Watching Grand Prix at the desert horse park

I’m going to be down in Palm Springs for work in a few weeks and want to go watch the Grand Prix on Saturday while I’m down there. Does anyone know if you have to buy tickets or can you just go watch? I’ve never been to that horse park and not sure the system. Thanks!

You only need a credential to enter the park. It is free though. Here is the show premium that will answer your questions including schedules.

Used to be a parking fee only, but not maybe now under new ownership.
