Review for Rillito Park Race Track Review For Rillito Park Race Track Google User Sep 11 '16 at 5:03 Horse races are a blast at Rillito Park though races only run from February into March. There's no lower limit to betting so putting a small amount of money on races can be fun. Rillito Park offers stadium seating to watch races but you can also get up and close to the race. Visitors can also get up close to horses in staging areas as well. View full site to comment or like
