Mustang Island State Park is a practical public RV base for a Gulf Coast trip because its reservable campground is close to the beach without putting the electric sites directly on the sand. TPWD lists 48 campsites with electricity, water hookups and 50-amp service. The sites sit behind the dunes roughly 400 yards from the water and have restrooms with showers nearby, giving travelers a more conventional campground setup than the park's primitive beach option.
TPWD also lists 50 primitive drive-up beach campsites along a 1.5-mile stretch of beach. Those sites are non-reservable, lack the electric-site amenities and may close because of weather conditions, so they should not be treated as interchangeable with the 48 electric campsites. Travelers with larger rigs or specific power requirements should reserve the electric campground and confirm any vehicle or site limitations before arrival.
The park often reaches capacity, and TPWD highly recommends reservations for both camping and day use. Spring and summer are the busiest seasons, while Gulf weather can affect beach conditions at any time of year. Before towing onto the island, confirm current park alerts, the electric-site reservation and road conditions. Texas Defined uses licensed Mustang Island imagery and relies on TPWD for current rules rather than assuming that older beach-camping information remains valid.
