Till dark unless you are staying over
This state park does not have a telephone in its headquarters at the gate, from what I remember. You will have to go on the internet and look up the park to find an answer to your question. You can also post a question on their website that they will answer as soon as they can. Lastly, you can contact the Texas Parks and Wildlife they have all information for all Texas State Parks.
Park closes at 8 or so unless you are camping. I would call and ask.
