there are other show caves in Indiana Wyandotte cave, square boon caverns, Indiana caverns, And Blue spring caverns.
- spring Mill State Park.
- French lick/westbaden. Lots to do in the area. The old hotel , casino, indoor go-karting indoor water park and there's an animal Safari close by as well.
- for women covered bridge festival. ( Shopping & food )
I was born, grew up in and live in Indiana. Believe me there are not 25 things worth doing in this state!!! The only areas that are of possible interest are cities & towns. Bordering other states.
