Do this park has grill or we have to take it

Park has many grills. No permits needed. Just keep clean.

Yes, it does. At least BBQ areas "Groove 1A" and "Groove 1B" have them, I saw. But I think you need to get a permit from park's administration to use them.

I haven't seen any, better to bring your own.

I would bring one. I don't remember seeing any here.

Groove 1 A, Groove 1B, Permit only

They have it
