We stayed here over Labor Day weekend. It is located in a remote area outside of Uvalde. There is not a lot to do. They have a trail down to a quiet part of the Nueces river, which at the time was very low. There pool was nice and was not crowded at all. It had just re-opened from maintenance. A really nice splash area for kids. And some nice shade areas.
The park was less than a 1/3 full. The ants (including fire ants) were very bad at our campsite. I bought some ant hill killer and that helped. But still got bit up by those pesky brats. Not sure this is the parks fault but perhaps they could fertilize with insect killer.
Wifi is free with a hitch. If you want to use more than 1-2 devices on lower speed, you will need to pay a small fee for up to 4 devices at streaming speed.
Final negative was that they ask you to wear wristbands during your visit. We did not wear them and didn’t get into any trouble. But we only visited the pool once and never went to office/store.
