Summit Lake is a very nice place to get away for a weekend from Indy but not so much a destination spot. Friendly staff and well maintained. Wooded spots that are water adjacent are beautiful. Since it’s a no wake lake, the noisiest thing is usually the geese
You can rent a small boat by the day and keep it at your camp site.
It’s a great place to watch the water or take walks. Not a lot to do otherwise. The beach is not worth the trouble.
