Getting a campsite at Mustang Island State Park

How do I get a campsite at Mustang Island State Park when it's sold out?

Cancellations happen constantly — the trick is being first to know. Set an alert for your dates and we'll watch Mustang Island State Park on Texas State Parks around the clock, then notify you the moment a site opens. Alerts run on a Pro subscription ($9.99/mo, cancel anytime).

When do campsites usually open up at Mustang Island State Park?

Whenever someone cancels. Most reservation systems refund less the closer you get to arrival, so cancellations cluster in the days before a stay — but the openings themselves are unpredictable, which is exactly why watching for them beats refreshing the page.

At high-demand Texas parks a cancelled summer-weekend site is often rebooked within minutes — sometimes under a minute. Being notified the instant it opens, with your Texas State Parks login and payment already saved, is the difference between getting in and missing it.
