Hi Catherine. There is no fee to enter Potomac Overlook Regional Park. We do not allow grilling at Potomac Overlook Regional Park.
Yes, it is free to get in the park and to visit the nature center.
No fee. If there are grills (never looked for them) they would be free too
There are picnic areas, I do not recall if there are grills. And like Mr. Hunter mentioned, free of charge.
There is no fee.
