Agree with IC, Idlewild has to be prioritized over the others. And all of those courses are just as good in the winter (assuming they aren't covered in the occasional snow.)
Idlewild pairs with Lincoln Ridge. Keep in mind both are 24 hole courses but you really don't miss much imo if you just play the Idlewild Open layout (18 holes). That's what I choose to play. The other holes are decent, but just filler imo. You can also skip some poorly maintained and confusing holes at Lincoln Ridge (creek holes) to make an easier day.
Osage is an hour plus away from Idlewild. It pairs well with Stonelick (10 min), Johnson Hills (20 min) or even Echo Valley (probably 30-35 min). Echo Valley is in Idlewild's league, it's that good. Not saying it's better or even as good, but it really is that level of course. Kinda halfway between Cincy and Dayton.
Last thought, I think Hidden Ridge is better than Lincoln Ridge in NKY. Not a universally shared opinion, but I prefer the layout and feel. If you prefer Torma Town over Renny, you'd probably prefer Hidden Ridge over Lincoln Ridge. Also, assuming IC has it open I'll bet the maintenance is great in the winter, it's so much harder to keep up in spring and summer.
this is the money information for the area thank you so much
im from mn so i dont mind a little snow but i know others will not play once the flakes stick to the ground
