Are we allowed to bring our charcoal and grill to the camping site also is it first come first serve on the campsites even if we have made a reservation?

It is first come, first pick of Campsites. If you have a reservation you are guaranteed your camp spot but get there early if you want to pick a good spot off the map. And yes bring your own Charcoal there are grills but you can bring your own too. The water at each campsite isn't drinking water it is brown so bring plenty to drink.

Star Galindo do u know of any good spot in the peacan grove area i think thats what is called

Yes and if you made a reservation they will give you a campsite when you get there its not first come first serve
