Mustang Island is a barrier island on the Gulf Coast of Texas in the United States. The island is 18 miles (29 km) long, stretching from Corpus Christi to Port Aransas. The island is oriented generally northeast-southwest, with the Gulf of Mexico on the east and south, and Corpus Christi Bay on the north and west. The island's southern end connects by roadway to Padre Island. At the northern end of the island is Port Aransas, beyond which is San José Island (also known as Saint Joseph Island). The Aransas Channel (also known as the "Aransas Pass"—for which the nearby town on the mainland is named), formed by the separation of Mustang and San José islands, is protected by jetties extending into the gulf from each island. - Source: Wikipedia
