Apparently Hot Springs has some strong mobster ties. Al Capone used to come to this "Ohio Bar" in town's center.
We came to Hot Springs for the Arkansas Derby at the Oaklawn race track. (Word to the wise: reserve your spot and uber/taxi's are almost non-existent after the last race.)
We did not have an interest in trying the bath houses/hot springs lining the main street, I've heard it's a good experience though.
Good clean air, nice people, easy pace.
I'd go back.
