There are several parking options around Reliant Park, including over 15,000 spaces on the grounds. For location and pricing information, check out the link at the bottom of this post. A large private lot is located just south of Loop 610 at the former Astroworld site. This is not directly operated by the Houston Livestock Show and Rodeo, but helps ease parking congestion on-site at Reliant.
The Rodeo Express Committee manages a busing operation that maintains four private "satellite" lots around the area. This "park and ride" option is especially beneficial for folks making the drive from suburban communities. This busing service moves a quarter of a million people to and from the show each year. In addition to the Show's lots, METRO also provides bus service from the West Loop Park and Ride facility.
MetroRail is becoming an increasingly popular option. In 2009, nearly 125,000 patrons chose to ride the rail.
