The Mustang Island shoreline follows along the Gulf of Mexico from the Port Aransas Jetty all the way to the Packery Channel which divides Mustang Island and North Padre Island. Entering on to the Nueces County Beaches of Mustang Island can be accomplished several ways. From the Port Aransas Jetty or Horace Caldwell Pier just continuing to follow the beach road keeps you on the Mustang Island Shoreline. Avenue G will also bring you to the beach, turn right or south and continue along the beach. Sand conditions can be soft at times. Beach Access Roads 1 and 1A also provide beach access further south of Avenue G. Beach Access Roads are paved and connect to State Hwy 361.

The Mustang Island shoreline will provide an opportunity to see many coastal bird species. Plovers, sandpipers, terns, herons, gulls along with other species can be seen along the shoreline.
