Is there fire grill to have a picnic? Or is there on close to innbrook?

Yes

Grills in playground area only

They don't have a fire pit or anything like that, but they do have one of those pedestal type charcoal grills at the picnic shelter near the playground.

There are grills at the playground area near the entrance.

Echo lake park is closer to innsbrook and has a grill area. I don't believe crump has anything like that.

I don't think they have grills. There are sheltered area though by the ball field.
