Transit card

St Louis has the MetroLink light rail and MetroBus network, both usable with a reloadable Gateway Card or contactless bank card tap-to-pay. Cliff Cave Park in south St Louis County is not directly served by a MetroLink station or clear bus route, so this is effectively a car-access venue for race day.

Single rides run about $2.50 if transit is used to reach the general area.
