There is no parking specifically reserved for the Sumers Recreation Center, however there are several nearby parking options available to members.
Parking is enforced for all yellow spaces on campus weekdays from 7 a.m. to 5 p.m. while red spaces are enforced 24/7. Anyone can park in yellow spaces weekdays before 7 a.m. or after 5 p.m., or anytime on the weekends. During weekday enforcement hours, guests without permits can park in the visitor spaces in the Snow Way or Millbrook Garages for a fee of $2 for every two hours. 
Guests encouraged to carefully read posted signage before parking anywhere on campus in order to avoid being ticketed. The WashU Office of Recreation does not have the authority to forgive parking citations. 
There is plenty of bicycle parking next to the Sumers Rec Center and the U City-Big Bend Metrolink stop is only a five-minute walk from the front entrance.
