The dump is located in the back of the state-run RV park. It is easily accessed from the parking lot of the first beach parking area as you exit. There is an RV dump fee that must be paid at the entrance. The fee is $4.00 for park entry, which is good for all day at the beach. Potable water and rinse water (non-potable) are available at the dump station. To get to the dump station, after arriving on South Padre Island, take the first right and follow Texas 100 to the park entrance gate. The staff at the gate can direct you to the dump station from there.
