Do they offer full R.V. hook ups? If so what are the rates? TIA

They have electricity and water at most of their camp sites. Please see the full list at https://www.floridastateparks.org/parks-and-trails/mike-roess-gold-head-branch-state-park/experiences-amenities

Yes

They also have a dump station.

We have been here all week. Water. Electric and extra clean bath house, but no heat. Been pretty cold this week. Campound almost empty. Nice big campsites.

Thanks For the info 👍
