T&C Sports campus is closed by order of the City of Austin — the park is not open for customers or the public; municipal orders do not permit people gathering on the fields or in parking lots. For more info, visit the T&C website.
The one avenue that is still available as long as the City of Austin permits it is the Lake Creek Trail that runs through the T&C campus. Walkers, runners and bicyclists are allowed on that sidewalk and T&C wholeheartedly supports those activities. However — It is essential that they stay on the sidewalk and not venture on to the T&C grounds.
