I have camped Caprock in July and done the drive inn theatre, which is a really neat deal, very family, extremely polite rural kids from the area gather there. Its a great park. The dirt is very red. A fishing lake but no real swimming water.
Heading south Abilene is also a nice old park with a pool. Town of Buffalo Gap nearby is a nice place to spend a day knocking around, fun shops.
Heading south from there and worth seeing are South Llano at Junction and then a drive through of Lost Maples on the way to Garner. At Garner living in holes beneath the concrete on the bank of the frio just down from the screen shelters is a species of O. palmeri different from any other, possibly a yet to be described subspecies.
Balmorhea is simply a place everyone need to go swimming. Be sure to take mask/snorkel for everyone.
Ft Davis I have only been to for Thanksgivings. I prefer the scenic drive to town. The fort is not a state park so your park pass won't get you in there.
I don't think I have ever been to Ft Davis when there was not a burn ban and I like a camp fire as part of my camping, even in summer.
With the central and western parts of the state in severe drought, it may be that the streams and scenery will not be at their best this summer if we don't get rain.
Make sure you take your dipnets and send me the crawdad photos here
