Review for Arapahoe Park Review For Arapahoe Park Google User Nov 3 '18 at 15:29 Only open in the summer for 12-13 weeks....a wonderful little fair style racetrack, easy to park ( no charge ) and $ 3 admission ( over 55 $ 1 and under a certain age is $ 1 or free ) besides live racing they offer tv viewing and wagering on horse racing from around the country....wish they were open year round.....
