The Port Aransas route runs between two and six ferries a day and connects travelers on SH 361 a link across the Corpus Christi Channel between Aransas Pass, on the mainland, and Port Aransas, on Mustang Island. The two routes operate 24 hours a day, 365 days a year, weather permitting. More than 8 million passengers ride the Port Aransas and Galveston-Port Bolivar ferries annually.
