The Mustang Island State Park Paddling Trail consists of the North Trail (8.5 miles), the Shamrock Loop Trail (5.24 miles) and the Ashum Trail (6.8 miles). All of the trails follow the western shoreline of Mustang Island in Corpus Christi Bay, and pass through some of the best shallow-water fishing areas in Texas. The Ashum Trail follows the shoreline of Corpus Christi Bay over a firm sand bottom and allows for outstanding bird watching as well as sight casting opportunities. The Shamrock Loop Trail skirts the beautiful, protected waters of Shamrock Cove, where it connects with the North Trail, which follows the shoreline to East Flats and then meanders through marsh and spoil islands to the Island Moorings Marina in Port Aransas.
